In Rally, milestones are scoped to specific projects. By default, viewing milestones at a parent project level may not display or allow for the download of milestones associated with child projects unless they are explicitly workspace-scoped.
Release : SAAS
Standard Milestone and Timebox pages in Rally are designed to respect the current project scope and do not provide a "down-scope" (include children) option for the default list export.
Work items and milestones must share the same project.
If you move a work item to a new project after associating it with a milestone, the work item will keep existing milestone(s) only if they exist in the new project.
When you reparent projects or related projects associated with a milestone, the milestone is unaffected and the work items continue to be associated with the milestone.
Child projects automatically inherit all milestones of the parent project.
Your permissions level determines which milestones you can see. Subscription administrators can see all milestones, regardless of the project. However, the page only displays milestones defined in the current
workspace. Workspace and project administrators are limited to viewing milestones associated with projects that they have permission to see.
To view and export a complete, cascaded list of milestones across a project hierarchy, use a Custom List widget:
