In SAP, the PO net price is RM20,188 which is inclusive of the header surcharge and header discount. The information is passed to DSN PO correctly.
The issue happened when supplier create invoice. The invoice amount is RM(20,188 + 200-12) which exceeded the customer's PO total price which is incorrect. Is there any configuration required from Ariba side to create the invoice based on the PO's price?
