Hi Ashwin,
Actually SAP has only provided that extension points for all the Fiori Apps and as standard Apps utilize the standard services and so I am extending them them as per the requirement and so that I can extend standard Fiori app. My main issue was that as per the SAP Documentation I have already extended the structure and have added the fields in that structure and also implemented the data provider code for it but the problem is that as I have not changed the model provider class for that particular extension that fields don't show up in the xml document when I append metadata to that particular service.
Regards,
Fenil.
