For example, to specify a link to apply to deep copying or deep deleting of the revenues associated with an opportunity, add the user property Deep Copy/Delete Link: Revenue with value Opportunity/Revenue to the Opportunity business component. Opportunity is the parent and Revenue is the child business component of the Opportunity/Revenue link.
You can inactivate or modify the values for this user property. You can also create new instances of this user property.
CAUTION: Before you inactivate any predefined instances of this user property in a production environment, do thorough planning and testing to confirm that the child records that are to be no longer copied or deleted are those you intended, and that records of other business components related to those child records are not adversely affected.
