Diagnosis

In these cases, you cannot choose areversal method where offsetting items are created because you cannot besure that cash discount or payment surcharges will arise for theseoffsetting items in the same amount as for the document to be reversed.

Procedure

If no other reversal method is possible, or the document has alreadybeen archived, the only option left is to post an individual credit memoto the contract account.
