45 Infosys SAP MM Interview Questions And Answers 2026 Updated for S/4HANA

Beginner Questions

These cover foundational concepts tested for freshers at Infosys.

1. What is SAP MM?
SAP MM (Materials Management) is a module for procurement, inventory management, and material valuation, integrating with FI, SD, and PP for end-to-end supply chain processes.

2. Explain the procurement cycle in SAP MM.
It starts with purchase requisition (ME51N), converts to purchase order (ME21N), followed by goods receipt (MIGO), invoice verification (MIRO), and payment.

3. What is a Material Master?
A central repository (MM01/MM02) holding material data across views like Basic, Purchasing, and Accounting for inventory and procurement control.

4. What are the main components of SAP MM?
Procurement, Inventory Management, MRP, Invoice Verification, and Vendor Master Data management.

5. How do you create a vendor master record?
Use XK01 transaction with General Data (address), Company Code Data (payment terms), and Purchasing Data (org details) views.

6. What is a Purchase Order (PO)?
A formal document (ME21N) committing to buy goods/services from a vendor, specifying quantities, prices, and delivery dates.

7. Differentiate between Purchase Requisition and Purchase Order.
PR (ME51N) is an internal request for materials; PO is vendor-committed approval of that request.

8. What are movement types?
Codes defining stock movements, e.g., 101 for Goods Receipt, 201 for Goods Issue to Consumption.

9. What is Goods Receipt (GR)?
Posting incoming goods against a PO using MIGO, updating inventory and triggering FI accounting.

10. Explain integration between SAP MM and FI.
MM postings like GR/IV automatically post to FI for account determination (e.g., GR/IR clearing account).

A record (ME11) linking material-vendor data for automatic pricing/conditions in POs, reducing manual entry.

12. Explain Purchasing Organization and Group.
Purchasing Org (T-Code OX08) handles external procurement centrally; Group (OXRM) is a buyer team under it.

13. What is Special Stock?
Stock tied to specific purposes like project (Q), sales order (E), or consignment (K), not unrestricted use.

14. Differentiate PR Document Types.
NB (standard), FO (framework), CON (consignment); each controls release and conversion to PO.

15. What happens during Goods Issue (GI)?
Reduces stock via MIGO/MB1A (e.g., movement 261 for production); updates consumption accounts.

Intermediate Questions

These assess practical configuration and processes, common for 2-5 years experience at Infosys.

16. What is MRP and how is it run?
Material Requirements Planning forecasts needs via MD01 (total planning) or MDBT (single-item); uses lot sizing and safety stock.

17. Explain pricing procedure in PO.
Determined by schema (RM0000), condition types (PB00 gross price), and access sequences based on vendor/material info records.

18. What is release strategy for PO?
Configurable approval workflow (OMGQ) based on characteristics like document type, value, plant; uses classification tables.

19. Describe subcontracting process.
Provide components (movement 541) to vendor via ME2O; post receipt (101) and consume components (543); settle via MRRO.

20. What is consignment process?
Vendor stock in your plant (KI18); post goods issue (201K) when consumed; invoice only withdrawn quantities via MRKO.

21. How does automatic account determination work?
Via config (OBYC/OB41) using keys like GBB/VBR; maps valuation class, movement type to GL accounts.

22. What is Split Valuation?
Allows different valuations for same material (e.g., imported vs local) via MMAM config for quality/condition-based pricing.

23. Explain Stock Transport Order (STO).
Inter-plant transfer (ME21N, UB doc type); shipping (VL10B) and GR (MIGO) without vendor involvement.

24. What is Invoice Verification (IV)?
MIRO matches PO, GR, and invoice for 3-way match; tolerances for price/quantity via OMR6.

25. How do you handle physical inventory?
Create doc (MI01), count (MI04), differences (MI07/LI11), recount (MI10), post (MI20).

26. What is Source List?
ME01 maintains fixed vendors per material/plant for automatic PO sourcing; validity periods enforced.

27. Explain Batch Management.
Activated in material master (MSC1N); tracks units by lot for expiry/quality, split valuation supported.

28. How do you configure Output Types for POs?
Via NACE (application EF); assign to procedures, set condition records for print/email triggers.

29. What is Valuation Class and Category?
Class groups materials for GL mapping (OMSK); Category (e.g., A full valuation) defines method.

30. Describe Returns Process.
Return PO (doc type RE); post return delivery (MIGO 122 movement), then credit memo (MIRO).

Advanced Questions

These target S/4HANA specifics and Infosys scenarios for seniors (5+ years), emphasizing real-time analytics and integrations.

31. Key differences between SAP MM in ECC and S/4HANA?
S/4HANA uses Business Partner (BP) over Vendor Master, mandatory Material Ledger, Fiori apps replacing transactions, simplified tables (no aggregates).

32. Explain Fiori apps in S/4HANA MM.
Role-based UIs like “Manage Purchase Orders” or “Purchase Order Approval” for mobile/real-time processing over GUI.

33. How has MRP evolved in S/4HANA?
Advanced MRP (aMRP) with AI forecasting, decision intelligence; uses CDS views for real-time planning without batch jobs.

34. Describe embedded EWM in S/4HANA.
Integrated warehouse mgmt without separate system; handles inbound/outbound via /SCWM/ apps, leveraging HANA for speed.

35. What are Quota Arrangements?
MEQ1 distributes procurement across vendors by quota (% or fixed); auto-selects in PO based on validity/rating.

36. Explain pipeline handling in MM.
Consignment-like for rented equipment (movement 101R receipt, 201R return); no ownership transfer, valuated specially.

37. How do you configure output determination for PO?
NACE/BRF+ with condition records (MN04); S/4HANA uses BRF+ apps for forms (Adobe/Output Management).

38. What is JIT scheduling agreement?
ME31J for automotive; auto-generates deliveries via JIT calls, integrates with shipping for frequent small lots.

39. Troubleshoot GR not updating stock value.
Check PO price (ME23N), tolerance (OMBG), account assignment, valuation class mismatch, or FI config (OBYC).

40. Infosys-specific: Handling custom developments in MM.
Use BAdIs (e.g., ME_PROCESS_PO_CUST) or enhancement spots for PO validations; follow FS/TS for S/4HANA upgrades.

41. What are CDS Views in S/4HANA MM?
Core Data Services for real-time analytics (e.g., I_PurchaseOrderItem); replace aggregates for Fiori reporting.

42. Explain Central Procurement in S/4HANA.
Hub system manages POs across affiliates; leverages SAP CI for cross-company sourcing.

BRF+ replaces NACE; apps like Manage Purchase Order Output for dynamic forms/channels (SAP S/4HANA 2022+).

44. Troubleshoot blocked invoices in MRBR.
Check tolerances (OMR6), PO variances, duplicate check; release via program or Fiori app.

45. Infosys-specific: MM-Fiori Custom Tile Development.
Extend via SAP Fiori Elements; use RAP for OData services, integrate with MM BAdIs for role-based dashboards.
