TCP/IP connection

[Former Member]

Hello,

How does the TCP / IP connection between R3 and XI when they have a RFC sender communication channel?

I don't understand how R3 knows that must communicate with XI because the SM59 does not tell you the IP of XI

thank very much

Hi,

>>How does the TCP / IP connection between R3 and XI when they have a RFC sender communication channel?

To understand this I will suggest you to first create a TCP/IP connection between R3 and XI and then create a Sender RFC channel with the same program listener.

If both are available then now

1. stop RFC sender and do test connection

2. delete RFC Destination and see RFC sender log

in both cases it will throw an error, that means a RFC listener is waiting for the request sent by R3 using the registered RFC destination (TCP/IP type).

So like this they identify each other!!!!
