Setting Dominant/Subordinate Relationships 
Use
The Business Processes substructure contains processes, which appear more than once in different scenarios. You can edit associated items (for example, questions, CI templates ,and transactions) for each process in the substructure in various ways. You can establish a hierarchy between processes in the structure. This allows you to maintain consistency when editing different processes and helps to reduce your workload. The associated items for the dominant process are displayed for all subordinate processes. You can edit all associated items for subordinate processes centrally, from the dominant process. You can, however, enter comments for individual subordinate processes.
Procedure

You can only set dominant/subordinate relationships for processes you have set in scope. For this reason, you should create these relationships after you have set your project scope but before you edit associated items. If you edit associated items for processes and then make these processes subordinate, the associated items for the dominant process are displayed for all the subordinate processes. When you clear the dominant relationship, you can view the original associated items.
