Hi. I realise this is probably simple, but can’t figure it out.
I am trying to get the Hours Spent for Jira issues with an Issue-Type of ‘Project’ plus the Hours Spent on sub-tasks with a parent who’s Issue-Type is ‘Project’
For your report, you might want to use measure “Hours spent with sub-tasks” and filter data by Issue Type of parent issue, in your case Project. Then measure will return logged hours on Project issues as well as on Sub-tasks under project issues.
