Spool to PDF - Problems with downloading PDF file when converting with job

Question

Hi all!
I've got a problem. I've got a program that writes a smartform into the spool. After that, I am using the function modules RSTS_GET_ATTRIBUTES and CONVERT_OTFSPOOLJOB_2_PDF to convert it into PDF. I retrieve a internal table with the binary content for the PDF file. Now i can download the file to the desktop by using the method cl_gui_frontend_services=>gui_download.
But there is a problem: when the spool excesses 99 pages, the function module CONVERT_OTFSPOOLJOB_2_PDF asks the user via popup if the PDF should be created in background. If the user commits, the internal tables that should contain the binary PDF data is emtpy. A background job writes the binary data into the spool. The user has got an empty file that will be generated by cl_gui_frontend_services=>gui_download.
So, is it possible to suppress the popup to create the PDF allways online? Or how can I write the PDF file if there will be create any spool id in background? You'll find my current code below.

Creating a PDF file with over 99 pages through SAP seems rather unreasonable to me. What are you printing - Encyclopedia Britannica? For cripes sake... Have you thought about creating more than one spool request or using something completely different? Why do you have to do this through spool? You can get Smartform output directly into PDF, there are a lot of example out there.
The only solution that comes to mind is rather brutal - create a copy of the function module and get rid of the popup. Although it just might time out after that...
