How to show Bex Queries in Browser

Hello Experts,

when i try to execute a Query from the Bex Query Designer to be shown in the Internet Explorer, an address like this is generated:

http:///irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fplatform_add_ons!2fcom.sap.ip.bi!2fiViews!2fcom.sap.ip.bi.bex?QUERY=ZISBNCAT_Q0001&VARIABLE_SCREEN=X&DUMMY=2

As you can see, the server is not inserted properly after http://

When i enter it manually i get a 404 error (The requested resource does not exist.).

What steps do i have to undertake so that Bex Queries can be shown in the Internet Explorer?

Kind regards,

Tanja
