SAP Note 25753 - Balance on GR/IR clearing account for OPUn

Symptom:

For an order item with order price unit (OPUn), the GR/IR clearing account is not cleared although the delivered quantity equals the quantity invoiced in the order unit.

Cause and prerequisites

This problem can occur if an invoice is posted before the goods receipt. The system valuates the subsequent goods receipt in accordance with the quantity in the order price unit. If the delivered quantity and quantity invoiced are now different from each other in the order price unit although the delivered quantity and the quantity invoiced are identical in the order unit, this problem occurs.

Solution
Please carry out the repair described below in program LMBGBFSU.
Then cancel the last goods receipt with transaction MBST afterwards for every affected order item for which the delivered quantity and the quantity invoiced are identical in the order unit. Directly after this, cancel the resulting reversal document with transaction MBST. After this, the order item in question has no balance on the GR/IR clearing account any more.
For the order items where the delivered quantity and the quantity invoiced are not identical in the order unit, no action is necessary. The balance on the GR/IR clearing account is automatically corrected by the following goods movements or invoices.
