Hello,
You can use the Class CL_GUI_FRONTEND_SERVICES in which you'll have the Methods GUI_UPLOAD and GUI_DOWNLOAD using which you can download the File from the Application Server.
After that, you can call the FM "CONVERT_OTF" using which you can generate the PDF File. You can open the same PDF file using the Method CL_GUI_FRONTEND_SERVICES=>EXECUTE to which we'll have to pass the Name of the PDF File as parameter.
Thanks and Regards,
