GUI_UPLOAD method of cl_gui_frontend_services to upload data to SAP within ABAP report
The cl_gui_frontend_services=>gui_upload abap method is used to upload a file into SAP. This is supposed to be the recomended way of uploading files into SAP but to be honest it just executes the gui_upload function module so using this should be the same as using the upload 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.
