Inbound RFC adapter question

Hi,

I'm trying to configure this scenario properly

CRM 4.0 <--

> Legacy system

using:

Synchronous <---- -> RFC / SOAP < ----> Legacy

RFC call Adapter / Connector system

I want to configure the RFC destination on the CRM side using SM59. I've created an RFC destination of type T TCP/IP for the RFC adapter. My question is: what is the program ID?

In the documentation, I found I should put in there the Program ID from my RFC adapter configuration file. Would that be the Rfc2XmbService? I've tried that but when I test my connection, I get an error message saying that the connection could not be established.

I'd really like to know how I can configure a destination on the sender side that points to the right RFC adapter...

Thanks a lot for your help!

Best regards,

Nathalie.
