Managed System Configuration Super User Issue

Hi folks ,

I have a strange error in Solman SP8 Managed System Config .

In Step 5 : "Enter System Parameters" , for entering super user , it throws an error even though the user credentials are valid.

This happens for some of the managed systems only . The error says : " Issue with connection to system <SID> <Client>".

It does not seem to be using the right RFC and I feel it is checking for the user in 000 client , regardless of which client we give . Because if we give 000 credentials it works.

Please help . As without this I cannot save any of the system parameters like Load Balancer URL etc.

Thanks,
