Postwork scripts are commonly used to perform tasks after task is completed. This script may be useful for updating databases or generating documents by the user entered data.

Because task is already completed, some operations (example; trying to set an action on a current work item) are invalid at this stage and error is thrown.

Postwork script defined area is reached from a related task. When you click on the "Postwork script" button on the task, postwork script page will open.
