Hi Kavitha
Welcome to SDN.

Hi Kavitha,
follow these steps:
1.Create a new WD Project.
2. Right click on models and select create model.
3. Select import Adaptive RFC Model.
3. Give any name and package to your model.
select WD_MODELDATA_DEST/or if you have defined any other name for
your JCo destination for default logical system name for model instances.
select WD_RFC_METADATA_DEST /or if you have defined any other
name for your JCo destination for default logical system name for RFC
metadata.(These JCO Destinations are created in portal)
4. Select single server/Load Balancing as per your system.
Give name, system number, client, logon name, password and language of
your R/3 system.
5. Search for the BAPI name and select the BAPI on search and click NEXT.
You have imported RFC Model by this time.
Now create a WD component and then you will find Used Models. Select the name of the model just created above.
6. Open Data Modeler(Right Click on your component name and select Open Data Modeler). Do mapping here from model to controller and from controller to view as per your requirement.
7. To execute BAPI create an element of the input node of your BAPI, set any parameters if required and bind it again to the input node.
say if name of your input node is input
IPrivate<viewname>.IinputElement element = wdContext.nodeInput().createInputElement();
element.set<parametername>("<value>");
wdContext.nodeInput().bind(element);
8. Last step is to execute BAPI
try
{
wdContext.currentInputElement().modelObject().execute();
//say name of your output node is output
wdContext.nodeOutput().invalidate();
}
Bind your output node the one that is found inside the input node to table or other UI element so that you can see the result of the BAPI after its execution.
Warm Regards,

Hi Kavitha,
Please go through the below link which is a presentation on how to use the Adaptive RFC model.
Along with Adaptive RFC model there are different types of models like Web Service Model and Java Bean Model.
If you can tell which model you want then I can send you the steps how to create and use it.
Thanks,
Suvarna.
