Welcome to the SAP ERP Purchasing WIKI!

SAP ERP Purchasing is part of Materials Management (MM). It handles external procurement of materials and services, determination of possible sources of supply for a requirement identified by the materials planning and control system or arising directly within a user department, and monitoring of deliveries from and payments to vendors. It communicates with other modules such as Controlling (CO), Financial Accounting (FI)  and Sales and Distribution (SD) in the SAP System to ensure a constant flow of information.
