What are subreports?
A subreport is a report within a report. The process for creating a subreport
is similar to the process of creating a regular report. A subreport can have
most of the characteristics of a report, including its own record selection
criteria. The only differences between a subreport and a primary report are
that a subreport:
Is inserted as an object into a primary report; it cannot stand on its own
(although a subreport can be saved as a primary report).
Can be placed in any report section and the entire subreport will print in
that section.
Cannot contain another subreport.
Does not have Page Header or Page Footer sections.
There are four instances in which a subreport would typically be used:
To combine unrelated reports into a single report. See Combining
unrelated reports by using subreports .
To coordinate data that cannot otherwise be linked. See Using subreports
with unlinkable data.
To present different views of the same data within a single report. See
Showing different views of the same data in a report.
To perform one-to-many lookups from a field that is not indexed on the
lookup field.
For more information, see "One-to-many links" in the online help.
Note:
You can increase the performance of reports containing subreports by using
on-demand subreports instead of regular, in-place subreports.
