The context views, that will be available for each BOM position can be defined in the
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.
