Re: Serial number

In 1 firm I was with, with or without a bar code, the serial number  was key. 
We had a program written that when an RM or an SA transaction was being  
processed, the reference field had to be populated with at least the letters 
n/a  
if the rare case of no serial number was used. Along with that, we had a query 
 to match the reference & item number fields of the RM with a corresponding  
SA fields daily to insure that an inventory item which required a serial 
number  for shipment had been manufactured and serialized. It was a quick check 
every  day.
 
Any customer inquiry by serial number was available through a query run  
through the history file in a serial number search of the reference.
