How can data be refreshed in Power BI?

The ability to refresh data in Power BI through manual or scheduled options allows users to maintain the currency and accuracy of their reports and dashboards. Manual refresh enables users to update the data whenever they need it by simply clicking a button within the Power BI interface. This is particularly useful when users want immediate updates based on the latest data available.

On the other hand, scheduled refresh lets organizations automate the process of keeping their reports up-to-date without requiring user intervention each time. Users can set specific intervals for the dataset to refresh, such as daily or weekly, ensuring that the reports are always reflecting the latest data. This dual capability of refreshing data both manually and through scheduling provides significant flexibility and convenience, making it easier to maintain data integrity in business intelligence reports.

The other methods mentioned, such as manual entry, scripted automation, or deleting and republishing, either restrict the refreshing process or introduce unnecessary complexity. These approaches do not offer the same convenience and efficiency as the manual and scheduled refresh options.
