To create a new report definition by making a copy of an existing report definition, mouse over the report definition (or select the check box next to the name) and click Copy.
The interface displays the report definition editing page with a message indicating that the new report was created. The name of the new report definition has a number appended to the name of the original report used for the copy operation.
After the editing page appears, you can make changes to the definition just as you would to any other report definition in the repository. Because the default report name is not very informative, change the name to something more meaningful.
