| |
| − | * The first time a report is viewed, it will be created by querying the database and live data will be displayed.
| |
| − | * Anyone viewing the report after this and within the life span specified will see a snapshot of the report from the cache. Changes to underlying data will '''not''' be reflected in the report during the '''Cache Life Span'''.
| |
| − | * The report will be updated once the life span has expired, and any changes to the underlying data will then be reflected.

| |
| − | * Cached reports that include criteria based on the current user (i.e. '''@userid@''') must be '''Cached By User'''.
| |
| − | * In general, sub-reports should not be cached. The parent report can be cached if appropriate.
