Migrating Customer data along with relationships (CRM) using LSMW

1 Introduction This document provides a simple and user-friendly step-by-step approach for working with LSMW. The document mostly covers the practical usage of LSMW with respect to Batch input Recording Method.

This document may be used to gain an insight of LSMW process in SAP CRM environment and may be used as a guide to help the consultants during the initial loading of master data into SAP database tables.

2 LSMW The Legacy System Migration Workbench (LSMW) is a tool that supports data migration from legacy systems (non-SAP systems) to SAP systems. It is a cross-platform component of the SAP system. The tool has interfaces with the Data Transfer Center and with batch input and direct input processing as well as standard interfaces BAPI and IDoc.

The tool migrates user-defined datasets (known as objects), which are combined according to business criteria instead of individual tables or field contents. In addition to using standard import techniques, the user-specific objects can be generated.

The LSMW supports a one-time transfer of data (initial data load) and also offers a restricted support of permanent interfaces. Thus, a periodic transfer of data is possible. The LSMW, however, does not include any functions for monitoring of permanent interfaces. The tool does not support any data export interfaces (outbound interfaces).

Fig : LSMW-Process flow diagram

3 Creation of Project Hierarchy

Use the Transaction Code LSMW to go to the initial screen. Create a project, corresponding subproject and object using Edit -> Create entry on menu bar. This is a hierarchy maintained in LSMW for all the data transfer done.

Fig-01: LSMW - create project hierarchy

Create a project, subproject and an object and click on continue. The following screen is displayed with the Project hierarchy details:

Fig-02: LSMW- Initial screen

Once the project Hierarchy is being created, an enumeration of steps for data migration is displayed as shown in Fig-03 below.

This can be changed depending on the requirement of the user. For this “User Menu” tab in the tool bar needs to be clicked and all the necessary steps required for data transfer need to be selected.

Fig-03: LSMW initial screen with user menu for selection of various steps.

4 Step by Step Process for uploading BP master data: The screenshot as in Fig-04 displays the fourteen steps required for loading Business partner data along with their relationships:

Fig-04: Fourteen steps involved in LSMW

The following pages describe each of those fourteen steps and key points to be remembered in each step.

4.1 Maintain Object Attributes In this step a Recording needs to be created (using GOTO -> Recordings overview in menu bar as shown in Fig-05) using Transaction code BP.

Fig-05: Create Recording.

Once recordings overview is clicked the following screen as in Fig-06 will be displayed. Enter a name and description to the recording.

Fig-06: Enter details for the Recording.

Enter the transaction for which the recording is to be done as shown in Fig-07

Fig-07: Transaction BP has been entered.

Here the Business partner category needs to be chosen, under which the customers should be created. Click on Organization as shown in Fig-08:

Fig-08: Click on Organization

Select a Grouping and a Business Partner number in that Grouping and the role under which the customers needs to be created. Enter all the necessary details for business partner that needs to be loaded from the flat file:

Fig-09: Shows Business partner number, Grouping and Role and other details entered. “External Grouping for loading the Customers and Accounts” has been used.

Maintain relationships for the Business partner, as shown in fig-10 if relationships also need to be mapped from flat file.

Fig-10: Displays three Relationships of BP number 1100.

Once all the details have been entered save the Business Partner and click on back icon to go to recording that we created.

Click on the fields displayed in orange color to change the name and default value of the fields. And let the other fields remain same whose values need to be defaulted to existing values.

Fig-11: Displays the first screen of Recording ZRECORDC

Fig-12: Displays the second screen of Recording ZRECORDC

Fig-13: Displays the third screen of Recording ZRECORDC asking details for relationships.

Now once recording is done, this is the first step of LSMW menu where the way or method of Import needs to be decided. There are generally four choices:

1. Standard Batch/ Direct Import Method

- Direct insertion of data through Batch input programs.

2. Batch input Recording method

- In this method a Recording of the transaction needs to be created which is later run as a Batch input Session.

3. Business object Method (BAPI)

- Here the BAPI takes care of the data conversions and updating any database table. So the function module is responsible for the import of data into the system.

4. IDoc (Intermediate documents)

- Here the data is written into an IDoc and passed to the LSMW to get it imported into the system.

However This Document discusses the import of data through Batch input Recording Method.

Fig-14: Choose the “Batch input recording” radio button and give the name of the recording that has been done earlier. Then save the object attributes.

