Hi Faraz,
You would need to use Open Document Url reporting, or use the crystal report processing server service using the java sdks to view crystal report for enterprise reports. Or else use Restful webservices as suggested by Dell.
You would not be able to view crystal report for enterprise reports using the RAS SDKs, as it is not supported for this version of reports.
RAS SDKs can only be used for CR 2008/2011/2013 designer created reports.
Thanks,
Prithvi
