RFC Interface
The RFC interface is required to execute a remote function call. The RFC
interface performs the following services:
Calling and controlling the communication routines needed to communicate
with the remote system
Logging on to and log off from the remote system and authorization
checks for the function groups used.
Converting actual parameters to the format required in the remote system
and vice-versa. This includes any platform-dependent conversions (for
different code pages or byte sequences for
example). The conversion supports all ABAP data types.
Handling any communication errors and forwarding them to the caller if
requested .
If the AS ABAP are not the same, two ABAP programs communicate
using the RFC interface, whereas for communication between an
AS
ABAP and an external system, an ABAP program connects with a program
in another programming language (C, C++ , Visual Basic ,
Java or .NET ).
For communication with programs in other programming languages, RFC
libraries are available for all operating systems supported by SAP,
including MS Windows , Unix and Linux :
Java Connector ( JCo ) for Java
.NET Connector for .NET ( C# , VB.NET )
RFC Software Development Kit ( SDK ) for C and C++
Note
Each RFC that runs across the RFC interface on AS ABAP runs in
its own user session. The logon data is usually stored in the RFC
destination.
