Users can publish Power BI reports and dashboards in Power BI Server or Power BI Service. However, the Power BI reports and dashboards won’t refresh unless users apply a refresh, either based on a refresh schedule or on-demand. Scheduled Refreshes are the scheduling tasks set for data extract refresh so that they get refreshed automatically while publishing a report and dashboard with data extract. This also removes the burden of republishing the reports and dashboards every time the concerned data gets updated.
