Hi,

To give u a brief idea.

rfcs are used to call data from the backend that is R/3.We use the Bapis from the R/3 system which have some pre defined functionality and data is populated in the correspoding ui elements in webdynpro interface.earlier Rfcs were used but now we have adaptive rfcs in which

if there are changes in the backend(R/3 system) such as changes in the datatype,structures,fields would be automatically be refllected in the rfcs and there would be no errors in web dyn pro even if there is a change in the back end

to be more specific folow this link

http://help.sap.com/saphelp_nw70/helpdata/EN/41/38bc8f813719488ddc9d9b21251ec3/frameset.htm

Relation ship Rfcs in the R/3 system are created in the form of Bapis this Rfc is imported in webdyn pro project as an model

1.Now a bapi has input as output parameters

2.these input parameters are mapped to a view in web dynpro

3.when u supply parameters to the rfc model imported it sends the values to the bapi at backend an corresponding data is given to bapi output parameters.

4.these output parameters are mapped to the result view in webdynpro thus u can see the data from R/3 sytem.

Now inthe newer version rfcs are called adaptive rfcs.the older concept of rfcs has been erased.

and try out this application

to use the rfcs firstly check out this document for configurations

Hi Ramachandra,

RFC- Remote Function Call. It implements business logic in ABAP in backend system and makes it available remotely.

Adaptive RFC Model -is a technology that enables the Web Dynpro application developer to use the business functions encapsulated in Business APIs (BAPIs) or RFCs even after a structure modification.

WebDynpro development components - is an individual entity that can be executed.
