Only one business partner can be written off during resubmission

generate a write-off document for several business partners at the same
time. Only one business partner is allowed in the write-off document
for resubmission.

System Response

You cannot save the write-off document.

How to fix this error?

Enter one business partner for the write-off documents, by
defining a specific business partner for the selection specifications
so that only documents for the one business partner are selected.
Or only select open items for the write-off that have the same business
partner assigned to them.
