You can add entities to a multi-entity hierarchy. Only the global entity administrators have permission to add entities. We recommend that you assign only one administrator to manage the entity hierarchy. Because an administrator of the global entity by default can only access to the entities that are created by themselves.
To add an entity to a multi-entity hierarchy from the Zuora UI:
After you added an entity to the multi-entity hierarchy, the entity is automatically displayed under its parent entity. Note that the newly added entity is not set up in your Zuora environment until you provision it.
