I've requirement in which i've created sequential workflow. In workflow, the taks is assigned to the sharepoint groups(i.e.Checker) sucessfully. the users of the checker group is getting an email about the task.
Now suppose one of user from group(i.e.Checker) is open the task form and update the task. so at this level, task is sucessfully completed.
Now there is another user belongs to same group(i.e.Checker) also going to open form(i.e.task form) from an email. but here i want to prevent those user to update the task. Because task is already complete.
So how can i prevent users belongs to same group from updating task which is already completed ?
Please provide solution!!!
