Using BIWS connection in Dashboards designer

Hi,

I have created a Webi report which has 10 colimns in it as per my requirement and published it as a Web Service.

Now i have used QAAWS connection and imporetd the above Web Service into Dashboards designer.

so now i have all my 10 column in Input values section in the QAAWS connection window.

My question is now how do i map all these 10 columns into the Dashboard's embedded excel spread sheet.

So that when i preview my dashboard i should see all these 10 columns.

Kindly if any body know the steps please send me the details steps to be followed.

Thanking you,

Regards,

Nanda Kishore.
