Purchasing (MM-PUR)

Instrument used by the purchasing department to procure materials or services.

The standard R/3 system includes the following external purchasing documents:

• Request for quotation (RFQ)
• Purchase order (PO)
• Contract
• Scheduling agreement

In the SAP System, the term "purchasing document" is often restricted to such external documents (that is, documents other than purchase requisitions).

You can use a purchase requisition (an internal document) to notify Purchasing of your requirements of materials and services.
