In the Registry Objects area, select two objects and click Relate.
In the Create Relationship area, select the source object if it is not already selected.
The other object becomes the target object.
If a valid reference exists for the source and target objects, the Reference option is selected by default, and the valid reference attribute appears. If no valid reference exists for the source and target objects, the Reference radio button is grayed out.
Click Save to save the Reference.
