About

Gets or sets the value indicating whether database schema is invalidated when user creates new report. If CacheSchema is set to true, InvalidateSchemaOnNew ensures that the user will see the latest schema information (useful if custom columns and tables are in use) and that new reports (especially if you are using DatabaseAdHocConfig and/or any ReportSet overrides) will appear in the Report List immediately. The DatabaseSchema object is cleared from cache as soon as the New button is selected.

Default Value: False
