To enable the R/3 System to output values as bar codes, proceed as follows:

1. Acquire a registered font for your barcode and install it.
2. Write your own conversion program (ABAP function module) that adjusts the values. The interface must correspond with the function module C128_DUMMY_CONVERSION_METHOD.
3. Use the function module C128_DUMMY_CONVERSION_METHOD as the method for the corresponding symbol in the template (expansion mode M) or in the symbol definition.
4. Format the symbol in the template with the corresponding font.
