The process starts when the specialist department records a requirement request in the system, which is then automatically checked in the SAP system. If the check fails, the requirement request must be generated again. If it passes the check, the requirement request is forwarded to the purchasing department.
The purchasing department checks or corrects the request for the last time. Before the purchase requisition (BANF) is created in the SAP system, the specialist department has one last opportunity to make any changes. If changes are no longer necessary, the BANF is created and the relevant department is notified.
