Precalculated webtemplate/Authorization problem

Hi BW experts,

I've precalculated a webtemplate in excel format and am downloading the same using Download Scheduler. I'm able to download the excel reports onto my local pc, but the result rows are not being displayed, instead the excel contains the text <b>'No Authorization'</b>. Could some one please suggest how to resolve this or what is the corresponding authorization object for this problem.

Your help will be greatly appreciated.

Thanks

Sanjay
