Device Category Creation 
Use
This function allows you to create device categories in the Utilities Industry (IS-U) component.
Integration
This function is integrated with the application components Logistics (L0) and Materials Management (MM).
The IS-U device category is an extension of the Material master in the Basic Logistics Data (LO-MD) application component. You maintain the material master in the Materials Management (MM) application component.
Features
You have the following options for creating a device category:
You can create the material master in MM first .
When you do this, a material master for IS-U is automatically created in the background.
Subsequently, you must extend this material master in IS-U as a device category with IS-U-specific data.
You can only create the material master as a device category in IS-U.
When you do this, a smaller version of the material master is created automatically in the background for MM. However, this material master does not allow you to use all of the functions of MM.
If you want to use all of the MM functions available, you must extend the material master you created in IS-U later in MM.
Note
If you use MM, we recommend the first option above.
Prerequisites
You have maintained the following in IS-U:
Register groups
Input/output groups
Command groups
Inspection point groups (optional)
Winding groups (only required for transformers)
