Diagnosis
With the selected final invoice logic the paid down payment requests ofeach transaction of the down payment chain are posted as individualreceivable line items. For these receivable items there arecorresponding offsetting items from the down payment clearing, which isalso automatically generated as a separate FI document at the time ofthe final invoice. These items have the same grouping in the XREF3field and should then be cleared using transaction F.13. Thesereceivable line items should not end up in payment or be paid manually.

Procedure
You must therefore define a payment block for the selected final invoicelogic. All receivable line items that are to be cleared are thenassigned this payment block. We recommend using a payment block thatcannot be removed.
