When you place a nested report in another report, the two reports can be independent of each other or they can be related in the database sense by sharing some common data such as a customer number or a department number. If the reports are related, you need to do some extra things to both the base report and the related nested report.

Usually when you place a report within a report rather than create a composite report, you want to relate the reports.
