Is this is entire code ? bcos I do not understand the code. You are trying to save a file and then trying to download something to a file . When you already saved the file using the
cl_gui_frontend_services=>file_save_dialog
why are yoiu trying to download again ?
In anycase you should get a prompt that asks you to something like "Do you want to overwrite ?" after you uncommented the CONFIRM_OVERWRITE = 'X' line .
