This is easy,

You have to update your services file on your host with correct service name and port number.

Also update your host file with hostname and IP address of your target RFC system.

Hi Amit

You can resolve the system name either by IP or Host name ? Could you check the DNS server or Local host file

Hi Sriram,

could you please more specific about this? do I need to check local file in GRC system or it has to check in ECC as I am creating RFC ECC to GRC?

Do I need to enter in services file in my PC?

Hi Amit,

Please add following entry in the services file of GRC as well as other SAP system from where  RFC is initiated.

sapms<SID>   36<NR>/tcp

Take a restart of SAP application to clear the buffered entries and then check RFC connection.

Hope this helps.
