Allow certain users to re-assign workflow tasks in SharePoint.
SharePoint by default only allows the assignee to re-assign the task. If you try to re-assign a task that is not assigned to you, you get the following message:
Task update was not accepted. To edit a task associated with a workflow task process, you must be the person to whom the task is currently assigned.
To overwrite this behaviour:
- Open SharePoint Designer
- Open the Workflow you wish to modify.
- On the step where you start the workflow task ‘Start <workflow task name> process on Current Item with…’, right click on the task name.
- Select Properties and look for the attribute TaskProcessOwner.
- Click on the ‘…‘ button to select a group or specific user.
- You may wish to create a SharePoint group specifically for this purpose. All members of this group will have permissions to re-assign tasks that are assigned to other people.
