Recently our lead architect, venkiteswaran.balakrishnan, wrote a sample app that demonstrates the flow to get an OAuth Bearer token based on a SAML2.0 assertion for an SAP Cloud for customer tenant. The token obtained can be used for SSO during OData services offered by SAP Cloud for customer tenant. If you are exploring SAP Cloud for Customer's OData services, then you will want to try out this OAuth sample!
