We use cloud; data Centre 9.4 version of Jira.
Existing hierarchy of issues are as below
Outcome -> Theme & Objective -> Initiative & Key Results -> Epics -> Stories & Tasks -> Sub-Tasks
The parent-child relationship between these hierarchies are identified using either "parentLink" / "EpicLink" field.
In my advanced roadmap plan, I wish to display only issues which are linked all the way up top and remove those who are not part of this chain.
I am trying to use below query
("Parent Link" is not EMPTY OR "Epic Link" is not EMPTY) AND project in ("X", "Y", "Z")
Under the "issues without parent" section in the plan, many issues WITH parent link are getting displayed still.
What could possibly be the reason here? we do have multiple issueTypes in same hierarchy level, could this be a problem, if YES, then how do I resolve it?
