DesignStudio: Open a Connection for DataSource failed

Hi all,

i have a problem if i selected a OLAP Connection with SSO, i get the following Error Message >> Failed to obtain SAP Assertion Ticket for connection "xyz". Check the server-side SSO configuration for user "abc" <<.

If i use this connection for excample in Analytics for OLAP it works fine.

Any idea?

Thanks

Andy

PS: I use BO Design Studio 1.1