The LSMW system has to have the prior knowledge of what kind of data it is getting from the source that has to be imported into the system. For this reason the following three steps are very important that describe the structure of the files that has to be imported.

4.2 Maintain Source Structure Go to main menu in LSMW as shown in Fig-04 and click on second step: Maintain Source Structure and the following screen as in Fig-15 will be displayed:

Click on create icon, enter a name and description to the source structure and click on continue. Then save the source structure and click on Back icon on the top of the screen.

Fig-15: Entering details of source structure

4.3 Maintain Source Fields

Go to LSMW Menu screen as shown in Fig-04 and Go to Third step: Maintain Source Fields.

Select the source structure that was created and click on Table maintenance as shown in Fig-16

Fig-16: Maintain Source Fields

Once Table Maintenance has been clicked, enter Field name, Data type and Length of all the fields under the required structure as it will appear in the input file. Even it is important to keep the sequence of the fields according to their position in the file. Give name to the fields and save it. Fields, that have constant value like Grouping, Role etc need not be maintained in this table and those fields need not be included in the flat file.

Fig-17: Enter details of source fields and save

Generally it is important to keep the data type and size of the fields same as that of the corresponding field in database table. However this might not be possible in all the cases, then the issue needs to be handled through the conversion routines.

4.4 Maintain Structure Relations

Go to LSMW Menu screen as shown in Fig-04 and Go to Next step: Maintain Structure Relations. The following screen as shown in Fig-18 will be displayed. Save it and go to next step.

Structure relations are the mapping between the structures we have declared in the previous steps with the recording done. However the one to one mapping of the fields will take place in the next step. Here only the high level correspondence is shown

Fig-18: Structure relationship

4.5 Maintain Filed Mapping and Conversion Rules

In the previous step the recording is mapped to the structure. There it automatically creates a one to one correspondence with the fields of both the sides and show in this stage as tree structure. Here each source field needs to be assigned to its corresponding target field in the recording side. A simple way to do this is to select the field from recording and press the tab “Assign source field” which will give a list of fields in the source structure and then select the filed that needs to be mapped to field in recording.

Fig-19: Field Mapping-Initial Screen

Fig-20: Field Mapping-Next Screen

To maintain constant value to a field select that field in the recording and click on Constant (Ctrl+F9) Icon as shown in Fig-20 and a constant value can be assigned to that field.

The following fields have been assigned constant values as displayed below:

a. Grouping : 0002(PB Number Account & Customer –External) b. Role : 000000(Business partner-General) c. Time zone: PST d. Relationship category: FBUR001 e. Overview: A

4.6 Maintain Fixed Values, Translations, User-Defined Routines

Here the conversion rules for processing project data need to be defined. The system generates the conversion program from the structure and field relationships as well as the conversion rules. Customization required for migration of data also needs to be specified here. That is, fixed values and translation values can be assigned and definite variants for the conversion rules can also be specified here.

Fig-21: Maintain Fixed Values, Translations, User-Defined Routines

4.7 Specify Files

Once the previous step of mapping each field to the source structure has been done, the next step is mentioning the file path to be selected for importing.

Fig-22: Specify the path for the file etc.

Here apart from the physical path, other attributes of the file that is to be imported also need to be specified. For example if it is a comma separated or tab delimitated file and if the file contains the field name as Start of File etc.

There are other file-paths that can be mentioned, such as the file for imported data, converted data, etc. if necessary we can choose to change the existing file path that has been defaulted.

4.8 Assign Files

Once the file has been specified as in previous step, this file needs to be assigned.

So in this step select source structure and then click on save.

Fig-23: Assign file

4.9 Read/Import Data

Once assign the file has been assigned, next step is to execute the program as shown in Fig-24 to import the data from the file and put in the structure maintained earlier. For reference the test file that is imported is given below. This is a tab delimitated text file with header row. When it s run, the above program gives the output as in Fig-25. However the successful import data can also be seen from the main menu.

Fig-24: Import / Read data

Fig-25: Result of the execution of import program.

4.10 Display Read/Imported Data

Once the data is imported, it can be displayed using this step. Once this step is selected and continue icon is clicked, system would display the following screen where all the imported data can be seen. Each row can be selected to see all the details of each customer.

