Hi Stefan

Are you trying to use an RFC of type T?

https://wiki.scn.sap.com/wiki/display/ABAPConn/Activation+Types+for+Type+T+RFC+Destinations

If yes, the external program has to be registered to the SAP gateway first before the RFC will work. You can check this in transaction SMGW - by going to "Logged On Clients" in one of the upper menu's. If the program isn't registered, youi'll need to take care of this first and figure out if it cannot connect to the gateway, why that is. Check log files on date/time stamp after attempting.

Best regards

Tom
