Once you are familiar with the Select Expert and formulas, you can use your record selection techniques to improve the performance of your reports. For additional performance tips and advanced record selection strategies, see Using enhanced record selection formulas.
When you select records, you are basing your report only on those records that meet some conditions that you have set. You base those conditions on the kind of information you want in the finished report.
Assume, for example, that you want a report that only shows data from California. The challenge is to find the best way to identify those records that come from California.
