Hi Punit,

Follow the two things

1. Make sure that the JCO you are using is working fine.

Check that the userid and password is still valid.

2. Check whether the RFC is working fine or any changes happened? Log in with the user same as portal and then execute the RFC.

3. Restart your server and NWDS.

it will solve your problem.

thanks

Punit,

did you check the trace in st22.

It seems like a backend problem not the frontend

Thanks