Fig-26: Display Imported/Read data

4.11 Convert Data

Once the data is imported to the structure then go to the next step in the main menu that is- Generate conversion program, Convert data and display converted data. The first step generates the program that converts the data imported into the structure to the structure of Recording - ZRECORDC. This take care of all the conversion earlier mentioned. This step converts the data executing above program and store it in the filename given earlier. The result is shown as in Fig-27 & Fig 28. Also the converted data can be seen as in Fig-29.

Fig-27: Convert Data

Fig-28: Converted Data

4.12 Display Converted Data

Once the data is converted, all the Converted data can be seen in this step. Once this step is selected and continue icon is clicked, system would display the following screen where all the Converted data can be seen. Each row can be selected to see more details of each customer.

Fig-29: Display of Converted Data

4.13 Create Batch input session

In this step a Batch input session needs to be created. For creating a Batch Input Session, Go to main menu in LSMW as shown in Fig-04 and click on next step: Create Batch input session and the following screen will be displayed. Click on execute.

Fig-26: Intermediate screen showing the file path for creating Batch input Session.

Once execute is clicked, system will display the following screen with the number of transactions (Business Partners) being created.

Fig-26: Intermediate screen showing the number of transactions created.

4.14 Run Batch input session

This is the final step where system processes the session to get all the data upload into the database through the given transaction (here BP- creating a Business Partner). For this it takes to the session over view screen as in Fig-27 and asks about the way of execution whether it should execute in the foreground or in the back ground. So select the line item and click on process icon on top. A new window pops up as shown. Then the type of processing mode needs to be selected. Processing mode Display errors only has been used which would display any errors encountered during creating business partners.

Fig-27: Session overview and selection of Processing Mode.

Once this step is processed, system will upload all the 450 Business Partners as in flat file into the respective database tables.

In this document since BP transaction has been used, so it will create 450 Business Partners in SAP CRM Database tables. To see the Business Partner data updated in the system use Transaction SE16 and follow the steps as displayed in Fig-28, Fig-29 and Fig-30. Now all the business partners along with their relationship data can be seen that have been uploaded into the CRM System using Transaction BP.

Fig-28: Transaction SE16 and enter table BUT000

Fig-29: Intermediate screen asking for certain criteria to display Business partners. Enter the criteria and click on execute.

Step-By-Step Guide for LSMW using ALE/IDOC Method

Business Case:

In Business scenario, it is required to upload the data into R/3 and process the data in the IDOC form only. The data can be migrated to R/3 SAP system using IDOC Generation Method in LSMW. The data to be uploaded can be regarding material, vendor, customer etc. IDOC is the container, which stores the data in structured format and is used to communicate between R/3 systems. IDOC structure includes Status Record for storing status information of IDOC dispatch, Data Record for storing data into segments and its corresponding fields and Control Record has receiver and source system details etc.

This document contains Step‐by‐Step instructions to use LSMW to generate and process IDOC from the data file available. In first part user‐defined IDOC structure is created and required ALE settings are done .In the Second part, this IDOC structure is used in the LSMW IDOC.

Part One: To create IDOC structure

Step One: Run transaction WE31.Create Segment with name ‘ZEMP_SEG’.

Step Two: Input the fields for the segment structure, which would be required in LSMW for mapping purpose.

Step Three: Now, Go to Edit ‐> Set Release, so that you can use this segment in the R/3 system further.

Step Four: Run transaction ‘we30’ and enter IDOC structure name we want to create.

Here, IDOC structure name is ‘ZEMP_IDC’.

Step Five:

(A)Add segment created earlier to this IDOC type ‘ZEMP_IDC’.

The maximum and minimum repetitions can be from 000000000000 to 99999999999.

Choose any number rang as per requirement.

Now, Go back to earlier page and Click Edit‐> Set Release.

(B)Create new Message type in transaction ‘WE81’.

(C) Attach message type and IDOC type with the help of transaction ‘WE82’.

Step Six: Go to transaction ‘SALE’. Click as marked in red color.

Now add two logical system names for sender and receiver ex. IDC64 and IDC87.

Step Seven: Now assign clients to the logical systems created.

Select the client of your current system as per decision to make that system sender or receiver.

After clicking on to Goto->Details , you come to following screen. Input receiver system ‘IDC87’ to client 800.

Here in our LSMW using IDOC method, no need to assign client to sender as we are doing Inbound IDOC Processing (i.e. Receiver side).

Step Eight: Run transaction ‘WE21’ to create File port. Give directory name as the location of your file to be read. Give dummy name for ‘Outbound file’ field.

