Hi Arbind,
Just realize... when you run it in foreground, you have a foreground to capture the file location. so it runs fine..
but when you are running it in background, there is no foreground to check that is no gui present... how can it check where the C:\.... location is??
no need of reading any oss note... just see.. the name is cl_GUI_FRONTEND_service.. its only for front end..
u need open dataset, read dataset, close dataset kind of things while running in background. or RFCs to read the file... (search SDN).
