• Ensure that your data source supports scheduled refresh.

3. Using Gateway for On-Premises Data

• If your data resides on-premises, you may need to install and configure the Power BI Gateway.
• The Gateway facilitates secure data transfer between on-premises data sources and Power BI Service.
• Schedule refreshes can then be configured for datasets connected to on-premises data.
