When you create a Top Mover report, you rely on the successful capture, aggregation, and storage of the underlying data. The variations in this data are then calculated and stored, becoming available for reporting. While you use the Top Movers page to add movers as soon as they are created or to combine multiple movers for any focus date, the underlying data might not support the report.
Data collection and time zones
The time zone of the Report Server must match the time zone for the Tealeaf system. If the time zones do not match, then no Top Movers data is collected and nothing is displayed in the Top Movers report.
When you configure a Top Mover, it may take a period for data to be collected for the Top Mover so that they can be displayed in the Portal. Hourly Top Movers are collected once per hour, and daily Top Movers are collected once per day.
If after a 24-hour period the Top Movers data is still not collected, change the time zone of the Report Server to match the Tealeaf system time zone.
No data in the report
It can take at least two weeks after a mover is created before it is populated with sufficient useful data to populate a Top Movers report. If the report is blank, the combination of movers and focus date results in no available data at all. If there is no data in the report, change the date range. If you cannot find a date that contains mover data, you must review the date against the creation date for the mover in the Change History dialog. Through the Report Builder, you can create a simple report to verify that the source events or dimensions are populated with data for the selected focus date.
If the report contains multiple movers and one of the movers lacks data, the data for the other mover is still displayed. Try removing the mover that contains data to see whether the preceding error message is then displayed.
If you cannot find the mover to add, verify that you selected the correct type of mover to add. Only Hourly movers are displayed if you are using Hourly movers in the report page.
Report display limits
If you add a Top Mover or dimension and the total number of potential rows to be displayed in the detail table exceeds 1,000 rows, a warning indicates that report performance can be affected. If the warning is ignored, the Report Builder attempts to query and display the report. If this row limit is indeed exceeded in the returned data, the report is not displayed. If the warning is canceled, the proposed changes are maintained so that you can apply filtering to reduce the scope of the report.
