Default is checked.
When this option is checked, this indicates that when an instance of the child object (e.g. EMPLOYEES) is selected, all the commands associated with the parent object (e.g. SECTIONS), should also be enabled and made available for use. If this option is unchecked the parent's commands are disabled.
This option only applies when the business object is not selectable from the navigation pane. This option is disabled if the 'Allow Selection from navigation Pane' option is checked.
This property is in the Business Object Relationships tab.
