A serial number was incorrectly allocated against a WO at completion, can this be corrected?

We have an item that is serial controlled, at receipt, and a serial number for the item was allocated against a Work Order when the WO was completed.  It has since come to light that the serial number that was allocated is incorrect.  Is there a way to correct this?  We have tried to do a misc issue out of Inventory for the item but cannot select the serial number as it does not show in the form.

Any help would be much appreciated!

Thanks,

Amanda.
