About attribute value hierarchy
Some system required attributes can be applied to a group or area object so that the value of the attribute is inherited by the member objects.
Note
Most attribute values are NOT inheritable from the parent group or area.
When an attribute value is set directly on an object, that attribute value takes precedence over any inherited group values. However, when the object inherits a group value, it can be difficult to determine where the value was set because groups can contain other groups and areas. Tracing the attribute hierarchy can be a useful troubleshooting tool.
