Its not possible to run front end services in back ground.

For back ground equivalent check http://scn.sap.com/thread/1431755

but my requirement is only for presentation server

because i work on two different system one is sap and another is .net base system

my .net system download file on  '\\192.168.1.86\OUT\BINNING'

and i pick up the all file form that path and update data is sap system with no user interaction

Hi,

If that's your design then you can use background processing. You can download the file in desktop move it to application server then use the path in the application server to do your background processing.

Cheers,

In that the only option is that .NET application should write file on application server if you want to run your program in background.

Hi Mayur

U can run the frontend services even in background.

I have debugged below code in background.

I kept breakpoint keywor before call method statement and go to sm37 select the job and f8.

You can see the job then select the job and in command field use jdbg and press enter which enters into debug mode of background job. Press f8 now the breakpoint keyword in ur program triggers.

I think there is a problem with the directory path.

Its working in my system with my own path(directory).

BREAK-POINT.
