Hello, 

As FS do not save history of a ticket I would say a tag or not. Then use view or a report to show how many. 

Hi.

There may be several ways to achieve what you are looking for, depending on your needs.

We have Level 1 (L1) groups and Level 2 groups (L2).

When a ticket is Escalated, we set up a workflow to transfer the ticket to the corresponding L2 group, and ticks / sets an internal custom variable called Escalated, and we perform several statistics with that.

Hope this helps.

Sincerely,

Hi, 

To clarify my suggestion, is to use a automation that trigger on change group from “initiating group” to any 

Action Set tag {{ticket.group.name}} or if you wish to use tag called Escalated. 

Then a report on easier the tag Escalated or each groups Tag. In case you have Pro/ENT
