Searching for issues using Advanced Roadmaps details
Does issuekey in parentIssuesOf("EX-000") is supported in Jira cloud?
This is from the link:
- For parent issues of an issue in a specific hierarchy level in Advanced Roadmaps, type issuekey in parentIssuesOf("EX-000").
- For instance, you have this hierarchy:
- INIT-001 (at initiative hierarchy level)
- EPIC-001 (at epic hierarchy level)
- EPIC-002
- STORY-001 (at story hierarchy level)
- STORY-002
- To get the parent issues of STORY-001, type issuekey in parentIssuesOf("STORY-001"). All parent issues above STORY-001 will be returned, and not just the immediate parent issue at the epic hierarchy level. This means EPIC-002 and INIT-001 will be returned.
- If needed, you can skip returning issues of the hierarchy levels you don't need. For instance, if you want to return just the initiative-level issues, type issuekey in parentIssuesOf("STORY-001") AND issueType != Epic.
