Go into your barcode attributes and you will see that there is an option for ‘calculate check digit’. On the iSeries, it should be set to *YES. In the MS Windows Editor, it must have a check mark to be enabled.
I created a barcode using the CODE128B barcode. It isn’t being picked up properly when it goes through the scanner.
When using the CODE128B you must specify the check digit option. This is required for this type of barcode.
