When your are building HomePages, I recently wrote a about using Favorites to save the complete URL and be able to use it later.
Build your specific Pivot Analysis and and click on the Favorites icon. The URL will display all of your criteria so that when you deploy this to a HomePage, the view will be exactly as you designed it. I find that I often have two or more Pivot Analysis Views on a single HomePage.
Using this function means that you do not have to tweak the criteria, unless desired to view your information.
