The next logical step is to group the data in some way. You can group it by
region, or by product line. The following section shows a look at both of these
options.
Report of order data - grouped by region
This report uses the data seen in the first report, but here the data is grouped
by region. All the orders in each region are grouped together, but each
regional group contains orders for different types of locks. Because the
groups contain different kinds of data, summarizing the Quantity field will
determine the total number of locks sold per Region, but not the total of each
type.
Each region group contains orders for different kinds of locks.
