O-6Mapping Request MPYC-… = CLOSED (closed automatically)Every Request line reaches Remaining = 0 after the linked Slip is approved
O-7Exception: Slip stays APPROVED · mapping and stock unchangedThe cancel is blocked because goods on the Pallet BC moved in a later transaction, or the record already has a later action on another screen
