This capability is particularly valuable for monitoring dashboards, real-time analytics, and operational reporting scenarios.
To configure automatic page refresh, navigate to the report page in Power BI Desktop and access the Format pane. Under Page Information, locate the Page Refresh section. Here you can enable the feature and set the refresh interval. The minimum interval depends on your data source type and workspace capacity.
For Import mode datasets, automatic page refresh works by refreshing the underlying dataset at scheduled intervals. The minimum refresh interval is typically 30 minutes for Pro licenses and can be reduced to seconds for Premium capacities. For DirectQuery and Live Connection modes, the feature supports much faster refresh rates, potentially as low as one second for Premium workspaces.
When configuring refresh intervals, consider your data source capabilities and the performance impact on your infrastructure. Setting overly aggressive refresh rates can strain database resources and affect overall system performance. Its essential to balance the need for current data against resource utilization.
Administrators can control automatic page refresh settings at the tenant and capacity levels through the Admin Portal. They can enable or disable the feature, set minimum allowed intervals, and restrict which users can configure these settings. This governance ensures organizational resources are protected from excessive refresh activity.
After publishing to the Power BI service, the configured refresh settings remain active. Users viewing the report will experience automatic updates based on the defined intervals. The feature respects security permissions, meaning users only see data they are authorized to access during each refresh cycle.
Best practices include testing refresh configurations before deployment, monitoring performance metrics, and adjusting intervals based on actual usage patterns and business requirements.
Configure Automatic Page Refresh in Power BI
Why is Automatic Page Refresh Important?
Automatic page refresh is a critical feature for organizations that need to monitor real-time or near-real-time data. It ensures that dashboards and reports display the most current information, which is essential for scenarios like monitoring live sales data, tracking operational metrics, or observing IoT sensor readings. This feature eliminates the need for users to manually refresh reports, improving efficiency and ensuring timely decision-making.
What is Automatic Page Refresh?
Automatic page refresh is a Power BI feature that allows report pages to automatically update at specified intervals. This functionality is available in Power BI Desktop and Power BI Service, enabling reports connected to DirectQuery or streaming datasets to refresh their visuals periodically. There are two types of automatic refresh:
1. Fixed Interval: The page refreshes at a set time interval (e.g., every 5 seconds, 30 seconds, or minutes).
2. Change Detection: The page refreshes only when underlying data changes, reducing unnecessary queries and improving performance.
How Does Automatic Page Refresh Work?
To configure automatic page refresh:
1. Open your report in Power BI Desktop 2. Select the page where you want to enable auto-refresh 3. Go to the Format pane and find Page refresh settings 4. Toggle the feature On 5. Choose between Auto page refresh (fixed interval) or Change detection 6. Set the refresh interval or configure the change detection measure
Key Requirements: - The data source must use DirectQuery or be a streaming dataset - Import mode does not support automatic page refresh - Minimum refresh intervals are controlled by capacity administrators - Premium or Premium Per User capacity may be required for shorter intervals
Change Detection Setup: - Requires creating a measure that Power BI monitors for changes - Uses fewer resources than fixed interval refresh - Ideal when data changes are unpredictable
Exam Tips: Answering Questions on Configure Automatic Page Refresh
Tip 1: Remember that automatic page refresh only works with DirectQuery and streaming datasets. If a question mentions Import mode, automatic page refresh will not be applicable.
Tip 2: Understand the difference between fixed interval and change detection. Fixed interval refreshes at regular times regardless of data changes, while change detection only refreshes when data actually changes.
Tip 3: Know that capacity administrators control the minimum refresh interval. Even if you set a 1-second refresh, the admin settings may override this.
Tip 4: For questions about performance optimization, change detection is typically the better answer as it reduces query load on data sources.
Tip 5: Remember that automatic page refresh is configured at the page level, not the report level. Each page can have different refresh settings.
Tip 6: When questions mention real-time dashboards or monitoring scenarios, automatic page refresh is likely the correct feature being tested.
Tip 7: Be aware that shorter refresh intervals consume more capacity resources and may impact performance for other users sharing the same capacity.
