To reduce the performance impact of generating sales reports, Magento calculates and stores the required statistics for each report. Rather than recalculate the statistics every time a report is generated, the stored statistics are used, unless you refresh the statistics. To include the most recent data, the report statistics must be refreshed before a sales report is generated.
To refresh report statistics:
On the Admin sidebar, click Reports. Then under Statistics, choose Refresh Statistics.
In the list, select the checkbox for each report to be refreshed.
Set the Actions control to one of the following:
- Refresh Lifetime Statistics
- Refresh Statistics for the Last Day
When complete, click Submit .
