Publishing the reports
Information about publishing your Power BI reports is available at Microsoft docs.microsoft.com/en-us/power-bi/create-reports/desktop-upload-desktop-files/
Refreshing the data
Once the report has been published you can schedule an automatic refresh of the data. Because the refresh can take a very long time, we recommend the refresh occurs overnight and the schedule corresponds to your reporting granularity. For example, if you report on monthly data, then schedule an automatic refresh once a month.
