All the information your company needs to manage a material is stored in a data record in the material master, sorted by various different criteria.
You can enter and change most of the data in a material master record yourself. However, some information can only be updated by the system. For example, the system updates the administrative data when you process a material master record, and stock balances when goods receipts or goods issues are posted.
The data in a material master record can be divided into two categories:
Data of a purely descriptive nature
This is data with an information content such as name, size, or dimension.
Data that the system uses to perform a control function
This is data such as MRP type and price control.
Since different departments in a company work with the same material, but each department uses different information on the material, the data in a material master record is subdivided by user department. For more information, see User Departments .
