The purpose of container reports is to place the output from multiple reports within a PDF container and and allow the user to print, email or store the document. There is a process to follow in preparing container reports that is more fully described in the User Guide. As well as being able to place multiple reports within a container, you can use a special method to combine the output of several summary reports onto a single layout, and then place the results into the container report.
The above diagram represents how a report such as the one shown below can be prepared.