Step Nine: Run ‘SM59’ transaction to create RFC connection. Please make sure here connection type

is ‘T’ for TCP/IP .

Step Ten: Run transaction ‘WE20’ to create partner profile for partner of receiver system (IDC87) i.e. sender system (IDC64).

Step Eleven: Create process code using ‘WE42’.

After saving this data, you go screen as below to attach function module to the process code. The process code is the representation of the function module for inbound idoc processing.

Step Twelve: Now you can use this process code in the inbound parameters of the partner’s profile.

Part Two:

Following are the steps to be performed on LSMW side.

Step One:

Enter the project, sub-project and Object name for our scenario.

Step Two:

Click the first radio button ‘Maintain Object Attributes’ , execute and enter the message name and IDOC name into the screen as follows.

Step Three:

Click radio button ‘Maintain Source Structures’ and execute to create new source structure as follows.

Step Four:

Click radio button ‘Maintain Source Fields’ and execute to enter the fields in the source structure. Here these fields are same as the fields in segment of the IDOC created earlier.

Step Five:

Click radio button ‘Maintain Structure Relations’ and execute to create relationship between source and target structure. Here target structure is Message type ‘ZEMP_MSG’.

Step Six:

Click radio button ‘Maintain Field Mapping and Conversion Rules’ and execute to create field mapping and a conversion rules between source structure and target structure.

Step Seven:

Click radio button ‘Maintain Fixed Values, Translations, User-Defined Routines’ and execute to assign fixed values to any field, to call user defined routines etc. These activities are not required in our scenario.

Step Eight:

Click radio button ‘Specify Files’ and execute to assign file on the local workstation to the LSMW to read. The file has contents as shown below.

And now we specify the location of file here.

Step Nine:

Click radio button ‘Specify Files’ and execute to specify file to source structure as follows.

Step Ten:

Click radio button ‘Read Data’ and execute to read file from local workstation as per path specified.

Step Eleven:

Click radio button ‘Display Read Data’ and execute to display data just read.

Step Twelve:

Click radio button ‘Convert Data’ and execute to create a file with extension ‘.conv ’.

Step Thirteen:

Click radio button ‘Display Converted Data’ and execute to display the converted data.

Step Fourteen:

Click radio button ‘Start IDoc Generation’ and execute to generate the IDOC from the data provided and structure mapping done earlier in this document. For this purpose, we cam use the

converted file in step twelve. After successful generation of IDOC, below shown message is displayed.

Step Fifteen:

Click radio button ‘Start IDoc Processing’ and execute to process the IDOC by inputting necessary selection parameters.

Step Sixteen:

Click radio button ‘Create IDoc Overview’ and execute to show status and details of IDOC generated. This screen is similar to ‘WE02’ or ‘WE05’ transaction.

Here , as you can see , the status of IDOC is OK (Green color Bubble) and hence confirms successful processing of IDOC.

Step Seventeen:

Click radio button ‘Start IDoc Follow-Up’ and execute to reprocess the IDOC if not posted or generated properly initially.

Step-by-Step Guide for using LSMW to Update Customer Master Records

Note! The screenprints in this article are from IDES Release 4.6. They may differ slightly in other versions.

Call Legacy System Migration Workbench by entering transaction code LSMW. Every conversion task is grouped together as Project / Subproject / Object structure. Create a Project called LSMW_DEMO and a Subproject as CUSTOMERS and Object as CUST_REC as shown in Figure 1.

Figure 1 Conversion Task with Project, Subproject and Object

The main screen of LSMW provides wizard-like step-by-step tasks, as shown in Figure 2. To complete your data conversion, you need to execute these steps in sequence. Once a step is executed, the cursor is automatically positioned to the next step.

Note that these steps may look different depending upon your Personal menu settings. You could make step numbers visible by ‘Numbers on’ icon or hidden by ‘Numbers off’ icon. You can execute a step by double-clicking on the row. Toggle icon ‘Doubleclick=Display’ or ‘Doubleclick=Edit’, makes the step in ‘display’ mode or ‘change’ mode.

Figure 2 LSMW Wizard – initial screen

Step 1: Maintain Object attributes

In this example, you will be updating the customer master records with the help of recording a transaction (XD02). Choose radio button Batch Input Recording and click on the recording overview icon to record the R/3 transaction. Enter the Recording name as XD02_REC, the description as Customer Master Updates Recording, and the transaction code as XD02.

