It seems to be because of the use of FM GUI_UPLOAD. You cannot upload a file from presentation server in background..

Try keeping your file on the application server, pick the file from app. server in your program using Open dataset and then try running the program in background.

Hi,

Do you want to just run the program in background? If so then just create a variant and create a background job - I'm not sure you want to be calling the BAPI as a seperate background task?

HI,

Your problem is not with the BAPI function module, with the GUI_UPLOAD, because it is not working in back ground, only working in foreground. Do one thing try to get the data from application server instead of desktop when program is running in back ground.

Hi,

Abhishek's answer is true,in ur code u ar using GUI_UPload this fm is are dependent on the gui

You can not use these in the background. You must download to the application server, using the dataset statements.

OPEN DATASET

TRANSFER

CLOSE DATASET

Hi,

I'm a bit confused now - does the BAPI call work if you run it entirely in foreground or does it fail there too?

You need to ensure your BAPI works correctly with the data you are passing to it - preferably in foreground so you can debug it and see what is happening. If it throws errors there then add them to this thread.

If it works in foreground then you probably need to schedule the job in background but as others have pointed out, you can't use the GUI_UPLOAD function to do this.
