1. How does invoice blocking work in SAP MM?
Ans:
An invoice may be blocked when it fails configured checks or exceeds permitted tolerances. The user reviews the price, quantity, and receipt information, investigates the discrepancy, and follows the approved release or correction process.
2. What are planned delivery costs in purchasing?
Ans:
Planned delivery costs are additional expenses entered during purchasing, such as freight or insurance. They are maintained in the relevant purchasing conditions and processed according to the configured accounting and valuation rules.
3. How would you investigate a difference between invoice value and purchase order value?
Ans:
- Compare the purchase order with the supplier invoice.
- Check quantity, unit price, tax, and delivery costs.
- Review approved order changes and invoice tolerances.
- Coordinate corrections with purchasing or finance.
4. What is account determination in SAP MM?
Ans:
Account determination identifies the relevant general ledger accounts for inventory and procurement-related postings. It depends on factors such as valuation settings, transaction keys, and configuration. Correct account determination helps ensure that material transactions generate appropriate financial entries.
5. How would you troubleshoot an incorrect inventory valuation?
Ans:
I would review the material's valuation data, price control, recent goods movements, and invoice postings. I would also check the related accounting documents and system configuration. Any correction should be made only after the cause is identified and the required authorization is obtained.
6. Why are transport requests important in SAP MM projects?
Ans:
Transport requests move approved configuration or development changes between SAP environments. They support controlled deployment, change tracking, and testing across development, quality, and production systems.
- Document the change and its purpose.
- Complete the required testing and approvals.
- Verify the outcome after deployment.
7. How would you test a new purchasing workflow?
Ans:
I would prepare test cases covering normal purchasing scenarios, approval steps, and common exceptions. I would execute the workflow, compare actual results with expected outcomes, document defects, and retest corrections before business acceptance.
8. What is the role of valuation class in SAP MM?
Ans:
A valuation class groups materials for automatic account determination. It helps SAP select appropriate general ledger accounts for relevant inventory transactions based on the configured valuation and transaction rules.
9. How would you support users during an SAP MM rollout?
Ans:
- Explain the new purchasing and inventory procedures.
- Help users understand transaction errors.
- Provide approved training material and examples.
- Record recurring issues and share feedback with the project team.
10. What should be checked after an SAP MM system upgrade?
Ans:
I would validate important procurement and inventory scenarios, including purchase order creation, goods receipt, invoice verification, and relevant integrations. I would review error logs, test key business processes, document issues, and confirm that critical activities work as expected.
