Creating a Delta on External MSS System

Posted on May 21, 2004 at 12:43 PM 11 Views

We have connected an external MSS System to BW 3.0B as a source system and datasouce is generated on the basis of a view having date field in MSS system. Looking for guidelines to setup delta extraction mechanism for this data source.

Thanx & regards,

    Hi Ravindra

    We had a similar problem. If I'm right you have two possibilities to do this. The first way is, you have in the source system a timestamp that you can use in the InfoPackage for selection of the new/modified data.

    If the other case you can maybe use an ODS object instead. There you can define if data is new or for update. The BW creates then automatically a delta mechanism for loading the data into data targets (see Online-Docu http://help.sap.com/saphelp_bw30b/helpdata/en/f9/45503c242b4a67e10000000a114084/frameset.htm)

    Hope this helps.

    Regards,

    Hansjörg
