Why is Related List data not appearing on the Record Detail view of a parent form?

If you have a Related List on a Directories form and it is not displaying the expected data on the Record Detail view, you may need to alter the menu settings of the main form. In order for Related List data to appear on a Record Detail view of a parent Directory form, the parent Directory menu item must have the Enable Default Results parameter set to Yes.

This parameter setting is not required when a Related List is included on a List Display view.
