Materials Management (MM) is a core logistics module in SAP S/4HANA responsible for managing procurement, inventory, and material valuation across the supply chain. It ensures that materials are available at the right time, in the right quantity, and at the right cost, supporting business continuity and operational efficiency. MM integrates tightly with Finance (FI), Controlling (CO), Sales and Distribution (SD), Production Planning (PP), Warehouse Management (WM/EWM), and Quality Management (QM), forming the backbone of enterprise logistics.
In S/4HANA, MM benefits from the in‑memory HANA database, enabling real‑time stock visibility, faster procurement cycles, and simplified data models. The module automates key processes such as purchase requisitions, purchase orders, goods receipts, stock transfers, and invoice verification. These processes ensure compliance, reduce manual effort, and improve collaboration between procurement, warehouse, and finance teams.
