Valuation Class is used to link material to GL accounts in financial accounting. In other words, this class defines the accounts that will be updated through goods movements. For instance, raw material may be linked to a different valuation class from the finished good.
26. What is Moving Average Price (MAP)?
Moving average price is the dynamic valuation method whereby the material price will always be updated after each receipt of the goods. The valuation basis in the moving average price is the stock value and the value of goods receipts.

Split valuation is the valuation method that allows one material to be valued differently due to differences in the source, quality, or batch. The same raw material purchased locally may have a different price compared to imported material.

Scenario-Based Common SAP MM Interview Questions
31. What will you do when you have a price discrepancy in the PO and the invoice?
If there is any price discrepancy, SAP will clear that price discrepancy through the GR/IR account. If the price difference lies in the tolerated price variation range in MIRO, the invoice can be posted, but if it doesn’t, then the posting of the invoice gets blocked.
32. What will you do when Goods receipt cannot be posted against the PO?

- Vendor Blocked – check the Vendor record
33. How does SAP MM interface with SAP FI?
SAP MM and FI are interfaced using Automatic Account Assignment. When a Goods Receipt is done, there will be a Debit Posting of the Stock Account and Credit Posting of the GR/IR Account. In Invoice Verification, there will be a Debit Posting of the GR/IR account and a Credit Posting of the Vendor Account.
34. Compare Reservation and Purchase Requisition.
A reservation is an internal document prepared to allocate reserved stock that is available in the warehouse for a particular purpose (production orders, etc.). A purchase requisition refers to documents made to purchase items that are not yet available in the inventory.
