Do the Ticket group and Update ticket group attributes refer to the same values?
No, these have different meanings:
- Ticket group: Refers to the name of the group the ticket is currently assigned to.
- Update ticket group: Refers to the group to which a ticket was assigned at the end of an update. For example, if a ticket was reassigned from Tier 1 to Tier 2 in the past, the Tier 2 value will be returned.
