Format RFC communication

Hi all,

I already posted this question in another forum, however, the answer was not quite 100% satisfying. That's why I want to try my luck here.

We're doing RFC calls between our SAP CRM system and an external application (non SAP). We had a discussion about the actual format of the RFC's. One person said the format is XML, while in my opinion it's not. But suppose I'm right, than what is the actual format? It's not EDIFACT, (flat) file etc., but....The communication is done via RFC libraries, and for 'all' sorts of platforms there are different libraries (correct me if I'm wrong). But, still, I don't know anything about the format (if any at all).

When I look at the gateway, we can see some hexadecimal data, but I quite positive that this only the gateway logging format and not the RFC format. Anyone who can shed some light on this......anyone at all.

Kind regards,
