In short,

GUI_UPLOAD - uploads a file from your desktop or laptop into an ABAP internal table within your program - you can then use that data for your program's needs

GUI_DOWNLOAD - downloads an internal table from your ABAP program into a file on your desktop or laptop

hi

good

Please note that function download/upload come with user interaction

(popup to ask for a filename). The new functions or methods don't do

that. You first have to execute another method from

cl_gui_frontend_services to call for this.

thanks
