Email notification for category change
Is there a email notification that is sent up if a existing ticket gets their category changed to a category that sends notifications on new tickets?
Nope you need to setup a ticket rule to send the email, use the TICKET_CHANGE table for the SQL and identify what text you want to pick out to trigger the rule
For example "Changed Ticket Category" so set the SQL if the value of the HD_TICKET_CHANGE.DESCRIPTION BEGINS WITH 'Changed Ticket Category'
Then send the email from within the ticket rule, so you may need to select the email address of whoever will receive the email in the SELECT statement, hint, hide it in a hidden unused Custom field as a default value ;o)
I hope that helps
