When you create a new hierarchy, it becomes the active hierarchy and any changes to nodes, account assignments, and service assignments only affect that hierarchy. If you are an administrative user or user assigned to the top node, you can change which hierarchy is active. (If you're not the administrative user, contact your system administrator for help.)
To make a hierarchy active:
Did you know? You can rename a hierarchy. To do this, click the Setup tab, in the Hierarchies box, click the Set Hierarchy link. Select the hierarchy you want by clicking its circle, click Edit Hierarchy Properties, edit the hierarchy name, then click Ok.
Any hierarchy you make active stays active until you log out. The next time you log in, the master hierarchy is automatically set as the active hierarchy. If you want to use a different hierarchy, you need to set that hierarchy as active.
