Ask the BW Expert: Why Do My Delta Updates from CO-PA to BW Fail?

  • by Frank Bulacher, Manager of SAP CH, Alstom Switzerland

The key to a successful delta update is the proper creation of the CO-PA DataSource. Here's how it's done.

Dear BW Expert,
We recently uploaded all our CO-PA data to SAP's BW without a hitch. Delta updates, however, have been a problem. The job always terminates, and a message says we have an error in the source system. This is confusing since it worked for full updates. We are on 4.6C in R/3 and have BW version 2.1C. Please help.
