The user complains that the item 1 of 4 items in one document type AB, although it had the Credit memo and the Payment Ref. fields filled with the invoice number 9054525892 it was not cleared by the customer payment. They usually work with an automatic process to clear the documents.
The customer pays an amount (he already knows the net amount) for the bank and by the return file, according to the original invoice it makes the clearing if all the documents have the same due date and Payment reference correctly filled.
I would like to know why the item 1 of the document type AB was not considered even with the paymennt reference field filled.
Does SAP recognize the payment reference just if it is a document type debit 40 / credit 11 or is it smart enough to find an ITEM inside a document to clear just it?
I believe the user created a wrong document to give a discount.... but I would like to know how SAP works with the payment reference field.
