How do I see categories as a percentage of sales?

On the Data Sheet, you'll see a  % and a $ button at the top right, just below Refresh. These allow you to switch between the standard $ view, and a Percent of Net Sales view.

When you click the % button, all the numbers on your data sheet will convert to showing what percentage of Net Sales those numbers represent for the department you are looking at.

Click the $ button to switch back.
