Start BPM with RFC

Hello,

as there is no chance that a BPM starts by itself I want to start it by a RFC from R/3. I have no idea how the RFC has to look like.

I have set up a sender agreement with a rfc-sender (communication channel). I defined this sender in ta:sm59 on our XI with TCP/IP (connection type T) and it seems to work properly. But how do I get the connection between the RFC and the sender-agreement?

Regards.

Oliver.
