Creating a PDF-file trough Forms 11gR2

Hi,I have migrated my Forms and Reports from 6i to Forms 11 G R2. The weblogic server is running on a windows 7 virtual maschine.
In Forms 6i there is a button to start creating a PDF-file saving immediatly to a given directory, without opening the report first.
This is the call in 6i
-- Ablage des Protokolls gleich als PDF-Dokument
       Add_Parameter (pl_id, 'PARAMFORM',  text_parameter, 'NO');
         Add_Parameter (pl_id, 'DESNAME',  text_parameter, vFilename);
         Add_Parameter (pl_id, 'P_UnfallID',  text_parameter, to_char(:KT_unfall_muc.id));
         --
         SubCall.Call_Reports (vReport, SYNCHRONOUS, pl_id, 'sallg_reports_man');
