What MM does
MM handles the full procurement cycle, purchase requisitions, purchase orders, goods receipts and invoice verification, and manages inventory (stock quantities and valuation) across plants and storage locations. It ensures the business has the materials it needs, procured through controlled processes.
Key processes and objects
- Purchase Requisition & Purchase Order: requesting and ordering.
- Goods Receipt: receiving stock (updates inventory and posts to FI).
- Invoice Verification: matching invoices to POs/receipts.
- Material Master & Vendor (BP): the key master data.
- Inventory Management & valuation.
How it integrates
MM is central to procure-to-pay: goods receipts and invoice verification automatically post to FI (accounts payable, inventory value) and to CO. It integrates with PP (materials for production) and SD (stock for sales), making it a hub of the supply chain.
Learning it
Learn MM by following its end-to-end process, its master data, its configuration (in SPRO), and its integration points with finance and neighbouring modules. Hands-on practice in a training system is essential.
Common pitfalls
- Learning screens, not the end-to-end process.
- Ignoring the finance integration that every logistics module has.
- Skipping master-data setup that the process depends on.
