Barcode problem: scanner reading extra character at the end

[Former Member]

Folks,

We used barcode format - code39 or cometimes called code 3 of 9 - to print barcodes on documents using a smartform. When we scanned the document, the scanner reads an additional character at the end of the string.

Example: When trying to print barcode 000013000005, the canner reads 000013000005A - As wierd as it is, the last character is not always the same - I have seen A, N, M letters appended so far, when we scanned different barcodes.

Initially, I thought its is like a "escape character", but if thats the case, the last letter read should always be the same, which is not the case here.. (I have seen last letters as A, N and M so far on different barcodes).

Anyone came across this? Please help!

Are you generating the barcodes yourself from SAP? In a SAPscript layout set or ABAP program?

If you are taking data from SAP and printing a CODE39 barcode, you have to add the START and STOP characters. These are a single "*" at each end.

For example, barcode customer number '123456'. You have to actually barcode '123456'.

Norman,

Thanks for the reply. The barcode is on the smartform and is generated from a program. I will try the solution on Monday and award points soon after. Thanks

Norman,

Found the problem finally. When I created the barcode of required size, there is a field called 'Mod 43 Check digit', when I turned that off and put in a space, the extra character stopped coming up. I did not have to put in * before and after the string.

Thanks for the answer anyways, it helped me believe that I am on the right track.
