A Guide to SAP MM

Materials Management (MM) is part of SAP ERP. It helps firms buy goods, check stock, and keep track of materials.

For example, a factory needs raw goods to make its products. MM helps staff place orders, track stock, and check vendor bills.

It has five main tasks: buying goods, checking stock, keeping material records, storing vendor data, and checking bills.

MM also works with other SAP modules, such as Finance (FI), Sales and Distribution (SD), and Production Planning (PP). This helps teams share data and work as one.

SAP MM Interview Questions for Freshers

These Interview Questions for Freshers cover basic MM terms and tasks. They can help new learners build a strong base.

1. What is MM, and what are its main functions?

MM stands for Materials Management. It helps firms handle the buying, storage, and tracking of goods. In simple terms, it keeps the material flow organized.

It deals with purchasing, inventory control, material master data, and invoice validation. For instance, a company requires 100 computers. MM will assist in ordering them, when they will be received, and also tracking the inventory.

2. What is the organizational structure in MM?

The MM organizational structure shows how a firm arranges its plants, storage areas, and purchasing teams. It provides a clear understanding of how materials are managed.

It includes the client, company code, plant, storage location, and purchasing organization. A plant could be a factory, for example. A storage location tells where the goods are kept inside that plant.

3. What is master data in MM?

Master data remains in the system and gets reused when required. It contains essential data used for all material and procurement activities. It includes material master, vendor master, purchasing document, and source list. 

4. What is the procurement process in MM?

The procurement process explains how a firm buys goods or services. It usually starts when someone raises a purchase request.

The buyer subsequently makes a purchase order which is sent to the supplier. Upon receiving the products, the company makes an entry of the same and verifies the invoice, after which the accounting department makes the payment.

5. What is the difference between material master and purchasing information record?

Material master stores general information about a material. This includes such data as name of material, units of measure and stock information. Purchasing information record stores purchasing information about certain material from certain suppliers. It might store supplier price and expected delivery date.

Thus, material master gives SAP information about material, whereas purchasing information record adds purchasing information about certain suppliers to it. Both help buyers create accurate purchase orders.

6. What is the difference between a purchase requisition and a purchase order?

A purchase requisition (PR) is an internal request to buy something. It starts the purchasing process. A purchase order (PO) comes later. It is the formal order sent to the supplier.

For example, a team needs ten chairs, so they raise a PR. Once the request is approved, the buyer creates a PO and sends it to the supplier. Simple enough.

7. What are the different types of purchase orders in MM?

MM supports different types of purchase orders based on how the goods are bought or handled.

Common ones include standard purchase orders, subcontracting POs, consignment POs, and stock transport orders. A standard PO is used when a company buys goods directly from a supplier.

A subcontracting PO is a little different. Here, the supplier processes or makes the goods using parts provided by the company.

8. What happens during goods receipt in MM?

Goods receipt is recorded when materials are received from a supplier. It tells SAP that the ordered goods have been received.

Users can post a goods receipt through MIGO. For a standard purchase order receipt, movement type 101 is commonly used.

After the receipt is posted, SAP generates a material document and updates the stock if needed. It may also create an accounting document to record the value of the received stock.

9. What is invoice verification in MM?

Invoice verification is the step where SAP checks whether a supplier's invoice matches the purchase details.

SAP can match the purchase order, goods receipt, and invoice to check their details. This is known as three-way matching. If the details match, the invoice can be posted.

10. What is the difference between unrestricted-use, quality inspection, and blocked stock?

SAP uses different stock types to show whether materials are ready for use.

Unrestricted-use stock can be used normally. Quality inspection stock is held while the quality team checks the material. Blocked stock cannot be used for normal business activities.

11. How do you configure automatic account determination in MM?

MM uses automatic account determination to choose the right G/L account for stock postings. The setup uses valuation classes, transaction keys, and account rules.The system makes use of valuation classes, transaction codes, and account determination rules. In SAP, the tool OBYC is used for setting up these.

For example, at the time of goods receipt, SAP considers the account determination rules and automatically posts the value of materials in the inventory account.

12. What is the connection between MM, FI, SD, and PP?

MM works in tandem with FI, SD, and PP for exchange of material and purchasing information on a day-to-day basis.

FI records stock values and vendor invoices. SD uses material and stock data for sales and delivery. PP uses material information for production planning.

13. What are the key changes in MM in S/4HANA?

S/4HANA brings changes to MM, including a new data model and updated tools.

Business Partner is used to manage vendor data. MATDOC stores material document data for stock movements. Fiori provides role based apps that make common tasks easier to access.

14. How do you troubleshoot a failed goods movement in MM?

Start with the SAP error message. It usually gives a clue about what went wrong. Then check the material, plant, storage location, movement type, and available stock. The posting date and user access should be checked too.

For example, a goods issue can fail when there is not enough stock. Check the stock first. Fix the issue, then try the movement again. Simple as that, but it’s an easy step to miss.

15. What challenges can arise during MM implementation?

MM implementation can run into a few common problems. Data may be wrong or incomplete. Business needs may not be clear. Testing may be rushed. Issues in other SAP modules can cause trouble too.

Take vendor data as an example. If the vendor details are wrong, a purchase order may fail later. Cleaning the data early helps. So does testing real business tasks before go-live. User training also gives the team time to spot and fix problems.

MM Interview Questions for Scenario-Based Interviews

These MM interview questions are based on real work situations. 

16. What would you do if a purchase order is not getting approved?

First, I’d check the PO status and see where the approval process has stopped. Then I’d look at the assigned approver, PO value, approval rules, and any error message.

17. How would you handle a stock difference between SAP and physical inventory?

I’d start by comparing the stock shown in SAP with the actual physical count. Then I’d check recent goods receipts, goods issues, and stock transfers.

If the numbers still don’t match, I’d ask for another physical count to rule out a counting mistake. Once the difference is confirmed, I’d follow the approved process and post the stock adjustment. After that, I’d check the stock again.

18. What would you do if an invoice amount does not match the purchase order?

First, I’d compare the PO price, goods receipt quantity, invoice amount, and tax details. I’d also check the allowed limits and see if the invoice has been blocked.

19. How would you handle a supplier who repeatedly delivers materials late?

I’d first check the supplier’s past delivery records and current open orders. Then I’d speak with the supplier to understand what is causing the delays.

After that, I’d work with the buying team to adjust the delivery plan if needed. If the same problem keeps happening, I’d check other approved suppliers and see how the delays are affecting the business. Sometimes a different supplier may be the better option.

20. What would you do if a goods receipt was posted to the wrong storage location?

First, I’d check the material document and confirm where the stock was posted. If the goods receipt itself is correct and only the storage location is wrong, an approved stock transfer may solve the issue.

In some cases, the receipt may need to be reversed and posted again to the correct location. Once it’s fixed, I’d check the stock balance in SAP and make sure it matches the actual records.