Figure 3 Object type ‘Transaction Recording’

The system calls the transaction code XD02 and prompts you to complete the Change

Customer transaction, as shown in Figure 4. Enter the key customer information (I entered customer number 1000, sales organization 1000, distribution channel 01, and division 00) and choose ‘Sales’ view within ‘Sales area data’. Make changes to these three fields (I entered, sales office 1010, sales group 110, and customer group 01) and save the transaction.

Figure 4 Transaction recording for Transaction Code ‘XD02’

Once the transaction is completed, R/3 records the flow of screens and fields and saves the information, as shown in Figure 5.

Default Values

Field Names

Figure 5 Transaction recording overview

Note that the fields are populated with default values. The values you entered when you recorded the transaction are set by default.

Note that if you have more fields in the recording than needed, you can remove them by clicking

‘Remove Screen field’ icon.

Observe that the transaction-recording process stores field names in a technical format. By pressing the F1 key on individual screen fields and then pressing the F9 key, the system displays technical names. You then can replace the technical names with descriptive names. Double-click on the field RF02D-KUNNR and enter the name as KUNNR and the description as Customer Account Number and remove the default value. (See Figure 6.)

Figure 6 Field attributes

Similarly, double-click on all other fields with default values and make appropriate changes. Once you have made changes, the recording overview screen looks like what you see in Figure 7.

Figure 7 Transaction Recording Overview – with screen field attributes

Save your changes. When you go back to the initial screen, you will see that the initial screen steps have changed. Since you want to import data via the BDC method, the Direct Input and IDoc-related steps are hidden, as they are not relevant.

Step 2. Maintain Source Structures

Give a name and a description to the source structure (Figure 8).

Figure 8 Source Structure

Step 3. Maintain Source Fields

In this step, you need to list what fields are present in the source structure. The easiest way is to

click on ‘Table Maintenance’ icon to enter Fieldname, Type and Length for each field as shown in Figure 9.

Figure 9 Source fields of source Structure

Note that your input file will have four fields as key fields and you need to update three fields in the system.

Step 4: Maintain Structure Relations

Execute a step to ‘Maintain Structure Relations’. (See Figure 10.) Since, there is only one Source and Target Structure, the relationship is defaulted automatically.

Figure 10 Structure Relation

Step 5: Maintain field mapping and conversion rules

Field RF02D-D0310 represents that you chose ‘Sales view’ for the customer Master screen accordingly its value should be set to X. Keep your cursor on field RF02D-D0310 and click on Constant rule icon to choose the constant value of ‘X’.

If your source file already has the field value, you choose rule ‘Source Field’.

Keep cursor on field ‘KUNNR’ and click on ‘Assign Source field’ icon to choose source field CUSTOMER from structure XD02S as shown in Figure 11.

Figure 11 Assign source fields

Similarly, assign ‘Source Field’ rules to the remaining fields.

Once all the fields are mapped, you should have an overview screen as shown in Figure 12.

Figure 12 Field mapping and Conversion rules overview

Step 6: Maintain fixed values, translations, user-defined routines

You can also maintain re-usable translations and user-defined routines, which can be used across conversion tasks. In this case, that step is not required.

Step 7: Specify files

In this step, we define how the layout of the input file is. The input file is a [Tab] delimited with the first row as field names. It is present on my PC (local drive) as C:\XD02.txt. (See Figure 13.)

Figure 13 File attributes

Create an Excel file (Figure 14) with your data and save it as a Tab-delimited text file on your local drive (C:\) and name it XD02.txt.

Figure 14 Source data in Excel file (saved as Tab delimited file)

Step 8: Assign files

Execute step ‘Assign Files’ (Figure 15) and the system automatically defaults the filename to the source structure.

Figure 15 Assign file to Source Structure

Step 9: Read data

In this step, LSMW reads the data (Figure 16) from the source file (from your PC’s local drive). You have the option to read only selected rows and convert data values to Internal format.

Figure 16 Read Data

Step 10: Display read data

This step (Figure 17) is optional. If required, you can review the field contents for the rows of data read.

Figure 17 Display Read Data

Step 11: Convert data

This is the step that actually converts the source data (in source format) to a target format. Based on the conversion rules defined, source fields are mapped to target fields.

Step 12: Display Converted data

Again this is an optional step to view how the source data is converted to internal SAP format (Figure 18).

