After a new Work Order is created and a Primary Incident Type populated, at least the following records get populated into the new Work Order coming from the Primary Incident: - Work Order Products - Work Order Services - Work Order Service Tasks - Characteristics If a User changes the Primary Incident Type lookup on the Work Order form, non of the mentioned sub-records gets removed or replaced with those of the new Primary Incident Type. Leading to i.e. Service Tasks which are usually thought to be related to the first Incident Type but now get related to the second new Incident Type. That creates some funny constellations. => If a User replaces the value of the Primary Incident Type field, a warning should appear as if a User deleted a non-primary Incident: "The incident can't be deleted. Delete the associated service tasks and try again.". => After the User has populated a new Primary Incident Type into the field of the Work Order, also the Service Tasks etc. of the new Primary Incident Type should be populated into the Work Order.
