Using Work Queue to End Activity on Serially tracked Operation

Has anyone ever successfully used the End Activity function in the Workqueue, where the operation is Serially tracked. I maybe trying to ask too much of work queue here, but in our business we make mutiples of a part in a given job, all of which will be auto received into inventory upon completion of the final operation. These parts are also serially tracked.

Just playing around with the work queue tring to complete a job using it, and I never receive a prompt requesting a serial number, just an error saying that the serial number is missing??

Hi
just saw your question, Do you find any solution for serial tracked parts?
Thanks in advace.
