Reports are run directly against the data source so that they reflect the latest data. However, viewing the most recent data may not always meet your needs. You may want to view older data. For example, you may want to compare monthly sales volume for a product before and after new features are added.
The report output is saved when a report runs in the background. A report cannot be viewed at the time it is run when it

Report output versions are listed by report format . By default, the
list contains report output versions for the language that is defined
in your content locale. If no reports versions are found for that
language, report formats for all languages are shown.
If burst keys are used, they appear next to the report format sorted by burst key and then by language.
You can specify how long you want to keep report output .
