Master data in MM module contains all the basic information need to manage a material. These data records are stored centrally and are used and processed on a cross-application basis. Material Management of SAP maintains the records of various activities and processes material procurement, material modification and production, such as purchasing materials, storing and maintaining them. Creating masters is the basis to start any implementation, which reduces repetitive work and minimizes the chances of errors.
The following are the list of master records in SAP
- Material Master
- Service Master
- Vendor Master
- Purchasing info record
- Source List
- Quota Arrangements.
Material Master
The Material master contains all data required to define and manage material.
It integrate with various departments of the company (eg: Sales and Distribution, Purchasing, Accounting, Production etc)
The material master is used as a source of data for processing procurement cycle.
Material master contains the information of material type, price control, industry sector, size, and dimension etc. Information is stored based on the views selected by the user departments.
Below are the list of views available in Material Master Record
1. Basic data 1 & 2
2. Purchasing
3. General plant data storage 1 & 2
4. Warehouse Management 1 & 2
5. MRP (Material required planning) 1,2,3,4
6. Accounting 1 & 2
7. Costing 1 & 2
8. Quality Management
9. Plant Stock
10. Storage Location Stock
11. Classification

Following are the list of mandatory things to create Material Master
- Material Types
- Industry Sector
Material types:
It is a key that assigns the material to a material type such as Raw materials, trading goods. This allows you to manage different materials in a uniform manner in accordance with your company's requirements.
The Material type represents the group of materials that have same basic attributes.
Use: When creating a material master record, the material type determines
- Purpose of the material should be the same material type
- Whether the material number is assigned internally or externally
- From which number range interval the material number comes
- Which screens are displayed
- The order in which screens are displayed
- Which department-specific data is displayed for the user to enter
- The material procurement process should be same for all the materials in the material type.
- Price control is done in material type configuration. It can be either
- Standard price (S)
- Moving average price (V)
Customizing Path: SPRO (T code) ---> IMG ----> Logistics General---> Material Master ---> Basic Settings---> Material Type ---> Define Attributes
