SAP can compare information such as:

The purpose is to ensure that the organization pays the correct amount for the materials or services received.

Scenario-Based SAP MM Interview Questions
Interviewers may also ask practical questions instead of only theoretical questions. These questions help them understand whether a candidate can apply SAP MM concepts to real business situations.
Scenario 1: Vendor delivered less material than ordered. What would you do?
First, verify the Purchase Order and compare it with the actual quantity received.
The Goods Receipt should be posted according to the quantity actually received, subject to the organization’s business process and tolerance settings.
Scenario 2: Material is not available in stock. What can happen?
Depending on the configuration and business process, material requirements can trigger procurement or planning activities.
A Purchase Requisition may be created manually or automatically through the planning process.
Scenario 3: Invoice quantity is higher than the received quantity. What happens?
SAP’s invoice verification and tolerance settings can identify discrepancies between the Purchase Order, Goods Receipt, and invoice.
Depending on the configuration, the invoice may be blocked for payment until the discrepancy is resolved.
Scenario 4: What happens if the vendor sends damaged material?
The received material should be inspected according to the organization’s quality and procurement process.
Depending on the business scenario, the material may be rejected, returned to the vendor, or placed in an appropriate stock category.
