Visibility Rules for the Drilldown Object Type
If the drilldown view is a detail view that does not have visibility specified and the drilldown object does not have visibility specified, then visibility on the drilldown view’s screen applies in the following order:
All
Organization
Manager
Sales Rep
This scenario assumes that the business component is configured for visibility.
Note: You can only specify visibility on an ID-based drilldown object.
