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
unrelated reports by using subreports
.
•
To coordinate data that cannot otherwise be linked. See
•
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.
