I am implementing Major Incident on our standard incident process. We support a number of different organisations (about 20) and so when a major incident is created we only want to inform the organisations that are being affected.
I am trying to create an Action that when triggered will send an email to all the IT leads only once for the major incident and all the child incidents that are attached to this to keep them updated of the major incident, but not to send this to the other IT leads that are not being affected. I don't want to use propagate to children as if there is more than one incident for an organisation this would send them duplicate emails which I am trying to avoid. Is there a way with something like a calculation on the User field or something to do this?
