7. Choose the refresh frequency (e.g., hourly, daily, weekly) and enter the start time.
8. Click “OK” to save the settings.
Real-Time Data Refresh
Real-time data refresh is an advanced feature that allows you to update your reports with the latest data as it becomes available. This is particularly useful for scenarios where data is constantly changing, such as financial reports or stock market analysis. Here’s how to enable real-time data refresh:
1. Open your Power BI Desktop application.
2. Go to the “Home” tab in the ribbon.
3. Click on “Options and Settings” > “Options”.
4. In the “Options” dialog box, go to the “Data Source Settings” tab.
5. Under “Real-time Data Refresh”, click on “New”.
6. Select the dataset you want to enable real-time refresh for.
7. Choose the refresh frequency (e.g., every few seconds) and enter the start time.
8. Click “OK” to save the settings.
Conclusion
Refreshing data in Power BI is essential for maintaining accurate and up-to-date reports. By understanding the different methods available, such as manual refresh, scheduled refresh, and real-time data refresh, you can ensure that your Power BI reports always reflect the latest data. With this knowledge, you’ll be able to leverage the full potential of Power BI for your data analysis and visualization needs.
