Reopened lists tasks that were created again from an earlier task. You use the list to see follow-up work after you open a task again.
FeatValue does not put the old task back to open. Create task again creates a new task that points at the previous one. This page lists those new tasks so you can categorise them and open the follow-up.
In the sidebar open Reporting → Reopened. The page title is Reopened Tasks. See Reporting overview.
A task appears here when it was created from another task (the new task stores the old task). Tasks you create from scratch do not appear.
The list sits under Reporting and needs Pro or Enterprise. You see reopened tasks in projects you can access.
Changing the status is not opening the task again. Only Create task again creates the link this list uses.
