I have a validation rule that prevents re-opening case after a certain period has passed. But we'd like a Connection User from a partner org to be exempt from this rule. The problem is, how can refer to the Connection User or the partner org in my validation rule? The Connection User isn't a real user per se, has no role, nor profile.
Are my only options to mark these cases with a trigger on insert time and use that to refer whether this is an external or internal case?
