Use case 2
Likewise, as shown in the diagram, the Business Units listed for the root domain may not be relevant for the child domains. In this case, the child domains need to have an override of the list of values.
See Figure: Use case for Overrides of Attribute Values.
Note:
For inherited attributes, you are not permitted to modify attribute names in child domains. However, you can modify/override the list of values and you can enable/disable inheritance for domains that are lower in the hierarchy.
