Source system id assignment?

Hello Friends,

HOw important is source s ystem id assignment to the src system.

My incoming data is failing on "no src system id assignment"....

And I cannot convince my basis to assign a src system id to the src system as the system is in QA and they do not want to make any changes.

I know how it can be done..

What I'm looking from the grp is..

If it is not important how can I uncouple the same in my xfer rules or assign it to constant.

If it is important....wat is a good reason.

Thanks for your time.

-Led

    Hi Led,

    Source system ID is useful when you have multiple source systems and source system specific master data needs to be maintained. E.g. Material M1 from source sys A and Material M1 from source sys B mean different materials. So in the Compounding tab of InfoObj, you can set the flag "MAster data locally for source sys". BW will add char 0SOURSYSTEM as the compounding char.

    Now when you load the data for this char, sys automatically reads the 2 char source sys id and updates the compounding char 0SOURSYSTEM.

    Now if you have the scenario explained above then you must maintain source sys id.

    Hope it helps.

      Hi,

      If in BW you have master data that is local to the source system, you can compound the relevant characteristics to the characteristic 'source system ID'. In this way you can separate identical characteristic values that specify different objects in different systems. You can find details about this in Note 0184948.

      If you do not do this an error will occur when you load mastser data for the characteristics that use 'source system ID' as attribute or in compounding. This is because in a data transfer, the assignment of the source system to a source system ID determines the value to be updated for the characteristic 'source system ID'.

      (The above information is given by SAP by F1 help in 'Maintenance of Source system Ids')
