Why We Call Adpative RFC MODEL?

Hi Subbarao,

The Adaptive Remote Function Call (Adaptive RFC) is a technology that enables the Web Dynpro application developer to use the business functions encapsulated in Business APIs (BAPIs) even after a structure modification, without having to provide the new data using a second back end or a new structure with subsequent regeneration of the proxies.

This new RFC model shows adaptive behavior. This means that the RFC proxies do not use the original design time structure definition at runtime. Instead, this Web Dynpro model automatically adapts the data of the structure passed in the Java proxy generation to the current data – that is, a structure definition in the back-end system that may have been modified

RFM - stands for Remote-enabled Function Modules, amd you can learn more about it from

Difference between BAPI and RFM --

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.

Hope this helps,
