SAP Note 22736 - GR reversal for SC order: Qty proposal for component

Symptom:

Key word: Subcontracting
During a reversal or return delivery of a goods receipt for a subcontract order (with transaction MB01), the quantity proposed by the system on the item selection screen is overwritten by the user. However, the subsequent quantity proposal of the system for the "material to be provided" items (components) corresponds to the originally proposed quantity of the reversal of the goods receipt (or return delivery). A proposal with the corrected quantity would have been correct though.

Cause and prerequisites

Program error.
