Hi Raghu,

You can use RFC for conneting a sap system to a non sap system.

bapis are also RFC.

Remote Function Call (RFC) is the call of a function module that runs in a different system to the calling program.

RFCs were a natural evolution of FMs, that could only be called within the confines a single R/3 system, to being able to remotely call FMs defined in another R/3 system all together.

The RFC interface system enables function calls between two SAP systems, or between an SAP system and an external system.

The RFC- interface system is made up of the following interfaces:

Calling interface for ABAP programs

Interfaces for calling non-ABAP programs

Call Function statement is used to call remote function

Syntax : Call FUNCTION RemoteFunction

DESTINATION Dest

EXPORTING f1 = …

f2 = …

IMPORTING f3 = …

TABLES T1 = …

EXCEPTIONS ……….

Destinations are defined in RFCDES table via Transaction SM59

TABELS Parameter : The actual table is transferred but not the table header

RFC supports ‘Call by Value’ mechanism.

RFC do not support ‘Call by Reference’?

The first time table is passed, it is given an Object-ID and registered as a “Virtual Global Table” in the calling system
