Using the Group Sheet
Use the Group sheet of the Profile Properties dialog to update group properties.
In the JADE Report Writer Designer application, groups enable you to group your data under various headings and produce subtotals when a group changes. For example, if a customer report is grouped by customer, each group could show all purchases made by one customer with a subtotal showing the total purchases for that customer.
As groups are defined on report fields, creating groups is not an administrative function that you can do initially. Creating groups is therefore described in "Creating Groups" under "Using the Detail Functions", later in this chapter.
