Integrating SAP BO 4.1 in SAP Netweaver Portal 7.3

Hello Experts,

I have requirement to integrate SAP BI 4.1 SP4 in Netweaver Portal 7.3 SP4.

for this

• created a URL iview , have given the correspoding url of BO launchpad.
• Assigned this url iview to a role
• Assigned this role to the user
• SSO is enabled between BW & BO
• SSO is enabled between BW & Portal
• to enable SSO between Portal & BO I have imported the SAPLogonTicketKeypair-cert of Portal in BO (C:\SAP BusinessObjects Enterprise XI4.0\java\lib ) where we generate the Certificate to establish SSO between BW & BO

now when the user  login into Portal and click on the url iview he/she is navigating to the Login page of the BO (i.e system is prompting for Password)

Could you please let me know if i missed anything  ?

Many Thanks
