1) Add an automated email alert for P1 tickets. This needs to fire if a ticket is created as a P1 or if priority is changed to P1. Alert should only fire one time. I created a Business Rule that fires on create or edit. Problem is that it fires every time the ticket is updated.
2) We have a Status called On Hold - Customer Working. I would like to have this status changed to In Progress if the customer sends in a response. This would only fire if the current status is On Hold - Customer Working.
