SAP MM Explained: The Materials Engine | Material Master, Movement Types, MRP | S2 Ep2

Module 2 of 5 in the SAP Concepts Season 2 deep-dive. MM — Materials Management — the module that tracks every physical good a business buys, stores, moves, consumes, or sells, and translates each of those events into the financial postings FI then records. We met MM briefly in Season 1 Episode 4 (Procure-to-Pay). Now we walk into the module properly: what it stores, how those records are structured, and the single most useful piece of vocabulary a SAP user can carry — the movement type. No transaction codes to memorise. No SPRO walkthroughs. Just the mental model of MM in S/4HANA. What You'll Learn: - What MM is for — the four questions: inventory, valuation, incoming, outgoing - The Material Master — the most-edited record in any SAP system; views (basic data, MRP, purchasing, sales, plant, accounting, costing) - Procure-to-Pay refresher — PR → PO → GR → IR, with vendor master now sitting under Business Partner in S/4 - Movement types — the three-digit verbs of inventory: 101 (GR for PO), 261 (GI to production), 311 (transfer), 601 (GI for delivery) - Valuation — Moving Average Price (MAP, V) vs Standard Price (S); Material Ledger always-on in S/4HANA - MRP — the planning engine; ECC overnight batch vs S/4 MRP Live in HANA - The Fiori star screen — Manage Material, with drill-down across movements, plants, and vendors - What we're not covering — info records, source lists, release strategies, batch management, serial numbers, EWM Timestamps will be added before publish. Key Takeaways: 1. Material Master is the most-edited record. One material, many views — accounting, MRP, sales, purchasing, costing. 2. P2P flow drives the bulk of MM-led FI postings. PR → PO → GR (movement type 101) → IR. 3. Movement types are MM's universal vocabulary. 1xx receipts, 2xx issues, 3xx transfers, 5xx other receipts, 6xx other issues. Every other module reuses these. 4. Valuation: MAP for raw materials (actuals fluctuate), Standard for finished goods (variance analysis). S/4 mandates Material Ledger and parallel-currency valuation. 5. MRP runs the planning. Used to be overnight batch in ECC; now real-time in HANA via MRP Live.
