1. How does SAP MM handle the procurement of external services?
Ans:
SAP MM supports service purchasing through documents that describe the required work, quantities, values, and account assignments. Depending on the process, a service entry sheet records the work completed by the supplier. After the required review and acceptance, the supplier invoice can be verified and processed under the organisation's purchasing procedures.
2. Why is a service entry sheet required for service procurement?
Ans:
A service entry sheet documents services performed against an applicable purchasing document. It records details for review and acceptance by authorised personnel. Once approved, it can support invoice verification and provide evidence that the billed services have been recorded and accepted according to the agreed requirements.
3. What would you verify when SAP rejects a goods receipt transaction?
Ans:
- Read the error message and inspect the purchase order status.
- Validate the material, plant, storage location, and quantity.
- Confirm that the purchase order item permits goods receipt.
- Review posting periods and applicable delivery restrictions.
- Resolve the cause and verify the posted material document.
4. How can materials be returned to a supplier through SAP MM?
Ans:
A return-to-vendor transaction records materials sent back because of damage, quality issues, incorrect delivery, or another approved reason. Depending on the process, the return may reference the original purchasing document or goods receipt. Correct processing updates stock records and creates the documentation needed for supplier coordination and financial follow-up.
5. What information does a material document contain?
Ans:
A material document records an inventory transaction or goods movement in SAP. It includes details such as the material, quantity, movement type, organisational assignments, and posting date. It provides a traceable history for stock analysis and may be linked to an accounting document when the transaction has a financial impact.
6. How would you troubleshoot a failed transfer between two plants?
Ans:
I would check both plant assignments, material extensions, available stock, and the transfer process being used. I would inspect the stock transport order or relevant transfer document, delivery status where applicable, and system messages. After correcting missing data or configuration issues, I would verify that the goods issue and receipt are recorded correctly.
7. How do movement types influence goods movement transactions?
Ans:
Movement types identify the category of inventory transaction and control how SAP processes stock changes. They influence quantity updates, stock categories, and relevant accounting effects. Selecting the correct movement type ensures that goods receipts, goods issues, transfers, and other material transactions follow the intended business process.
8. Which SAP documents help analyse a material's purchasing history?
Ans:
I would examine purchase orders, goods receipt records, supplier invoices, and purchasing information records. I would compare historical prices, quantities, suppliers, delivery dates, and ordering patterns. Reviewing this information helps identify procurement trends, assess supplier performance, and make informed purchasing decisions.
9. How does SAP MM work with Quality Management during goods receipt?
Ans:
SAP MM can integrate with Quality Management to support inspection of incoming materials. Depending on the configuration, a goods receipt can trigger an inspection lot and place the stock in quality inspection. After inspection results and the usage decision are recorded, the material can be released, restricted, or processed according to the quality requirements.
10. How would you investigate a recurring SAP MM issue in production?
Ans:
I would document affected transactions, error messages, business impact, and steps to reproduce the issue. I would examine relevant master data, configuration, and document flow to identify the cause. After an approved correction, I would test the process, record the resolution, and recommend preventive checks where appropriate.
