BAPI VS RFC?

[Former Member]

Hi,

Can anybody please tell me what is the difference between BAPI and RFC?

[Former Member]

It is true that BAPIs are always defined as Remote-enabled function modules. However, what makes them different or conceptualized in a particular class as "BAPI" is that they serve for a business related functionality as the name also implies "Business Application Programming Interface".

hi,

both BAPI and RFC are function modules which can be called via an external system.

BAPIs are a set of FMs that are already available whereas RFCs are the customised version which is coded by the user as per his needs.

Hi,

RFC - Remote Function Module - every function module which its attribute "Remote-enabled module" is checked is considered to be a RFC.

BAPI - a private case of RFC .A BAPI is an abap module function which fulfils specific design criteria.

A BAPI must:

1. Have a name that starts with BAPI_

2. Maintain a static interface through different versions

of the sap system

3. Be remote enabled

4. Handle all errors gracefully

5. Implement the method of a SAP Business Object

etc. etc.

Please pay attention that when using rfc function you can't invoke the SAP GUI - only transfer/change data.

Regards,

Ruthie.

HI

BAPI VS RFC

BAPI stands for Business Application Programming Interface. It is a library of functions that are released to the public as an interface into an existing SAP system from an external system.

RFC is the protocol used to call functions in an R/3 system by a caller external to R/3 or to call programs external to R/3 from an R/3 system.

Functions can only be called via RFC, if they are tagged as RFC functions in the SAP development workbench. They are then called RFC function modules. BAPIs are complete sets of (BAPI) function modules that model a business application.

When you are familiar with web developments: RFC can be compared to HTTP and BAPIs are CGI applications.

In other words: A BAPI function is a function module that can be called remotely using the RFC technology.
