averages, counts, and other group (aggregate) values. For example, in a
sales report you may want to calculate an average of sales per state (average
summary on the sales field) and calculate the number of products sold in the
state (distinct count of the product name field).
Using the drill-down option on summarized data
You can drill down on your data, to show the data behind individual groups,
using the Drill-down cursor. See “Sorting, Grouping, and Totaling” on
page 167.
Drill-down cursor
Crystal Reports allows you to drill down on group or summary information in
the Preview tab in both the Standard and the Group Tree view (See “Standard
view” on page 91 and “Group Tree view” on page 92). When you position the
cursor over any summary value that you can drill down on, the program
displays a Drill-down cursor.
Tip: Group headers appear on the Drill-down tab just as they do in the main
report itself.
If you then double-click, the program reveals the details behind that specific
summary value. For example, if the Drill-down cursor becomes active over
the city summary, you can double-click to see the details behind that
summary.
• If you have only a single summary, you can look at the summary or at the
data from the individual records that are summarized.
• If you have multiple summaries, you can look at the summaries behind
summaries (the city summaries that make up the region summaries, for
example), or at the data from the individual records that are summarized.
Using the zoom feature
You can easily zoom in on a report. You can choose any magnification from
25% to 400%. This feature is active in both the Design and Preview tabs.
To zoom the report in or out, set the zoom level in the Zoom Control box found
on the Standard toolbar.
