The purpose of the NotifyPayable is to transmit data to create a payable open item in a payables application from the purchasing information generated in a purchasing application. The NotifyPayable may also update the General Ledger, depending on the specific architecture of the financial applications.

The scope of the NotifyPayable indicates that the supplier’s invoice is ready to be paid and has already been approved before the information moves to the accounts payable application. An approved invoice is also known as the voucher. OAGIS will define the scenario of invoices that get matched within the accounts payable application in a separate Business Service Request later.

Some financial applications have the general ledger and accounts payable databases tightly integrated where updates to the accounts payable application are automatically reflected in the general ledger balances.
