Is there any problem with RFC connection with OrgChart?

Hello Gurus:

I am trying to see if my HR-OCI connection is properly set or not (as I have a Live connection for Org Chart 5.1.31, Nakisa 2.0) and one of the pre-requisite is that RFC connection (SM59) should be set up. But I am not sure what exactly should it read there? Should it be under ABAP Connections, or HTTP Connections to External Server, or TCP/IP Connections? I could not find an entry which resembled Nakisa/OrgChart.
