I'm getting a log message "Source of supply (5300001019) not in source list (WCA0027/1001) despite source list req." when we run the SNP production planning (cdpsb0).
we are using APO and created an external procurement relationship based on the source list in ECC. i tested with 2 setups: with check and without check on the material master - purchasing (source list). I'm getting the same error.
whatelse should i check?
