Dear Masa,
Thanks for your response.
I have looked into your documents, but the scenario is from SF to SAP NW GW.
I have already thought of implementing the Apache Reverse Proxy for Fiori so that it can be accessed from the cloud like SF but that would not serve the SSO which i am looking for using SAML.
If you can point out the steps it would be great.
Thanks,
