Issue in SSO between EP and GRC AC 10

Hi Folks,

Posting this weird issue regarding SSO to SAP GRC AC 10 from enterprise portal. After having configured SSO from SAP Enterprise Portal to SAP GRC AC 10, the GRC landing page opens up fine, with links enabled as per the logged in user. However, clicking on any of the hyperlinks – Work Inbox, Access Request etc – results in the error : "Page not found or not available". Refer attached snapshot. Any thoughts on what this could be due to, and how we can resolve this ?

Thanks,

Veena