Figure 18 Display Converted Data

Step 13: Create batch input session

Once the source data is converted in an internal format, you can create a batch session to process updates (Figure 19).

Figure 19 Create Batch Input Session

Step 14: Run Batch Input Session

You can execute the BDC session by Run Batch input session. Executing a batch input session is a standard SM35 transaction for managing BDC sessions. Once you have successfully executed the batch input session,

the customer master records are updated in the system. You can confirm this by viewing the customer master records (XD03).

Note! Browsing thru these 14 steps, you may get a feeling that this is a very lengthy and time-consuming activity. However, for the purposes of demonstration, I have made it detailed. Although it looks lengthy, actually it takes hardly few hours from start-to-finish! After playing around with few simple LSMW scripts, you will find it so easy to change and create more complex ones.

Uploading Material master data using recording method of LSMW

LSMW to Update Customer Master Records with Standard Object

Step‐by‐Step Guide for using LSMW to Update Customer Master Records

Note! The screenprints in this article are from IDES Release 4.6. They may differ slightly in other versions.

As an alternative to using ‘Transaction Recording’, you could also use a standard SAP object to update

Customer Master Records. Business Object ‘0050’ is already pre-defined in the system with standard Batch

Input Interface Program ‘RFBIDE00’.

Create an Object CUST_OBJ within Project as LSMW_DEMO and Subproject as CUSTOMERS as shown in

Figure 20.

Figure 20 LSMW Object with Standard SAP Object

Note! Only steps that are different from the recording method are listed here.

Step 1: Maintain Object attributes

You will be updating the customer master records with the help of Standard Batch Input; therefore, choose radio‐button Standard Batch/Direct Input as shown in Figure 21. Enter Object ‘0050’ for Customer Master records and default method ‘0000’ and click on Save.

Figure 21 Standard Batch/Direct Input Object Attributes

Step 4: Maintain Structure Relations

Sales view of Customer Master is stored in table KNVV. Accordingly, you need to update structure BKNVV. However, in addition, the Standard Object ‘0050’ also requires updates to BGR00, BKN00 and BKNA1 structures. (If you do not maintain Structure relations for mandatory entries, you might get a message such as ‘Target structure BKNA1 needs a relation to a source structure’.)

Even though you don’t want to update any fields in these structures, you need to create a relationship with source structures. In all, you need to create relationship for four target structures.

Create relationship between source structures XD02S with these target structures with icon ‘Create

Relationship’ .

Keep Cursor on these four target structures and click on icon ‘Create Relation’ and structure relations are maintained as shown in Figure 22.

Figure 22 Structure Relation

Step 5: Maintain field mapping and conversion rules

-- Keep your cursor on ‘TCODE’ field and click on ‘Insert Rule’ icon

Figure 23 LSMW Conversion Rules

Choose radio button ‘Constant’ (Figure 23) to enter value ‘XD02’ transaction code.

‐‐ Keep your cursor on field ‘KUNNR’ and click on ‘Assign source field’ icon

Choose source field ‘Customer’ from source structure ‘XD02S’. (See Figure 24.)

Figure 24 Assign Source fields

‐‐ Similarly, choose source fields for Sales Organization, Distribution Channel, and Division. (See Figure 25.)

Figure 25 Field Mapping and Conversion Rules

‐‐ Scroll down to structure BKNVV fields and assign source fields to three fields Sales Office, Sales Group, and Customer Group (Figure 26).

Figure 26 Field Mapping and Conversion Rules

Save and go back to main screen.

Step 12: Display Converted data

When you convert data, LSMW automatically converts into the appropriate structure layouts, as required by Standard program (RFBIDE00). (See Figure 27).

Figure 27 Converted data into multiple structures

Note that if you had only one record in source file, the converted file has four records.

Earlier, creating this input file, so that the standard interface program can read it, was a big nightmare, the primary reason being that it could have multiple record layouts. Even for a simple conversion with one input record, you would have to create this complex file with many record layouts. The advantage of LSMW is that it prepares these multi‐layout files automatically.

Step 13: Create batch input session

Once source data is converted in internal format, you can create a BDC session to process the updates (Figures 28 and 29).

