I have a generic datasource on KNVP table. Sometimes the Ship-To (KNVP-PARVW="WE") record is deleted from the KNVP table. When this happens, I need to set the BW attribute values to initial for the deleted records. Since the record no longer exists in the KNVP table, the record will not be transferred to BW anymore. Is executing a self-update in BW to first set all the attribute values to initial and then execute the update for the datasource the best process to set the attribute values to blank for the deleted KNVP master records?
