2lis_12_vcitm delta problem

Helo!

When the status for goodsmv_st changes, the delta fetches new record, but doesn't fetch anti-record for record with previous status to annulate it.

This error doesn't happen for all the changed status records, but I can't identify the reason for those records where this happen.

I also have User-exit for this DataSource, but it only appends vbrp-vbeln data from VBRP table. It works correct, and IMHO shouldn't affect datasource functionality.

Any experience with this, any idea how to solve it?

Tnx Gorazd
