I hope someone can improve this answer or provide a better one. If there are many products at a location and many stock moves then it becomes impossible to eyeball which serial numbers are left at that location.

Go to Settings/Configuration/Warehouse........ Under the traceability heading put a check on the Track serial number on products......... I havent seen how it works but i know that once you check it you will be required to give a serial number to each product and will be able trace it via its serial number...
