If your report in the Power BI online service is not updating the date slider according to the dates in the data source after a refresh, there are a few things you might want to check:
- Data Refresh Settings: Ensure that the data refresh settings are correctly configured. You can set up a scheduled refresh or perform a manual refresh to ensure the latest data is being pulled into your report.
- Date Column Configuration: Verify that the date column in your data model is properly configured as a date type. If the column is not recognized as a date, the date slider may not update correctly.
- Automatic Page Refresh: If you want to keep fetching the latest data changes from the source, consider configuring automatic page refresh for your reports. This can help in ensuring that visuals, including the date slider, are updated based on the latest data.
- Data Source Compatibility: Ensure that your data source supports the type of refresh you are trying to perform. Some data sources may have limitations on how they can be refreshed in the Power BI service.
If these settings are correctly configured and the issue persists, you may want to check for any specific error messages or warnings in the refresh history that could provide more insight into the problem.
