Filter down Epics with JQL

By default, the roadmap timeline will display all Epic Issue on the project that has been enabled. You can further filter your Project's Epics displayed on the roadmap by providing a valid JQL to extend the default filter term: project = [project] AND issuetype = [Epic issue type] AND [your expression]

• If the field is empty, the following expression will be applied and the roadmap will display all Epic Issue on the project that has been enabled: project = [project] AND issuetype = [Epic issue type] ORDER BY createdDate DESC
• The provided expression should not include the ORDER BY clause.
• The provided expression should not include other project(s). If provided, the roadmap won't display any Epic Issue due to the AND operator.

For example, you can filter your Epics based on the reporter. In this case:

• provide the following expression: reporter = "douglas.arnold"
• the concatenated JQL for the roadmap will be: project = [project] AND issuetype = [Epic issue type] AND reporter = "douglas.arnold" ORDER BY createdDate DESC
