The material master contains data on all the individual materials that a company purchases, sells or produces. The material master record includes information such as the unit of measure and the description of the material.
The material is the smallest unit or customer pack that can be ordered independently that cannot be split into smaller units. Materials are generally ordered for a plant and then sold. However, they are not always sold in the same form as that in which they were purchased.
A material master record contains the data required to manage a material.
This data can be categorized as follows:
Data of a descriptive nature such as size and weight.
Data with a control function such as the material type.
The figure illustrates the built of a material mater record, which consists of many different information.
Reference materials are used to propose data when creating and extending a material master record. Most of the data defined for the reference material is proposed, except for EANs, consumption values and forecast values.
The generic material is always used as the reference material for the variants.
Subsequent changes to reference materials are not copied to the materials created from them.
There are two types of reference materials:
- Reference material on the initial screen.
- Material group reference material.
It is not possible to use both types of reference material at the same time. If a reference material is entered on the initial screen, it has precedence over a material group reference material. If a material master record was created using a reference material, it is possible to extend it using a material group reference material, and vice versa.
The material group reference material is automatically determined from the material group when the new material is created. It is possible to overwrite this material group reference material by specifically entering another material as a reference.
