Legacy System Migration Workbench (LSMW) is handy tool for data uploads. In most of the big projects there is aseparate development / data migration team is available. However, at times, it would be responsibility of the functionalconsultant to load the data such as vendor master, customer master and asset master etc. It would be real handy for afunctional consultant to know LSMW (at least recording method) and it would help them to successfully complete thetask. Hope this document would help many of our functional consultants, as I am seeing number of questions aroundLSMW.

Give some Unique name for Project, Subproject and Object. Click Create (Shift+F1). Now execute or pressCTRL+F8.

Give the description for Project, Sub Project and Object and say OK. Now execute or press CTRL+F8.

Very much detail, and certainly any beginner is able to redo the same However, it does not really explain the pitfalls, and it ignores the messagesI have seen it to often that people just focus on SAP, but the L in LSMW is about Legacy system,hence the source is very important.you defined the source from SAP, but this just makes the source equal to SAP for easy loading.But usually the source system is quite different to SAP.So it is very important to define the source how the data is defined in the source system.You made all source fields just 60 long, it is convenient, but then you get for all fields in the fieldmapping the info " Caution: source field longer than target field"Because you get this message for any field it actually becomes a useless information, while it isusually very important as it directly tells you that source data may get truncated if you dont care.To be honest, even after 20 migrations I still get source files from the location teams with content thatexceeds the field length in SAP.Often forgotten is the importance of a mapping old number to new number, usually you have tomigrate more than just vendors. you may have to load orders, or open items, info records etc etc. Andfor these jobs you then need this mapping. for 8 test records it might me easy to create such mapping,but what if you have to load 30000? And not to forget that you just create new records, but often you have already some of these vendorsin your system, which would only need to be extended to a new company code.here you need a second recording

Ravi Sankar Venna Sep 10, 2013 4:43 PM (in response to Jrgen L)Thanks Jurgen or your comments.Mostly this document is written to explain how the data can be loaded from excel to SAP by recordingmethod.You are right, there might be cases, where the source system is also SAP, then it may need coding.That is not considered as that may be much for a functional consultant. Much appreciated your complimentary points for this blog. Hopefully, the Community would benefit out of this. Kind Regards,Ravi
