WWI Barcode Printing

[Former Member]

Hi Experts,

I am trying to print barcodes via WWI labels. As suggested in the documentation, I have done all the necessary steps that are a prerequisite for barcode labels:

The barcode font code 39(downloaded from a free website -- test purpose only) is installed on both front end as well the WWI server.

A copy of Conversion method C128_DUMMY_CONVERSION_METHOD  is attached to the symbol so as to concatenate '*' at the start and end of the symbol value.

The symbol is included in the template with the code 39 font.

The print preview is working fine but when i try to print this on the printer that value is coming instead of the printer. If I am not wrong there is no printer specific setting involved here so the barcode should have printed as desired.

Can any one please help me identify the problem here?

Thanks,

Navjot

Hi Navjot,

The software which you have downloaded from free website, may limited to the print preview.

Print preview, is just a preview without wwi generation process involved.

You can contact SAP for the licensed software called "genifix",

to implement Genefix, you have to do couple of activities -

1. Implement the BADI - EHSS_WWI_BADI_001

2. couple of Notes to be implemented to control/prevent the errors.

3. To work with genefix, you must install the latest version of wwi (service pack 17 or latest than that).

4. After implementing the above BADI, you will find couple of additional tabs in CG42 related to Barcode.

5. check the BC set release checks, if necesary adapt the SAP NOte - 649918

6. After implementing the genefix, do some macro settings in MS word.

Hi Ravi,

Thanks for your reply on this one.

At this point in time we are looking for a solution to print barcode labels without having any other additional software being involved. I read somewhere that we can do this by installing licensed fonts and then utilizing the custom expansion function module (copy of C128_DUMMY_CONVERSION_METHOD) for barcode based formatting.

It would be really helpful if you can help me understand if this is possible i.e. we can generate barcode from WWI by just using fonts and what needs to be done in the expansion function module for this.

Thanks again,

Hi Navjot,

I am confident enough, that the barcode functionality cannot be dealt without the licensing solution from SAP.

C128_DUMMY_CONVERSION_METHOD, is a general function module to use in any of wwi symbol enhancements. You can deal with this function module to retrieve the data from the database "as same" at report genration. WWi symbol/ value generation from wwi server looks like black box, I don't think it converts the numbers to barcode in wwi generation server with the additional coding in FM.

Had lot of discusions earlier on the same and you can find lot of threads available.

Hi Navjot,

WWI/GLM is supporting barcode fonts.

You have to install the barcode font also on the WWI server.

Are you generating the print preview with GLM (CBGL_MP01). This preview is generated on the WWI server, but a preview in CG42 is a local generation on your pc.

Also a printout is generated on the WWI server. So in that case I would suggest to check the installation of the barcode font on the WWI server.

Hi Navjot Sharma,

You said "A copy of Conversion method C128_DUMMY_CONVERSION_METHOD  is attached to the symbol so as to concatenate '*' at the start and end of the symbol value.can you please tell me  what change exactly you did in copied version C128_DUMMY_CONVERSION_METHOD and how you concatenated start and end symbol.

Hi Kamal Ravirerkula,

By going through the forum, it is learned that there are two options to print the bar code in WWI,

     i.     Using Fonts

     ii.     Using Bar code interface.

Can you explain how to use bar code interface..? Is it mandatory to buy "genifix to use  Bar code interface ?

or

by just implementing the above said BADI, "EHSS_WWI_BADI_001" can we use bar code interface with any bar code library ?

If we implement that BADI or implement "genifix", would we have another expansion mode as "bar code" in report symbol tab along with Expansion modes, "Without", "GPC", "IT", "NM"

Hi Subash Sankar,

when using Barcode fonts you need a conversion method to add the '*' characters around the value.

The font needs to be installed on the WWI Server and on every PC which will display the report.

A more convenient method is to use a barcode library whether through Genifix AddOn for WWI, which can be obtained through SAP Consulting, or by using the new WWI Barcode Interface (which will also need a 3rd party barcode linrary). Please refer to notes:

Thank you Christian Hund for your reply. Now am clear that "Genifix" solution is still available from your reply !. But right now we are interested in using barcode printing using fonts to show demo.

Thanks & Regards

hello Subash,

Did anyone found the code for that dummy function module or if we are not expanding bar code we do not need that code right ?

Hi !

Yes ! You are right ! If you use BARCODE expansion mode, you do not need FM.
