Format RFC communication

[Sm1tje]

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,

Micky.

Hi,

Maybe this will help "The RFC call to Windows follows the OLE standard, while UNIX is connected via TCP/IP RFC which is a standard in all TCP-compliant systems." Got it from the link: Link: [RFC|http://logosworld.de/www3/cookbooks/rfc/comm_40_rfcexec/docu.htm].

Finding the exact definition of RFC Protocol would give better results.

Regards,

Sai

Hi Micky,

What i can think of id BAPI. You can wrap the RFC in the BAPI and expose the business object method. This method can be adapted by the non-SAP application using OO technique (via C++ or any OO concept).
