For example, if tasks are grouped by the Critical group, the GroupMaintainHierarchy True command shows the summary tasks in the Critical: No and Critical: Yes groups. The GroupMaintainHierarchy False command hides summary tasks in the groups. If no group is applied to the view, GroupMaintainHierarchy has no effect.
