RFC call from a Windows Service

[former_member583013]

Hi All,

I have created a simple windows service which is making an RFC call to R/3 system. This is not working. Whereas the same piece of code written in a windows application projects(exe) works properly. Does anyone had similer issues working with Windows services ? Is it a known issue of RFC calls from windows service ???

Thanks & Regards

Hi Juergen,

After I put the debug statements I figured out that connection to R/3 system is unsuccessful.

I am using the SAP .Net Connector 2.0. I wrote a windows service which is manually started. Withing my service I am using Single sign on to connect .This is what was causing the problem. If I disable Single sign on and supply userID and password then connection is successful and also subsequent RFC calls.

I guess within windows service Single sign on does not work.

Thanks for your reply

Best Regards
