Synchronize Pay On Code b/w PO and Supplier Site

Hi All,

In our system, we have identified many open POs that doesn't align pay_on_code with that of the Supplier site setting. Is there a proper way to update them with the supplier setting when suppliers are switched from PFR to POI or vice versa?

Once suppliers are switched to PFR from POI, they stop sending invoice copies, so no invoices are created in the system by our business team (Though PO reads Pay for Invoice). This leads to the nonpayment of suppliers.

Also when suppliers are switched to POI from PFR, they will send invoice copies and thus invoices are created in the system by our business team. (Though PO stays at Pay for Receipt).
