SAP MM (SAP Materials Management)

SAP MM (Materials Management) is a module in SAP ERP Central Component (ECC) that provides companies with materials, inventory and warehouse management capabilities. The primary goal of SAP MM is to make sure that materials are always kept in proper quantities and without shortages or gaps in the organization's supply chain. It also helps supply chain professionals and other SAP users complete the purchasing of goods in a timely and cost-effective way and to be able to deal with day-to-day changes in these processes.

One of the critical modules in SAP ECC, SAP MM is part of SAP ECC's logistics function and plays a vital role in a manufacturer's supply chain. It integrates with other ECC components like Production Planning (PP), Sales and Distribution (SD), Plant Maintenance (PM), Quality Management (QM), Finance and Controlling (FICO) and Human Capital Management (HCM).

Support for SAP ECC is scheduled to stop in 2025, at which point it will be replaced by SAP S/4HANA. It's not clear from SAP how the functions of MM will transition to S/4HANA, although the newer platform has components to address the core issues behind MM.
