Clicking on “Links Hierarchy” will navigate to the below screen. Select a Project from the drop down.
And specify the Issue Link on which your Hierarchy is based.
Either click on “Load Hierarchy” button to load all the epics of the project or select a single version and load its details. The report will show rolled up estimates (time/story points progress) at top level for all the issues in the epic.
Edit Issue Summary, Status, Assignees, Estimates or Story points right on the Hierarchy report.
