Can the BO client tool run in 3-tier mode?

Hi,

Does anybody know if it is possible to run the BO client tools in 3-tier mode during the desing of reports and universes?

As far as I can tell the client tools (Webi desktop, UDT, IDT, Crystal reports) will in design mode always try to access data directly (1-tier mode) using the database middleware installed on the client.

However, I wonder if it is possible also to run design of reports and universes in a 3-tier mode where the client tools will fetch data via the BO platform and not directly from the database.

Any ideas / input?
