There are a few checks for the Dispatch'r to work and to figure out the reason for the same.
- Check if the conditions match.
- If true, then click on the Activities inside of the ticket and check if there was a different rule that worked on the ticket.
- If yes, then make sure the Rule that should have worked is placed higher up in the list of Dispatch'r rules under Admin--> Dispatch'r.
Only one Dispatch'r rule would get executed for a ticket. Therefore, the first matching rule would be executed and therefore it is important to place the rarest rule at the top and the most common at the bottom of the list.
If in case you want an action to be performed on all tickets, add the action to all the Dispatch'r rules.
