Hello,

how it is possible to trigger a barcode scanner by a dynpro button. I want to scan a barcode and then insert the number into a dynpro field.

Any function modules or programs?

Best Regards Sebastian

Hi,

First off, sounds like a really interesting task.

Second, there are a lot of barcode devices out there. So to every one of them, a different solution could work.

That being said, I would Google/contact the supplier for some executable that triggers the reader and (assuming your web Dynpro is running on MS Windows frontend) then use this to fire it.

Hello,

thank u for your answer. But i dont use web DynPro .

The SAP CCS transaction WB2R_AB_DOCS can trigger the barcode scanner via billing document type . I try to reproduce this in a custom transaction.

I'm quite confused by this question... Can you explain what are you trying to achieve exactly?

To my knowledge, barcode scanner is an input device, just like keyboard. We don't "trigger keyboard", do we? It's the other way around: you enter information using keyboard / scanner, hit the button and SAP does something. With this in mind, the concept of "triggering scanner" just seems rather odd to me.

We don't have the transaction WB2R_AB_DOCS in our system.
