Avoid additional character while scanning barcode

Dear fellow abapers

I've created a smartform for printing barcode, New barcode technology CODE 39 is used for that. It is getting printed fine, but on scanning gives an additional charater 'b' at the end, how to avoid this.

we're using SAPWIN device type.

Regards

    Change your barcode to barcode family C128 instaed of C39.

    C39 usually generates a check digit at the last position of the barcode. Converting your barcode to C128 will remove the additional character.

    • Check the OSS note 645158.

      In the C39 family, it says:

      The start and stop character for the Code39 bar code is usually represented

      by an asterix (*) in the text view of the bar code data (also called

      "human-readable text" or "interpretation line").

      I have never tried this.

    Have you used the scanner on other CODE 38 barcodes? Most scanners have some programmability and can add a prefix or a suffix to a scan or include or exclude the check digit.
