Error while executing a query

Hi,

When I am executing a query from Bex Query designer , a web browser opens with an error

"Address is not valid"

The URL displayed is: 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=0D_SD_DEMO_Q0001&VARIABLE_SCREEN=X&DUMMY=1

Please let me know the procedure to change this URL on the BW system.

Thanks,

Shahid.
