How to Answer Scenario Questions

Use a simple answer format: business problem, SAP document, master data involved, configuration area, possible cause and resolution approach. For example, if a wrong G/L account is picked, mention valuation class, transaction key and OBYC instead of giving a generic answer.

Sample Real-Time Answers

Invoice is blocked in MIRO. What will you check?

Check whether the invoice quantity and price match the PO and goods receipt. Review tolerance limits, tax details, delivery costs and PO history. If the invoice is above allowed tolerance or goods receipt is incomplete, SAP may block the invoice for review.

Wrong G/L account is selected during goods receipt. What may be wrong?

Review automatic account determination. The issue can be related to valuation class in material master, transaction key, chart of accounts, valuation grouping code or OBYC assignment. The answer should connect MM movement to FI posting logic.

Stock is not visible after goods receipt. What will you verify?

Check the movement type, plant, storage location, material document, stock type and whether the GR was reversed. Also verify if the material was posted to quality inspection or blocked stock instead of unrestricted stock.

Preparation Checklist

• Practice PR, PO, MIGO and MIRO document flow.
• Understand movement types and stock categories.
• Know material master fields used in purchasing and accounting.
• Explain valuation class and OBYC in simple language.
• Prepare at least two real-time support scenarios.
• Connect every answer to business impact.

Conclusion

SAP MM interview preparation should focus on process understanding. PR, PO, MIGO, MIRO, movement types, valuation, inventory and MM-FI integration are connected. The more clearly you explain the connection, the stronger your interview answers become.
