File server-Help!

Question

Hello Everyone,
My program not working when sceduled to run in background, but works fine when run in foreground. Think i need to change some funcution modules as the ones i used are, think, referencing for foreground processing. Can anyone point to some function modules which does the job for me.
I am picking up the files from file server.

Answer 1

The methods of the class
cl_gui_frontend_services
cannot be used in background since they refer to the presentation server. You have to upload the files to the application server to run the program in the background. You can use transaction CG3Z or the function module
ARCHIVFILE_CLIENT_TO_SERVER
to upload the files.
