Lock Opportunity Contact Role record

Question

Since the OpportunityContactRole object is not a first class object you cannot create a trigger on the object, nor add fields or create a validation rule. Is it possible to prevent the deletion of an opportunity contact role record that is inserted during lead conversion and marked as primary using a trigger? I need to identify an opportunity contact role record that is created during lead conversion and marked as primary and prevent that record from being deleted and lock it down.

Answer 1

I think the only workaround is to change your business process to use a custom lookup field on Opportunity to fulfill your primary contact functionality. When users modify the lookup field, an opp trigger can create / modify the appropriate opportunity contact role record.

Of course there's still no good way to deal with the situation where a user deletes the opp contact role, but at least the lookup field value will remain, plus you can use field history tracking on it.
