It can be created manually or generated automatically through planning processes.
The basic procurement flow can be:
Purchase Requisition → Purchase Order → Goods Receipt → Invoice Verification
6. What is a Purchase Order?

A purchase order generally contains:
- Vendor details
- Material or service
- Quantity
- Price

- Plant
- Storage location
- Payment-related information
7. What is the difference between PR and PO?
Answer:
| Purchase Requisition | Purchase Order |
|---|---|
| Internal purchasing request | Formal purchasing document |
| Usually created within the organization | Sent to the vendor |
| Used to initiate procurement | Used to order goods/services |
| Does not itself represent a vendor order | Represents an actual purchase commitment |
8. What is Goods Receipt?
Answer: Goods Receipt, or GR, is the process of recording the receipt of materials from a vendor into the organization’s inventory.
When goods are received, SAP updates relevant inventory and accounting information based on the transaction.
A commonly used movement type for goods receipt against a purchase order is 101.
9. What is Invoice Verification in SAP MM?
Answer: Invoice Verification is the process of checking a vendor’s invoice against purchasing and goods receipt information.
A common concept is three-way matching, where the system compares:
Purchase Order + Goods Receipt + Invoice
This helps organizations identify discrepancies in quantity and price before processing payment.
10. What is a Movement Type?
Answer: A movement type is a three-digit code used in SAP to identify different types of material movements.
Examples include:
- 101 – Goods receipt for a purchase order
- 102 – Reversal of goods receipt
- 201 – Goods issue to a cost center
- 261 – Goods issue for a production order
- 311 – Transfer between storage locations
Movement types control how SAP processes and records material movements.
11. What is a Plant in SAP MM?
Answer: A plant is an organizational unit where materials are produced, stored, or managed.
For example, an organization may have different plants for different manufacturing or distribution locations.
A plant is an important organizational structure in SAP MM and is also relevant to other SAP modules.
12. What is a Storage Location?
Answer: A storage location is a physical or logical location within a plant where inventory is stored.
For example, a plant can have separate storage locations for:
- Raw materials
- Finished goods
- Spare parts
- Packaging materials
The structure can be represented as:
Company → Plant → Storage Location
13. What is a Purchasing Organization?
Answer: A Purchasing Organization is an organizational unit responsible for procurement activities.
It negotiates purchasing conditions with vendors and manages purchasing transactions.
A purchasing organization can be assigned to one or more plants depending on the organization’s structure.
14. What is a Purchasing Group?
Answer: A Purchasing Group represents the buyer or group of buyers responsible for purchasing activities.
Unlike a purchasing organization, a purchasing group generally represents the person or team responsible for procurement.
For example, an organization may have separate purchasing groups for raw materials, services, or technical equipment.
15. What is the difference between Purchasing Organization and Purchasing Group?
Answer:
A Purchasing Organization is responsible for procurement at an organizational level, while a Purchasing Group represents an individual buyer or group of buyers.
In simple terms:
Purchasing Organization = Procurement organizational unit
Purchasing Group = Buyer or buying team
16. What is Material Valuation?
Answer: Material valuation determines how the value of inventory is calculated and recorded in SAP.
Materials can commonly be valuated using approaches such as:
- Standard Price
- Moving Average Price
The appropriate valuation method depends on the organization’s business requirements.
17. What is a Release Strategy?
Answer: A Release Strategy is used to control the approval of purchasing documents.
For example, an organization may require different levels of approval depending on the value of a purchase order or purchase requisition.
A typical approval flow could be:
Purchase Requisition → Manager Approval → Department Approval → Purchasing
Release procedures help organizations maintain purchasing controls.
18. What is Source Determination?
Answer: Source Determination is the process of identifying a suitable source from which a material or service can be procured.
SAP can use different sources of supply, such as:
- Vendors
- Contracts
- Scheduling agreements
- Source lists
- Quota arrangements
The objective is to help determine the appropriate source for procurement.
19. How does SAP MM integrate with SAP FI?
Answer: SAP MM and SAP FI are closely integrated.
When certain material transactions occur, accounting documents can be generated automatically.
For example:
Goods Receipt → Inventory/Accounting Update
Invoice Receipt → Vendor Liability/Accounting Update
This integration allows procurement and inventory transactions to have the appropriate financial impact.
20. What is the Procure-to-Pay Process?
Answer: Procure-to-Pay, commonly called P2P, is one of the most important processes in SAP MM.
The typical process is:
Purchase Requisition → Purchase Order → Goods Receipt → Invoice Receipt → Payment
The payment portion is generally handled through SAP FI, while SAP MM manages much of the procurement and goods movement process.
Understanding the P2P cycle is extremely important for SAP MM interviews.
Scenario-Based SAP MM Interview Questions?
Experienced candidates may face questions based on practical situations.
Scenario 1: Vendor Delivered Less Quantity.
Question: A purchase order is for 100 units, but the vendor delivers only 80. What would you do?
Answer: The received quantity should be recorded correctly during Goods Receipt. The remaining quantity can be received later if the vendor makes another delivery, depending on the business process.
Scenario 2: Invoice Quantity Does Not Match.
Question: What happens if the invoice quantity does not match the received quantity?
Answer: The invoice can be subject to verification based on the configured tolerances and business rules. If the discrepancy exceeds the permitted tolerance, the invoice may be blocked for payment until the issue is resolved.
Scenario 3: Goods Receipt Needs to Be Reversed.
Question: What would you do if a goods receipt was posted incorrectly?
Answer: The incorrect goods receipt can be reversed using the appropriate reversal process. For a standard 101 goods receipt, movement type 102 is commonly used for reversal.
