When creating a material, you need to specify the material type.
The Material type is the highest level of categorization of material masters.
Material Types defined in configuration and below is a summary of main areas that material type influence:
Number range of material master and if it is internal (system allocated) or external (user allocate number)
Which fields in material are mandatory / read only / optional
User departments (Views in material)
Purchase Orders allowed
Valid valuation classes
Quantity and Value update (does it update stock qty and value)
The main configuration of material type is in transaction OMS2
IMG: Logistics > Material Master > Basic Settings > Material Type > Define Attributes (OMS2)
Some settings can be done per plant
This information resides in:
T134 - Material Type
T134T - Material Type: Text
T134M - Material Type: Valuation area data
For number range configuration, the transaction is:
IMG: Logistics > Material Master > Basic Settings > Material Type > Define Number range (MMNR)
First create a Group
Then link the material type to it
This is the main settings of material type. In later articles, we will address other configuration that can be be done per material type.
