Dear All,

As BAPI itself is an RFC, how it is different from normal Function Module? How it can be used from other progrmming language to connect to SAP?

Thanks in advance,

Prasad.

HI!

BAPI-s cannot be called from an RFC connection, if they are not enabled for it. It can be enabled in the SM37 transaction, Properties page - Remote enable radiobutton.

If they are enabled, you can call them from outside also.

If they are not, you can create an own Z* function module, which calls the BAPI with the same parameters, and is enabled to RFC.

Hi,

Difference between RFC and BAPI

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.

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.

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.
