save pdf in background mode

Hello gurus!

I am searching all over internet and i cannot find a solution for saving a pdf document in background mode. I have develop a report and i use CONVERT_OTF function to convert data to pdf, and then the GUI_DOWNLOAD function to download the file.

It works fine in online mode.

Can anyone tell me spesific what to do in order to make this damned report run in background??

Thanks in advance!
