Material management is concerned with planning, organizing, and controlling the flow of materials from initial purchase through operations and distribution. The Materials Management (MM) module in SAP supports procurement and inventory functions. MM consists of master data, transactions, and the procure-to-pay process. Key functions include purchasing, inventory management, invoice verification, and integration with other SAP modules like finance, sales, and production. An SAP MM consultant's roles include configuration, implementation support, and troubleshooting issues.
