SSO issue with BI 4.0 BW and ECC

We currently have SAP BW 7.3 BOBJ 4.0 ECC and SAP portals.

We have configured SAP BW, BOBJ and SAP Portal with SSO and that works perfectly fine.

The issue is that i have Crystal Reports running on ECC that have also to be published to the Portal.

All BW crystal reports run fine and ECC fails because of SSO -

What am i missing here -

Do i need to do something different for ECC

In CMC Authentication i have added SAP ECC and imported a role - So now i have 2 ids - one from BW and the other from ECC.

I know this is not the way to do it but it still does not work.

What do i need to do to have ECC and BW reports to work with SSO from SAP portal.

Thanks
