How to MAP change in backend data to UI in Webdynpro java

Hello All,

I have a doubt. Suppose we have WDJ application with Adaptive RFC. We are displaying some data in a UI in table. The table data is getting populated from SAP system RFC-> Compont Controller(WDJ)->ViewController.

Now if some additional fields get added in SAP backend (ECC) system data and we need to show the same in WDJ Table. Do we need to remap and add addtional context attributes ? I want to know like how to accomodate changes in data source to UI in WDJ. No matter what the data source be RFC, webservices etc..

Thanks

Uday