Figure 28 Create BDC Session

Figure 29 BDC Session ‘CUST_OBJ’ created

Uploading Material master data using Direct input method

Differences between LSMW and BDC

Batch Data Communication (BDC) is the oldest batch interfacing technique that SAP provided since the early versions of R/3. BDC is not a typical integration tool, in the sense that, it can be only be used for uploading data into R/3 and so it is not bi-directional. BDC works on the principle of simulating user input for transactional screen, via an ABAP program. Typically the input comes in the form of a flat file. The ABAP program reads this file and formats the input data screen by screen into an internal table (BDCDATA). The transaction is then started using this internal table as the input and executed in the background. In Call Transaction, the transactions are triggered at the time of processing itself and so the ABAP program must do the error handling. It can also be used for real-time interfaces and custom error handling & logging features. Whereas in Batch Input Sessions, the ABAP program creates a session with all the transactional data, and this session can be viewed, scheduled and processed (using Transaction SM35) at a later time. The latter technique has a built-in error processing mechanism too. Batch Input (BI) programs still use the classical BDC approach but doesnt require an ABAP program to be written to format the BDCDATA. The user has to format the data using predefined structures and store it in a flat file. The BI program then reads this and invokes the transaction mentioned in the header record of the file.

Direct Input (DI) programs work exactly similar to BI programs. But the only difference is, instead of processing screens they validate fields and directly load the data into tables using standard function modules. For this reason, DI programs are much faster (RMDATIND - Material Master DI program works at least 5 times faster) than the BDC counterpart and so ideally suited for loading large volume data. DI programs are not available for all application areas. LSMW is an encapsulated data transfer tool. It can provide the same functionality as BDC infact much more but when coming to techinical perspective most the parameters are encapulated. To listout some of the differences :

• LSMW is basicaly designed for a fuctional consultant who do not do much coding but need to explore the fuctionality while BDC is designed for a technical consultant.

• LSMW offers different techinque for migrating data: Direct input ,BAPI,Idoc,Batch input recording. While bdc basically uses recording.

• LSMW mapping is done by SAP while in BDC we have to do it explicitly . • LSMW is basically for standard SAP application while bdc basically for customized application. • Coding can be done flexibly in BDC when compared to LSMW

Steps to copy LSMW from one client to another

LSMW’s can be copied from one client to another client by using the Export and Import option.

The steps are detailed below.

Export Project

In the initial screen of the LSMW, select Extras Export project. This first displays the structure

tree of the selected project. Via Select / Deselect you can select whether the entire project or parts

of the project are exported. Then select Export. The program then creates an ASCII file.

The selected elements are exported together with their documentation.

Import Project

The exported mapping and rules can be imported into another SAP system by using Import Project

option.

On the selection screen, select Extras ‐> Import. The program then prompts you to enter the name

of the PC file. The file is imported and the contents are analyzed. After the analysis, a list of the

subprojects and objects found is displayed.

You can now mark the objects to be imported. Project data existing already are check‐marked.

They are overwritten by the import.

You can prevent a project already existing in the target system from being overwritten by using

function "Import under different name".

Modifying BAPI to fit custom requirements in LSMW

A Typical Business Scenario:

Consider a scenario where the existing BAPI function module doesn’t cater to your needs and you

need to make some changes to the code. You can take a copy of the BAPI function module to

achieve the functionality. In this case we also need to take a copy of the Business object and the

steps are as follows.

1. Copy the original function module and make necessary changes 2. Take a copy of the Business object and assign the new function module to the corresponding

method. 3. Create ALE interface. 4. Create Partner Profile

Consider the below example for detailed explanation of all the steps required.

Example:

Materials can be uploaded by using a BAPI function module BAPI_MATERIAL_SAVEREPLICA. The

corresponding business object is BUS1001006.

Consider a case The Material Upload LSMW’s that can be created using a BAPI function module

(BAPI_MATERIAL_SAVEREPLICA) for creating different material views. Now there is a requirement,

which demands for some changes in the function module. Then the following steps are to be

implemented.

Business Object:

1. Copy the original function module BAPI_MATERIAL_SAVEREPLICA as

ZBAPI_MATERIAL_SAVEREPLICA. Make necessary code changes to the function module

code.

2. Copy the Business Object BUS1001006 as ZMATERIAL using the transaction SWO1 as shown

below.

3. Now we need to include our custom function module (ZBAPI_MATERIAL_SAVEREPLICA) in the SAVEREPLICA method of the business object as shown below.

