RFC function via Delphi..

[Former Member]

Ok, I'm trying to run an RFC function with Delphi..

Well, I did run it successfully, but there is one problem.

I'm using SAP Remote Function Control object to connect to the SAP.

SAPFunction.Connection object cannot connect over router. I set Connection's SAPRouter, GatewayHost and GatewayService and tried to connect but got connection error. Without these parameters I can successfully connect via LAN. What I want to do is connect over Internet.

I can connect via SapGui without problem. Also when I use no parameters then I can also connect via router (It gets its' parameters from "saplogon.ini" and dialog boxes). But I want to set them manually to get instant rfc answer..

Could anybody help me about this?

Oh man ... my memory is fuzzy on this, hopefully others can flesh this one out for me. But, the SAP RFC library needs parameters like /MESSAGESERVER or something like that. I think that on a string where you point to the message server, you can use /H/ to seperate different router hops. E.g.

/H/router1/H/router2/H/messageserver

And you can also use a / flag to indicate the port. Sorry but I can't remember much beyond that, try googling it.

I tried with "/H/router/H/". I will try again with "/H/router/H/MESSAGESERVER" and see what happens.

/H/hostname/S/port/H/

I think I found it, this is how you define the port, in addition to the host file.
