Hi,

RFC and BAPIs are remote enabled function modules. They are practicly the same. A BAPI is one step further as it usually is a self contained business function, such as "Create Purchase Order", or "Change Sales Document". BAPIs interface is very well defined and documented. BAPIs can be found in the BAPI browser via transaction BAPI. RFCs are just remote enabled function modules.

BAPI performs a complete business application like customer creation,material creation as it is encapsulated with business object.

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

Raj.

BAPI is transaction related where as RFC is Cross system realted.

By using BAPI you can save the transactional data

Like PO creation or Account Document creation those things you can do it.

RFC is For Communication kind of thing Between two systems.

We will take one example where we have to post the account document in other system.

I will use the RFC BAPI function module to post the document.

Here in this case I am using the BAPI function module for posting the transactional data By using the RFC connection.

Hope you understand the concept.

Reward Points.

Madan.

Hi,

BAPIs are RFCs, the only difference is that BAPIs usually encapulate some complete business object. For example, creating a sales order, the BAPI would do all of the steps required to create a sales order.

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
