Hi ambica,

i understood your answer but what exactly my doubt is,

what is the difference between normal RFC model and Adaptive RFC model.

And difference between normal Webservice model and Adaptive Webservice model.

and which is suggestable to use when ?

You are saying something about structure modification can you explain it in detail like how it is possible to do

Hi

A normal RFc model do not show adaptive behaviour i.e If there is a new entry in your structure and if you try to deploy the application it will give you an error whereas an Adaptive RFC model is flexible to that and it will adapt to changes in your structure(BAPI/RFC).

The same is with webservice and Adaptive webservice model.

It is preferable to use a model which shows adaptive behaviour.

go through the following link

hope it gives you more clear idea on arfc model

Hey, where did you see "normal RFC model"?

AFAIK, RFC model is always adaptive, i.e. it adapts to back-end compatible changes (extensions). Though, this is surely quite normal

Hi

Model are used for connecting to backends.

Adaptive RFC Model is exclusively used for connecting to R/3 System using BAPI'S. they show an adaptive behaviour that is they are flexible to the structure modification.

Webservice Model is used to connect any backend provided you need to have WSDL file. R/3 systems can also be conected Using this model but the BAPI's must be created as webservices i.e WSDL file. they donot show adaptive behaviour.

Adaptive WS model is the new which is adaptive to the structure changes.

for adaptive RFC model
