how to refresh the Dashboard to get the latest data

Hello Experts,

I have created Webi report from Universe designer and then built the dashboard ( using Xcelsius Dashboard 4.0 designer) through Live Office Connection. I can save the webi reports and dashboard on to BI Launch Pad.

Everytime when I open the Dashboard it should fetch the latest data which is available.

Can anybody suggest how to achieve this?

Regards,

Naresh
