Rank issues
Along with functions like dependencies, ranking issues tells Advanced Roadmaps in which order your work is to be completed. Issues are ranked relative to other issues of the same hierarchy level in your plan. These rankings can’t be surfaced in Jira Software, but they’re essential for using the Auto-scheduler.
Advanced Roadmaps displays an issue’s ranking in the Scope column under # of the highest hierarchy level displayed in your plan. All issues are ranked relative to those with the same hierarchy level, meaning the ranking of an epic won’t impact the ranking of a story.
To see how the child issues are ranked relative to issues in the same hierarchy, limit the hierarchy range visible on your timeline.
To change the ranking of one issue in Advanced Roadmaps, drag and drop an issue to a new row in the Scope section. Its child issues will move with it to the new row on your plan, but their ranking won’t be changed in Jira Software. If you want to re-rank multiple issues at one time, see Edit issues in bulk.
Any changes you make won’t be reflected in your Jira instance until you save them to Jira.
