While clicking on Additional Fields does not do anything, this item is actually an expandable folder. Within this folder are two items; Field Labels and Field Group. More will be explained about both of these items in their respective pages. These two items can be created for an Expense Type or for a Report Type. Once they are set up, they can be attached to either. More will be covered on attaching these items later on in the Report Type and Expense Type sections respectively.
