This image is a diagram of a service procurement process in SAP Materials Management (MM). It shows the steps involved in purchasing a service from a vendor, from creating a requisition to making a payment.

The process starts with the requisitioner, who creates a purchase requisition. This document specifies the service that is needed, the quantity, and the estimated cost. The requisition is then sent to the approving authority, who reviews it and approves it if necessary.

Once the requisition is approved, it is sent to the procurement department. The procurement department creates a purchase order, which is a formal agreement with the vendor to purchase the service. The purchase order is then sent to the vendor.

The vendor performs the service and then sends an invoice to the finance department. The finance department reviews the invoice and makes a payment to the vendor.
