  • Integration of ERP & APO via CIF (Review)

  • CIF Overview

    Core interface (CIF) is the central interface that connects SAP SCM to the existing SAP ECC system environment. Data transfer between the ECC and SCM systems is defined and controlled using the Core Interface (CIF).

    CIF is an integrated part of the ERP system (in SAP ECC 6.0) and also is an integrated part of SAP APO, 5.0.

  • CIF Overview

    CIF enables transferring master data from SAP ERP to SAP APO in one way only, and transferring transactional data in both ways between ERP and APO

    In the Core Interface, the user selects the objects to be transferred to SCM via the integration models.

    Only the planning-required parameters are transferred from the SAP ECC dataset to SAP SCM.

    Technically, the transfer is performed via the queued remote function calls (qRFC).

  • Core Interface (CIF) (Review)

  • APO Core InterfaceData transfer between the ECC and SCM systems is defined and controlled using the APO Core Interface (CIF).

    CIF is the central interface that connects SAP SCM to the existing SAP ECC system environment. It is available to the ECC systems through a plug-in.

    In the APO Core Interface you select the objects that you want to transfer to SCM via integration models.

  • APO Core InterfaceOnly the planning-relevant parameters from the complex dataset of SAP ECC are transferred to SAP SCM.The APO Core Interface is used for both initial data transfer (initial transfer) and change transfer (transfer of data changes) to SCM.

  • Master Data (review)The relevant master data for production planning:

    LocationProductResourcesPPM and PDSQuota arrangement, Set up Group & matrix, and Interchangeability group.

    Resource views:SNP and PP/DS require a different view of the capacity.SNP in time bucketsPP/DS time-continuous capacity

  • Master Data Object

  • Master Data Transferring

  • Transactional Data for Transferring

  • CIF Configuration

    The communication between ERP and APO systems is based on queued remote function calls (qRFC).

    To enable this communication, the user needs to configure the Application Link Enabling (ALE) settings and the parameters for communication (see Figure 25.1)

    The user needs to define the logical systems for both ERP and APO systems

  • CIF Configuration

  • CIF Configuration

    In the ERP system, the APO logical system has to be defined as the target system by assigning the system type and release with transaction code NDV2 and the queue type with the transaction code CFC1.

    The remote function calls (RFC) destination defines the address of the target system and the access data (user for the target system, password).

    The RFC destination has to have the same name as the logical system of the target system and that the name is case sensitive.

  • Integration Models for Data TransferThe integration model is used to specify selection criteria for master data objects and the logical name of the target (APO) system.

    The same integration model can be used to transfer more than one type of object but it is a good practice to use multiple integration models (one per object type) to avoid complex maintenance of the selection criteria.

    When ERP sends orders to APO, the integration models check whether the active integration model exists.

    Integration models are created (T-code CFM1) and activated (T-code CFM2) on the ERP side.

  • Objects of Integration Models Two types of objects:Material dependentsuch as ordersMaterial independentsuch as resources and suppliers.

    Table 25.2 lists some of objects that can be included into integration models and transferred to APO.

  • Objects for Integration Models

  • Master Data Objects in SAP APO and SAP ERP (review)

  • Objects of Integration ModelsWhile creating the integration model, the objects which match the selection criteria, are read in and assigned to the model.

    The integration model is unique in its name, the target system, the application, and its version. The user can freely name the integration model and denotes its application. The target system is selected from the APO system that is defined in the CIF configuration.

  • Objects of Integration Model A new version is generated for the integration model, each time when the user modifies it. The user and the date of generation are part of the version name.

    The transfer of objects is sequence-dependent. For example, plants must be transferred prior to the transfer of work center.

    The transfer of data is triggered by activating the model with the transaction code, CFM2.

  • Decision for Object Transfer

  • Initial and Delta TransferInitial transferDuring the initial transfer, CIF (the currently active version) transfers all objects to APO.

    Delta transferIf the new version is activated (while the older ones still remain active), CIF transfers only new objects (i.e., the objects that are not included in the old version).

    Usually a periodical delta transfer is used for data integration, to reduce the system load.

  • Initial and Delta Data Transfer

  • Master Data IntegrationMaster data is usually one of the most crucial factors for the success of an implementation. Master data in ERP have to have a sufficient quality.Master data must be kept consistent between ERP and APO, otherwise planning will be inaccurate and lead to wrong results.

    Generally strongly recommend to maintain master data in ERP environment.

  • Master Data IntegrationThe master data objects in SAP SCM are not identical to those in SAP ERP.

    During master data transfer, the relevant SAP ERP master data is mapped to the corresponding SAP SCM master data. The SAP ERP system is the owner of most of the master data. Only specific SCM master data (such as transport lanes) that does not exist in SAP ERP is maintained in SAP SCM.

  • Master Data Transfer Strategies

  • Transactional Data IntegrationThe transfer of transactional data is working two ways, from ERP to APO and from APO to ERP.

    From ERP to APO, there is usually one initial upload and from then onward a continuous online transfer of data changes.

    From APO to ERP, the default setting for the transfer is immediately for PP/DS order and periodically for SNP orders.

    ***********The data generated or changed by SAP APO in Supply Network Planning (SNP) or Production Planning and Detailed Scheduling (PP/DS) is transferred to SAP R/3. This operation is called the publication of planning results. There are two types or publication in SAP APO: Direct publication and periodic publication. You can choose between the two by using transaction /SAPAPO/C4*Publication in SAP APO: For the transfer of transactional data from SAP APO to SAP ERP it is necessary to maintain the distribution definition per publication type (e.g. in-house production) and location to SAP ERP system.Publication in SAP APO: For the transfer of transactional data from SAP APO to SAP ERP it is necessary to maintain the distribution definition per publication type (e.g. in-house production) and location to SAP ERP system.Publication in SAP APO: For the transfer of transactional data from SAP APO to SAP ERP it is necessary to maintain the distribution definition per publication type (e.g. in-house production) and location to SAP ERP system.Publication in SAP APO: For the transfer of transactional data from SAP APO to SAP ERP it is necessary to maintain the distribution definition per publication type (e.g. in-house production) and location to SAP ERP system.
