How to upload labels from Bartender to SAPScript

Hello all,

I am designing some labels using "BarTender" software.

I have the following doubts.

1. I need to print the FI doc.no &BKPF-BELNR& field as a barcode, Where can I assign this program symbol (&BKPF-BELNR&) name to the barcode?

2. When I save the label using Bartender it is getting saved as " .btw " file. How to upload this file into SAPSCRIPT?

Can anyone please give some inputs on the above two things.

Useful answers will be rewarded.

Best Regards,

Nag
