Hi Bharath
As mentioned by RB in the above document link , all the set up steps are present .. Few critical things :
a) Ensure that the RFC Destinations are working fine between the 2 systems . from the error shown above , the sapms entry is missing in the services file.
b) Also for Trusted connection to work , you will need the user ID which has the S_RFCACL authorizations for the login credentials in the RFC destinations. Else the trusted system will not work.
Let us know how you proceed ...
Thanks
Rishi
