SAP Note 26863 - Subcontract order with components in alternative QU

Symptom:

The goods receipt for a subcontract order which contains a component (material to be provided) in alternative unit of measure is rejected with message M7022:
EK quantity withdrawn exceeded by xxx.

Cause and prerequisites

The component quantity booked out in the purchase order history during the goods receipt was posted in the base unit of measure instead of in the alternative unit of measure. As a result, the system checks the quantity to be cancelled in order unit (for example, 1000 G) against the quantity booked out during the goods receipt in base unit of measure (for example, 1 KG). Since 1000 is greater than 1, the system rejects the cancellation.

Solution
Please use transaction MB01 (Goods Receipt for Purchase Order) with movement type 102 if you want to cancel already entered goods receipts.
You can cancel goods receipts entered after you have made the corrections described below with transaction MBST (Cancel Material Document).
