You can apply various task management actions to the tasks in the Task List Management Tasks panel. To do so, a task must have a status of Active or Suspended. You cannot apply task list management actions to tasks with a status of Canceled, Completed, Error, or Expired.

From the point of view of the Task Engine, tasks with a status of Canceled, Completed, Error, or Expired are all considered as terminated tasks upon which no further work is to be allowed. If you want to restart a task in any of these states, you must use webMethods Monitor to resubmit the task; for more information, see webMethods Monitor User’s Guide.
