# BOM Management

## Define Contexts

The context views, that will be available for each BOM position can be defined in the Contexts mask (System > Contexts).

New contexts can be defined or existing contexts can be either modified or deleted. New contexts are shown in the BOM structure after refreshing the BOM tab.

The deletion of a context is only possible if this context is not used. A deleted context is moved into the trash basket. To permanently delete the context from the BOM tab, the trashbasked has to be cleared.
