SSO Portal to BO inside PortalComponent

Hello,

I use Portal to BO Integration for accessing Reports through iViews. We operate SSO from Portal to BO, works fine.

I successfully use BO SDK to logon to CMC in a PortalComponent like this:

IEnterpriseSession enterpriseSession = sm.logon("TB6~800/KAMM", "welcome", "twdf1567:6400", "secSAPR3");

My question:

The User TB6~800/KAMM is allready loged on to Portal and may call Reports from BO with SSO.

Is there a way to use this Portal to BO sso for fetching an enterpriseSession inside PortalComponent - Coding ?

Tnx for any tips

Johannes
