Power BI dataset refresh is a fundamental process for keeping your reports up-to-date with the most current data. Whether you’re leveraging OneDrive syncing, scheduled refreshes, manual on-demand updates, REST APIs, or Microsoft Flow (Power Automate), there are multiple ways to ensure your Power BI reports reflect the latest insights. In this guide, we explore five proven methods to refresh your Power BI datasets, how each method works, and when to use them.

1. Refresh from OneDrive or SharePoint
Power BI can automatically sync with Power BI Desktop files stored in OneDrive or SharePoint.
How It Works:
- Power BI checks the linked file roughly every hour.
- If the file has changed (i.e., saved with refreshed data), Power BI pulls the updated data model into the service.
Important: Power BI only loads the file’s current state. If you haven’t opened the PBIX file and manually refreshed the data in Power BI Desktop, no data update will occur.
2. Scheduled Refresh
Scheduled refresh is the most widely used approach in Power BI Service.
Features:
- Set refresh times in Dataset Settings.
- Supports up to 8 refreshes/day on Pro and 48/day with Premium.
- Works seamlessly with both cloud and on-prem sources (gateway required for the latter).
3. On-Demand Manual Refresh
Quick and simple—refresh the dataset manually anytime.
Use It When:
- Testing during development
- Validating new data uploads
- Immediate updates are needed outside of the schedule
4. Programmatic Refresh (API or PowerShell)
For automation fans, Power BI allows refreshes via REST API or PowerShell.
Ideal For:
- Integration with data pipelines
- Custom DevOps and CI/CD workflows
- Automated refreshes post-ETL
This method is popular in more technical environments where automation is key.
5. Microsoft Flow (Power Automate)
A newer and flexible approach, Microsoft Flow lets you refresh datasets based on triggers such as database updates, SharePoint changes, or custom events.
Use Case Example:
You have an ETL process that updates a SQL table. When a timestamped field changes, Flow detects this and kicks off a Power BI refresh.
Make sure your dataset isn’t hitting the 8-refresh limit if you’re using Power BI Pro. Use Premium for higher frequency.
Summary Table
| Method | Trigger Type | Gateway Needed | Best For |
|---|---|---|---|
| OneDrive/SharePoint | File Sync | No | Simple, gateway-free solutions |
| Scheduled Refresh | Time-based | Maybe | Regular updates on a defined schedule |
| On-Demand | Manual | Maybe | Ad-hoc data validation and testing |
| API/PowerShell | Programmatic | Maybe | DevOps, CI/CD, and automation scenarios |
| Microsoft Flow | Event-driven | Maybe | Triggering from external systems or ETL jobs |
