Hi Ulrich,
Thank you for your response.
After implementing OSS note 1969140, object missing in WSDL error is eliminated.
Then, I used report RSSIDL_DESERIALIZE_DEMO to validate WSDL but getting an "unknown name space error".
Looks like there is an issue with WCF WSDL and am checking with .Net Team.
Keep you posted if any solution is found.
Thanks
Shan
