SAP MM (Materials Management) Interview Questions with Answers
1. What is SAP MM and what are its sub-modules?
SAP MM (Materials Management) handles procurement and inventory management. Sub-modules include: Purchasing (PO creation, vendor management), Inventory Management (goods receipt, goods issue, stock transfers), Invoice Verification (matching invoices to POs), Material Master (central data), and Consumption-Based Planning. It integrates tightly with FI, CO, SD, PP, and WM.
2. Explain the Procure-to-Pay (P2P) cycle in SAP MM.
P2P cycle: Purchase Requisition (internal request) → Request for Quotation (vendor bidding) → Purchase Order (formal commitment) → Goods Receipt (MIGO, stock posted) → Invoice Verification (MIRO, three-way match) → Payment (FI posts vendor payment). Each step creates documents that reference the previous one for complete audit traceability.
3. What is the three-way match in Invoice Verification?
Three-way match compares: (1) Purchase Order (what was ordered — quantity, price), (2) Goods Receipt (what was received), and (3) Invoice (what vendor is charging). SAP checks tolerances for quantity, price, and amount differences. Discrepancies block the invoice for payment until resolved. This prevents overpayment and fraud.
4. How does Material Master data work in SAP MM?
Material Master is the central record for all materials. It contains views: Basic Data (description, UoM), Purchasing (vendor data, order unit), MRP (planning type, lot size), Storage (warehouse details), Accounting (valuation class, price), and more. Each view is maintained by different departments but shares one material number. It drives all procurement and inventory processes.
5. What are the different Purchase Order types?
Standard PO (one-time procurement), Blanket/Framework PO (quantity contract over time), Scheduling Agreement (delivery schedule with vendor), Consignment PO (vendor-owned stock at your plant), Subcontracting PO (you provide components, vendor manufactures), Stock Transfer PO (inter-plant transfer). Each serves a different procurement scenario.
6. Explain Goods Receipt processing in SAP MM.
Goods Receipt (GR) is posted via MIGO when materials arrive. SAP updates: inventory quantity increases, material document created, accounting document created (stock account debit, GR/IR clearing credit), PO history updated with received quantity. Quality inspection can be triggered. GR against PO enables three-way matching for invoice verification.
7. What is Vendor Evaluation in SAP MM?
Vendor Evaluation scores suppliers on defined criteria: Price (comparison to market/other vendors), Quality (rejection rates, audit results), Delivery (on-time performance, quantity accuracy), and Service (responsiveness, flexibility). SAP calculates weighted scores to rank vendors objectively, supporting procurement decisions and vendor development programmes.
8. How do you handle Returns in SAP MM?
Returns process: Create Return PO (referencing original PO, movement type 122), post Goods Issue to vendor (MIGO with return delivery), receive Credit Memo from vendor (MIRO). SAP automatically tracks return quantities against the original receipt. Blocking reasons and quality notifications can trigger the return process.
9. What is Batch Management in SAP MM?
Batch Management tracks materials by production lot/batch for traceability. Each batch has characteristics (expiry date, origin, quality grade). Batches enable: shelf-life management (FIFO/FEFO), recall management (trace affected batches), quality tracing, and regulatory compliance. Batch determination rules automate picking the right batch for goods issue.
10. Explain the concept of Valuation in SAP MM.
Valuation determines material prices for accounting. Methods: Standard Price (fixed per period, variances posted separately) and Moving Average Price (recalculated with each receipt). Split Valuation allows different prices for same material by origin/batch. Valuation Area can be plant-level or company-code-level. These prices flow to CO for product costing.
