Save your report settings so you can run the same report with the same settings again.
This just one of the dozens of little "make life easy" features. Memorizing reports is an odd term coined in the early era of Quicken and QuickBooks. It's been around for twenty years, and means to save the filter choices used to run a report.
What is filtering? When you run reports, you naturally want to filter the report so you see only what you're looking for. You don't want a 100-page report with everything. Instead, you want just the relevant data for your application. So, you filter the report. In plain English, you make choices that trim the report down to size. Instead of a 100-page report with everything, you get a 2-page concise report for just your client or project.
The problem come in when you run a certain report many times. Each time, you have to remember the filter choices to get the report you want. Sometimes you forget. Sometimes you pick the wrong choices. Sometimes you pick too many choices. The end-result is that the report looks similar to what you want, but may not include everything or may include too much. What you really want is a way to "memorize" those report options.
That's what Memorizing Reports is.
When you run a report, simply choose the report options you want and then click the "Save" button. That saves all those report options to a file on your hard drive. The report shows up with a special "filter" icon in the upper-left. If you click that icon, the report opens immediately, without any other dialogs getting in the way. That's single-click reporting!
