    Hi Amol,

    Check the note 1293379 - EH&S WWI: Supporting bar codes

    WWI itself does not have any bar code functions.

    You require an additional component from a third manufacturer to be able to include bar codes in WWI reports.

    There are two options:

    • Use the WWI bar code interface

    • Use bar code fonts

    Contact your EH&S consultant for more information about the method suitable for you and the corresponding sources.

    • Using the WWI bar code interface requires a program library (WwiBarcode.DLL) of a third manufacturer.

    WwiBarcode.DLL generates a graphic that is inserted into the WWI report from WWI.

    Symbol parameter "B:" is used for the control

    for example, <02EHS_MATNAM[B:CODE128,...]>

    The advantage of using the bar code interface is that no fonts have to be installed on the front end. Furthermore, more bar codes, 2D bar codes amongst others, can be supported.

    • Follow the manufacturer's instructions to use the bar code fonts.

    If the bar code font requires additional prefixes and postfixes, check sums or codes, these must be added using the corresponding symbol processing method. For more information about this, go to the IMG and the SAP Library, for example under:

    Make sure that the complete symbol is formatted with the bar code font on the report template.

    Make sure that you have the correct installation with regard to the licensing of the fonts.

    Bar code fonts cannot be loaded on label printers since there can be no licensing there.

    The fonts must be installed on the WWI server and on the front-end PCs.

    The bar code fonts cannot be entered in the WWI.INI section [fonts] since you do not want to change the font here.

    Another posibility is decribed in

    [SAP Help|]

    To enable the SAP system to output values as bar codes, proceed as follows:

    1. Acquire a registered font for your bar code and install it.

    2. Write your own conversion program (ABAP function module) that adjusts the values. The interface must correspond to 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.
