Question / Problem:
Payment Terms change on post when PO terms are different than Vendor PO terms
There is an issue when a PO has a different payment term than the vendor master. The Process Director document shows the PO payment term until it is posted. When it's posted, it reverts back to the payment terms on the vendor master data. This causes late payments based on the PO.
If posting the same scenario using MIRO, the payment terms are retained from the PO and not set to vendor payment terms. The PO payment terms are also retained when using Perform from Process Director to post the document.
Answer / Solution:
Check SAP Note 2809193, especially if no changes or updates were made to Process Director. You should be able to retrieve this note from the SAP site.
SAP Note 2809193: "You use BAPI_INCOMINGINVOICE_CREATE, BAPI_INCOMINGINVOICE_CREATE1 or BAPI_INCOMINGINVOICE_PARK to create an invoice. The payment term is not transferred from the purchase order."
