QR code version control in SAP Adobe form layout

Hi All,

I am trying to use "QR Code" barcode in my adobe form layout which is binded to a global variable getting data in initialization.

However, the QR code image would get generated only when it has data upto 26 characters(if the data is alpha numeric in lowercase) or 38 characters(if the data is alpha numeric in uppercase).

I beleive the QR code supported in my layout is "Version" 2 and "ECC Level" M. Irrespective of changing values in "Data Length" property under Field tab of the QR code, the image would not get generated beyond 26/38 characters. There is no clue in the generated XML source too.

How can I include more number of characters and still get the QR image?

Thanks,

Sathya.
