RRMX/SSO not working with Win7/GUI 7.2

Dear all,

I'm testing the useability of our BW system with new Windows 7 and SAP GUI version 7.2.

The only way of launching BEx analyzer is via RRMX or portal (using single sign-on) but this is not working. Once i trigger RRMX, Excel 2007 is opened (with Business Explorer Add-In) but when i try to open a query it opens the SAP Logon! The BEx version used is still the 3.5 (but we are in SAP BI 7.01).

Does anyone faced this problem? Do you know if there are specific settings for using SSO or RRMX with GUI 7.2/WINN 7?

Thanks for your help.

Best Regards,

Nuno
