One of the more powerful features of Report Studio is using Grouping with the bands to create grouped reports. What this can allow you to do is group data into sub categories based on a common field in data. For example, let's say you want a list of all of the invoices that you've made, and each invoice has each line item for that invoice below. What you can do in this situation is drag in your invoice line item fields into the Body band, and then use the Band Editor to group by Invoice ID. When this group this, you create a Break band above the body and a Trailing band below the Body. The break and trailing bands can be used for information about the Invoice in this instance, for example putting the customer information and purchase date on the break and the total for the purchase on the trailing band.
