We recently implemented a process for service requests that assign tasks to each technician involved in the process of user administration in order to maintain just one ticket.  I have it set that each technician is notified via email when they are assigned their tasks - they complete it and then close the task.  I have also set it so that all tasks must be closed before the request can be closed.  I need a means of knowing when all tasks are completed and closed that preferably does not involve opening each ticket daily and seeing whether all tasks are done.

Is there a report I can run or a rule to set to notify me when all tasks are complete?

Thank you.
