Abort a schedule or summary task
Caution: Once a schedule or summary task has been set to Abort, the status cannot be changed or reversed.
The schedule coordinator can abort a task or a collection of tasks within a schedule. If tasks are aborted, the schedule itself is not aborted and any tasks not aborted execute as scheduled. If there is a workflow or remote workflow in execution for the aborted schedule task, Teamcenter aborts the workflow or remote workflow. If the workflow has completed or is not executing, Teamcenter does not abort it.
If the schedule coordinator aborts a summary task, all of its In Progress and Not Started subtasks are aborted too. If a subtask is another summary task, all of its subtasks are aborted as well.
Procedure
- In Schedule Manager, select the task and choose Schedule→Abort.
- In the Abort dialog box, select the Aborted status from the list and click Yes.
Teamcenter aborts the task and associated subtasks and updates the scheduled task in the workflow or remote workflow. It sends an email to all coordinators and assigned users of the tasks. However, the tasks remain in the database in case the data is needed in the future.
Note: Aborted tasks and schedules with aborted tasks cannot be deleted.
