At what point in the process is the matching BP kicked off?

The matching business process (BP) is initiated upon the submission of the invoice. This step is crucial because it represents the entry of an invoice into the system that needs to be validated against existing purchase orders and receipts before any payment is made.

When an invoice is submitted, the system checks it against the corresponding purchase order and receiving documents to ensure that the details such as quantities, prices, and items match. This matching process helps to prevent discrepancies and ensures that the organization only pays for goods and services that have been correctly ordered and received.

In contrast, the creation of a purchase order is simply the preliminary step of outlining what is being ordered, while the approval of a receipt pertains to confirming that the goods have been received. Final payment processing occurs after the matching has successfully taken place, validating that all necessary conditions have been met. Thus, the correct understanding of when the matching BP is triggered is tied directly to the submission of the invoice, solidifying its central role in the Procure to Pay cycle.
