I am facing issue while extracting data from ByD to BW. In error message only, "Unexpected error occurred, Error in Source system". is shown.
On closure note we found 1 field was added in ByD datasource. We replicated the same in BW but still the same error message appears.
Has anyone ever faced this issue?
Did you try to first drop the subscription from BW side?Delete the inits in BW and trigger it again. In ODQMON you need to see (from source side, BYD) if there are failed requests for example. You may test the extraction from ByD side by running RODPS_REPL_TEST to determine whether the issue is in the extraction in Source System or in arriving to BW (narrow down..). In this page you can see the instructions on how to run it. If you get further doubts feel free to ask too: https://wiki.scn.sap.com/wiki/display/BI/Replication+test+with+RODPS_REPL_TEST
