We are working on a standardized process when responding to MA64 messages and I am looking for your input.
Currently when we process a MA64 we change the PO price to match the invoice on PO20.1, than on MA66.3 we select “Accept” for PO Unit Cost and Reason Code “PPAI”.
Although sometimes we are unable to change the PO price we still select the Accept and PPAI.
Recently we have been informed by our Accounts Payable department that we are completing our message incorrectly when we are unable to change the PO price. They have stated that in this scenario the MA66.3 should be answered by selecting “Adjust” for PO Unit Cost, the approved amount per unit should be entered in Unit Cost Amount, and to choose “PPAI” for the reason code.
Can someone please clarify what the correct process is?