4. Generate and Release the Business object (ZMATERIAL).

Generate ALE Interface:

5. Goto transaction BDBG to generate ALE interface for the BAPI. Create the interface as shown below.

6. The message type, IDOC type and the inbound function module are created.

LSMW:

7. Go to transaction LSMW and on the initial screen, click on SETTINGS iDoc Inbound Processing. Maintain the Port and Partner Profile by entering the Port and Partner number and Partner Type.

Step22: Select step13 ‘Start Direct Input Program’ and execute.

Click ENTER.

Validations in LSMW

Requirement: Validation in LSMW. Here we are taking a simple example to change the customer telephone number. Do the validation in LSMW to check whether the provided customer is valid or not. We will handle the Validations in 5th step (Maintain field mapping and conversion rules) of LSMW. If the customer is invalid collect the record to the error internal table and skip the further processing of the record. Download all the error customers into an excel file once the conversion of the all the customers is done. This example mainly will help you to write the custom code in LSMW.

Create the Project, Subproject and Object in the LSMW Transaction.

1. Maintain Object Attributes

Do the recording to change the customer telephone number.

2. Maintain Source Structures

Create the source structure - CUST_DETAILS

3. Maintain Source Fields

Maintain the source fields as per the input file. Here we are taking only Customer and Telephone number as our flat file contains only those two fields shown blow.

4. Maintain Structure Relations

5. Maintain Field Mapping and Conversion Rules

We will do the validation in this step. Execute this step. Go to the change mode.

Click on the button (layout) and select all the check boxes.

Double click on Global Data (this block is like Global data in normal ABAP programs), will get an ABAP editor. Declare the required fields and Internal tables here as shown below.

Validate the customer:

Double click on BEGIN_OF_TRANSACTION block (this block will trigger for every new transaction), and write the validation code as shown below.

We can validate the given customer by checking the table KNA1. If the customer is invalid, then append the Customer to the error internal table with appropriate message. Skip further execution of the record using the Global function skip_transaction (Insert->Global Function-> skip_transaction). This statement will skip the current record and goes to the next record.

Download the Error records:

Double click on the END_OF_PROCESSING block (this block will trigger after conversion of all the transactions), and write the code to download and display the error records as shown below.

The error records will download to the specified file path when we execute the convert data step and same will be displayed.

11) Further continue with the processing (Create batch input session and Run batch input Session) to update the valid customers.

Uploading long text for Material Master 'Purchase Order Text"

Requirement: Loading the purchasing long text for the given materials.

The flat file in our example contains the long text for multiple materials. The header record contains the material information (Material Number and Text ID) and is identified by the starting character ‘H’. The item records contain the long text to be uploaded for the material and the starting character ‘I’ identifies the record. See the screenshot below:

Create a Project, Subproject and Object in the LSMW transaction

1. Maintain Object Attributes

Select the standard direct input method

Object - 0001

Method - 0001

2. Maintain Source Structures

Create two structures one for Header and one for Item. The item structure will be at lower level for the Header

3. Maintain Source Fields

Define the fields as per the flat file structure. In both the structures the first field must be identifier. Create the identifier field of character 1 and specify the identifying field content 'H' for

header structure and 'I' for item stricture as shown below.

Here the Field LINE of item structure is char 132, so each text line from the input file must be less than or equal to the length 132.

4. Maintain Structure Relations

Assign the header source structure to the Header target structure and Item source structure to Item target structure.

5. Maintain Field Mapping and Conversion Rules

Map the source fields to the target fields

Header mapping

For NAME and ID map the source fields MATNR and TEXID respectively.

For OBJECT and SPRAS pass the constants. To enter a constant value for any field, place the cursor on the field and enter a value by clicking on constant button available in the application toolbar.

Handling multiple recordings in LSMW

This example is related to PO output type creation using batch input method.

In this example, we need to handle more than one recording, because based on message transmission medium screens will change.

In this example, have created two separate recordings when message medium is ‘1’ and message medium is ‘6’ respectively.

1. LSMW project.

2. Maintain object attributes.

Here we need to create two separate recordings one for medium type is printer and one for medium type is EDI as shown below.

Select BACK button and in batch input recording need to select more recordings as shown below.

Here initially only one recording will be displayed, then we need to add second recording manually as

shown below.

3. Maintain source structure as shown below.

4. Maintain source fields.

5. Maintain structure relations as shown below.

6. Maintain field mapping and conversion rules.

Here we need to write code to handle recordings based on Message medium as shown below.
