Can't group by a field in Structure

Problem

I want to group by a Jira field in my structure, but I don’t see this field on the Group By Field list.

Solution

The standard grouper - a Group generator or a Group transformation - cannot work with some types of fields due to their nature. Text fields, date fields, duration fields, and fields of some third-party apps are not supported.
However, it is possible to group by them using the Formula Group generator: https://help.tempo.io/structure/latest/group-by-formula-generator
