GUI_DOWNLOAD method of cl_gui_frontend_services to download data to SAP within ABAP report
The cl_gui_frontend_services=>gui_download abap method is used to download a file from SAP to your PC. This is supposed to be the latest way of downloading files into SAP but to be honest it just executes the gui_download function module so using this should be the same as using the FM. Having said that I guess SAP could change this in the future and add differnt functionality to the method. Its also good that all functionality is grouped together within the cl_gui_frontend_services class.
