Useful task attributes: Plans: abort & terminate
Plans have two task-specific attributes, which can interrupt the flow of the process:
|Abort Condition||A truth-valued expression indicating the conditions under which the task should abort. Once this condition is met, the plan’s state is set to discarded. All tasks within the plan that have not been completed are discarded as well.|
|Terminate Condition||A truth-valued expression indicating the conditions under which the task should terminate. Once this condition is met, the plan’s state is set to completed. All tasks within the plan that have not been completed are discarded.|
If the abort condition is used in a plan set in a workflow as in the figure above, because the plan is discarded, the tasks following the plan are discarded as well. Alternatively, if the terminate condition is used, the plan completes, and the workflow can continue.
Note: Abort conditions are only checked when scheduling constraints have been met, whereas termination conditions are checked in advance.
