Why the material master matters in SAP MM
Want to build material masters on a live S/4HANA system? The SAP MM course at Cokonet Academy covers master data, purchasing, inventory and invoice verification hands-on.
Quick answer: Every logistics transaction copies data from the material master: the unit of measure into a purchase order, the valuation class into an accounting entry, the MRP type into planning. Clean material data keeps the SAP MM module running smoothly.
In practice, most support tickets in a new SAP MM project trace back to master data: a missing purchasing view, a wrong price control, a material not extended to a plant. Consultants who understand the views fix these in minutes.
Material master views and their organisational levels
Quick answer: Views group fields by department. Some are maintained once for the whole client, others per plant, storage location, sales area or valuation area. You must extend a material to each organisational level where it is used.
| View | Level | Key fields |
|---|
| Basic Data 1 and 2 | Client | Description, base unit of measure, material group, gross and net weight, division |
| Classification | Client | Class and characteristics, used for batches and variants |
| Sales: Sales Org 1 and 2, Sales General/Plant | Sales organisation, distribution channel, plant | Delivering plant, tax classification, item category group, loading group |
| Purchasing | Plant | Purchasing group, order unit, purchasing value key, goods receipt processing time |
| MRP 1 to 4 | Plant | MRP type, MRP controller, lot size, safety stock, procurement type, planned delivery time |
| Plant Data / Storage 1 and 2 | Plant and storage location | Storage conditions, shelf life, batch management |
| Quality Management | Plant | Inspection setup, QM control key |
| Accounting 1 and 2 | Valuation area | Valuation class, price control (S or V), moving average or standard price |
| Costing 1 and 2 | Plant | Costing lot size, origin group, with quantity structure |
Material types in SAP
Quick answer: The material type controls which views are allowed, whether quantities and values are updated, the number range and the default price control. Common standard types are ROH, HALB, FERT, HAWA, DIEN, NLAG, VERP and ERSA.
- ROH: raw materials, bought and used in production
- HALB: semi-finished goods, produced and consumed internally
- FERT: finished goods, produced and sold
- HAWA: trading goods, bought and sold without processing
- DIEN: services, with no stock
- NLAG: non-stock materials, such as consumables expensed on receipt
- VERP: packaging materials
- ERSA: spare parts
Companies often copy these into their own Z types. Material types are configured in OMS2.
The fields that cause the most errors
Quick answer: Base unit of measure, valuation class, price control and the purchasing group cause most problems. Get them right at creation, because some cannot be changed once stock or documents exist.
- Base unit of measure: every quantity is stored in it. Changing it after transactions needs a special process.
- Valuation class: links the material to G/L accounts through account determination (OBYC). A wrong class posts stock to the wrong account.
- Price control: S (standard price) or V (moving average price). Finished goods usually use S; bought materials often use V.
- Purchasing group and order unit: drive who buys and in which unit.
- MRP type: PD for MRP, VB for reorder point, ND for no planning.
Our guide to movement types in SAP MM shows how these fields drive each goods movement.
Material master T-codes
Quick answer: MM01 create, MM02 change, MM03 display, MM06 flag for deletion, MM60 materials list, MMBE stock overview, MM17 mass maintenance and MM50 for materials to be extended.
In S/4HANA many users work through Fiori apps such as Manage Product Master Data, but the classic T-codes still run and are expected in interviews. Our SAP MM T-codes list covers the rest of the module.
Material master in S/4HANA: what changed
Quick answer: The material number can be up to 40 characters, the product master Fiori apps sit alongside MM01, the material ledger is mandatory for inventory valuation, and customers and vendors moved to Business Partner, while the material master itself stays largely the same.
For learners, that means classic material master knowledge still applies. What is new is the simplified data model and the Fiori screens that consultants are expected to navigate. You can see every SAP programme we offer on the all courses page, or start at the Cokonet Academy homepage.

Material master questions asked in SAP MM interviews
Quick answer: Expect questions on views and organisational levels, material types, price control, valuation class and how to extend a material to a new plant. Interviewers often ask you to explain an error caused by missing views.
- Which views are maintained at plant level?
- What is the difference between standard and moving average price?
- How does the valuation class link to G/L accounts?
- How do you extend an existing material to another plant or storage location?
- Why might a purchase order fail for a new material?
