Use the powerful My Reports feature to save report definitions that you can generate at any time. You can then generate the report without having to define your report criteria again.
To save a report:
Create your reporting criteria and generate a report.
Select File > Save.
Enter a name for the report. The report will be saved under the user name (for example, Dave's Reports) sub node in the My Reports node of the function tree.
