Abort a task workflow and its associated task

Caution: Once a task workflow has been set to Abort, the status cannot be changed or reversed.

The schedule coordinator or an authorized schedule participant can abort a workflow, which aborts its root task. This cancels all workflow processes currently executing. If a schedule task is associated to the root task of the workflow, the schedule task is also aborted, unless the participant who aborted the workflow does not have permission to abort schedule tasks.

Note: To ensure the workflow task abort is reflected in the schedule task state, the user performing the abort operation must either be the schedule coordinator (not just a participant member), or the SM_ALLOW_USER_ABORT preference value must be set to true. If these conditions are not met, an email notification is sent to the schedule owner, indicating that the schedule task is not aborted even though the workflow task is.

Procedure

  1. In My Worklist, select the task and choose Actions→Abort.
  2. (Optional) Type any comments you want to appear in the audit file.
  3. Click OK.

Results

If a workflow is aborted, the schedule task in the workflow is marked as aborted. If the system is configured to support this task in workflow, the system sends an e-mail to the assigned users. The task remains in the database in case the data is needed in the future.
