In this IMG activity , you can enter the basic materials that are allowed for materials in your system. When you maintain a material master record, any basic material that you specify on the Basic Data screen in the standard R/3 System is checked against the basic materials you enter here.
Note
The basic material specified in the material master does not have a control function.
If the basic material is not listed here, the system responds in one of the following ways (which you can define in Customizing for the Material Master in the activity Define attributes of system messages ):
It is useful to specify the basic materials allowed if you want to refer to them in programs of your own and you need to be certain that, for example, there are no differences in their spelling.
