As a long-term SAP user, you want to understand the usage of purchase requisitions in the purchase to pay business process as well as the usage of document types, item categories and account assignment for consumable items.
A purchase requisition is an internal document that the purchasing department uses to procure a particular quantity of a material or a service for a particular date.
A purchase requisition can be created directly or indirectly.
Directly means that a purchase requisition is created manually in the department that has the need. Whoever creates the purchase requisition determines which material or service in which quantity, and for which date have to be ordered.
- Indirectly means that the purchase requisition from another component is created automatically. Purchase requisitions can be created automatically in the following ways:
Material requirement planning (MRP)
You can also initiate purchase requisitions from SAP Ariba.
When you create a purchase requisition for materials that have a material master record, the system transfers the data in the material master record to the purchase requisition. You also have the option to select items from a web-based catalog.
You can convert purchase requisitions into requests for quotations (RFQs), purchase orders (POs), or outline agreements.
