Grouping Data
This is one of the fundamental constructs of nearly all reports. Data groups provide a mechanism for orga-
nizing data into hierarchies and may be used to create section breaks and subtotals. Groups are used in
different report items to implement specific features. Once you have defined a group in any report item,
you should be able to do the same in any other item, although the design user interface may vary slightly
for different types of items. There is no limit to the number of groups that may be added for any item.

Figure 6-3 shows the Grouping and Sorting Properties for a group defined in a table.
