An item is returned back and the barcode is missing from it. What should I do?

First you need to find out what the barcode number was. If you know what production returned the item, then go to the checkin by production. Filter the list to show the items that are not returned. Look at the description of the item to find the barcode. Checkin the barcoded, then go to the inventory screen and select this barcoded item. From the Add Item menu option, select Reassign Barcode, and assign it a new barcoded item.
