PO Change Orders - Fixed Price Service Lines/PO's

 Hi All, 

We have an issue where the business are matching PO's (primarily with Fixed Price Services lines) to invoices, which causes issues when the business try to revise the PO to meet the over bill amount as our PO workflow goes into error. 

I have already seen Doc ID - 1331770.1 covering that this is standard functionality for Oracle to allow closed PO shipments to be matched to an invoice but I am more interested in the expected/routine business process i.e. should AP match to the PO before opening & revising the PO amount to meet the expected invoice amount? Or should the request be sent to the procurement team to increase the line amount for the AP team to match?
