I have a business group (most of them new to JIRA) that is tracking their work with tasks and subtasks. They want to run a query that will show each task with its related subtasks grouped underneath. They want to be able to export the results to Excel (which I expect can be done via csv). We're using a local (server) installation of JIRA Software 7.1, and this group is currently using a "Business" project, though we're willing to change the project type (and issue types, for that matter) if that would let us do this.
I've been digging through the documentation, Answers and also Stack Overflow, but can't find any way to do this (at least not without adding plug-ins). I've been thinking that maybe the best way to go is a calculated custom field that would return the same value for each parent + all its children, then create a filter and order the results by (first) that custom field and then (second) by issue type within that. But maybe there's some easier way I'm overlooking?
Any guidance appreciated... thanks!
