For GS1-128 barcode converter--
1. need to create barcode label using t-code se73 . click on system barcode and create new barcode label which will be use on smartsyles to print barcode.
2. use below parameter for creating barcode label--
supported Bar code symboligies = code 128
barcode alignment = normal
put lenght and weight
code128 mode = N
""" code for SAMRTFORMS""""""
1. in smartforms ->
need to copy below routines in the SAMRTFORMS -> FORM ROUTINES

* Convert the barcode string that is passed in, into a barcode that uses
* the best subsets (B or C) to make the smallest possible barcode. Subset
* C provides the most compact barcode, but will only handle numeric digits,
* subset B will handle Alpha Characters as well.
