By scheduling your data refreshes, you can ensure your data is always up to date, making your reports and dashboards more useful and reliable.
In addition, automating data refreshes can save you time and effort. Manually refreshing data can be a tedious and time-consuming task, especially if you have multiple reports and dashboards to update. By automating the process, you can free up your time to focus on more important tasks, while also ensuring that your data is always accurate and up to date.
Understanding Power BI’s Data Refresh Options
Before you start scheduling a refresh, it’s important to understand Power BI’s data refresh options. Power BI offers several options for refreshing data, including:
- Refresh Now: This option refreshes the data immediately.
- Schedule Refresh: This option refreshes the data on a schedule that you set up.
- Refresh Manually: This option allows you to refresh the data manually when you want.
While all three options have their benefits, scheduling refreshing is the key to keep your reports and dashboard up to date automatically.
It’s important to note that the frequency of data refreshes can also be adjusted within the scheduling option. You can choose to refresh the data every hour, every day, or even every week. Additionally, you can set up alerts to notify you if a refresh fails or if there are any issues with the data source. This allows you to quickly address any problems and ensure that your reports and dashboard are always accurate and up to date.
How to Set Up a Scheduled Refresh in Power BI
Setting up a scheduled refresh in Power BI is a straightforward process. Follow these steps:
- Open the Power BI service, and select the dataset you want to refresh.
- Click on the “Settings” icon under the dataset name.
- Navigate to the “Scheduled refresh” tab.
- Select the “Keep your data up to date” checkbox.

- Save your settings.
It is important to note that the scheduled refresh feature is only available for Power BI Pro and Power BI Premium users. If you are using Power BI Desktop or Power BI Mobile, you will not be able to set up a scheduled refresh. Additionally, if you are using a dataset that is connected to an on-premises data source, you will need to configure a gateway to enable scheduled refresh.
Step-by-Step Guide to Scheduling Data Refresh in Power BI
Let’s dive into the step-by-step process of setting a scheduled data refresh:
- Open the Power BI service and click on the “Workspace” tab.
- Select the dataset that needs a refresh, and then click “More options” (three dots) next to the dataset name.
- Click on the “Settings” button under the “More options” menu.
- On the “Dataset settings” page, click on the “Scheduled refresh” tab.
- Select “Keep your data up to date” checkbox.
- Select the time of day and frequency you want the refresh to happen.
- Click on “Apply.”
It’s important to note that the scheduled refresh feature is only available for Power BI Pro and Power BI Premium users. If you’re using Power BI Desktop or Power BI Report Server, you won’t be able to schedule data refreshes. Additionally, if you’re using a data source that doesn’t support scheduled refresh, you won’t be able to use this feature. Make sure to check the list of supported data sources before attempting to schedule a refresh.
How Often Should You Schedule Data Refreshes in Power BI?
Deciding how often to schedule data refreshes depends on your business requirements and the frequency of data changes. Suppose your data is updated frequently, but your business doesn’t require real-time updates; in that case, you can schedule the refresh once a day. If your business requires real-time updates, consider using streaming datasets that refresh data incrementally rather than full data refresh.
It’s also important to consider the size of your data and the resources available for refreshing it. If your data is large and complex, refreshing it too frequently can put a strain on your system and slow down performance. In this case, it may be better to schedule refreshes less frequently or to use incremental refresh to only update the most recent data.
How to Monitor and Troubleshoot Scheduled Refreshes in Power BI
Power BI offers several tools for monitoring and troubleshooting scheduled refreshes. The “Refresh history” feature helps track refreshes for a specific dataset or data source. If there are any refresh failures, Power BI sends alerts to the owner to take necessary actions. Furthermore, the “Refresh history” feature shows recent refresh history, including the data source, start time, end time, refresh status, and any errors that occurred during the refresh.
Another useful tool for monitoring scheduled refreshes in Power BI is the “Data Gateway” feature. This feature allows you to manage and monitor the data gateway that connects your on-premises data sources to Power BI. You can view the status of the gateway, check for any errors, and troubleshoot any issues that may arise during the refresh process.
In addition to the above tools, Power BI also offers the “Refresh history” API, which allows you to programmatically access and analyze refresh history data. This API can be used to build custom monitoring and troubleshooting solutions, tailored to your specific needs and requirements.
Tips for Optimizing Data Refresh Performance in Power BI
To optimize the data refresh performance in Power BI, do the following:
- Limit the amount of data to be refreshed for your report or dashboard.
- Remove unwanted data from the dataset to reduce the data size.
- Use incremental data refresh to refresh only a part of the data that has changed.
- Use a shared data gateway to improve refresh performance for multiple data sources.
Another tip for optimizing data refresh performance in Power BI is to schedule refreshes during off-peak hours. This can help reduce the load on the server and improve the overall performance of the refresh process. Additionally, consider using Power BI Premium or Power BI Embedded, which offer enhanced performance and scalability for larger datasets and more complex reports.
Advanced Techniques for Scheduling Data Refreshes in Power BI
For advanced scheduling techniques, consider the following:
- Integrating Power Automate workflows to set up more flexible refresh schedules.
