hi,

Remote Function Call:

RFC is an SAP interface protocol. Based on CPI-C, it considerably simplifies the programming of communication processes between systems.

RFCs enable you to call and execute predefined functions in a remote system - or even in the same system.

RFCs manage the communication process, parameter transfer and error handling.

BAPI

BAPI stands for Business API(Application Program Interface).

A BAPI is remotely enabled function module

ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..

You can make your function module remotely enabled in attributes of Function module but

A BAPI are standard SAP function modules provided by SAP for remote access.

Also they are part of Businees Objest Repository(BOR).

BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects.

You create business objects and those are then registered in your BOR (Business Object Repository)

which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA.

In this case u only specify the business object and its method from external system

in BAPI there is no direct system call. while RFC are direct system call.

Some BAPIs provide basic functions and can be used for most SAP business object types.

These BAPIs should be implemented the same for all business object types.

Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs.

Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.

HI KReddy,

BAPI is grouped under a business object as a method of the business object.

Where as RFC is just a Call or a function module.
