The easiest way to create a custom report is to copy an existing report, then customize the SQL query string as desired. To customize the SQL query string, you may need to refer to the data schema, which describes the organization of information in the relational database. The data schema for each standard report is available in the Console by opening the report and clicking Help.
Even if you cannot edit SQL, saving a report as a custom report lets you re-use the report data without having to re-input the parameters in the standard report.
You can also define custom reports from a blank template and input the SQL query string directly.
When you create custom reports, you can enter a category and use it to group the reports any way you want.
