Processing Purchase Requisition in ERP 

Purpose

You can use this business process to process purchase requisitions in ERP. A purchase requisition is a demand that is released to the purchasing department. The demand can be created as follows:

●      Automatically, for example as result of a material requirement planning (MRP) run, or by assigning components or services to a maintenance or production order

●      Alternatively, the purchase requisition may be:

○       Entered manually

○       Transferred from another system, for example from a shopping cart that has been approved:

■       In an Enterprise Buyer (EBP) classic scenario

■       From Supply Network Planning (SNP) or Production Planning and Detailed Scheduling (PP/DS) of a Supply Chain Management (SCM) module

The accounting data is assigned and checked during processing of the purchase requisition. Sourcing, including initiating a request for quotation (RFQ) process, can be executed based on a purchase requisition as well as assignment of documents.

It is possible to establish approval processes for purchase requisitions. For purchase requisitions with long life cycles, a change management differs between several versions.
