The manual refresh method of PowerBI is basically the same as that of Excel. We realize manual refresh of data by refreshing the data source. Of course, PowerBI and Excel have two operations: single data source refresh and global data source refresh. If we want to refresh a single data source, we can refresh the data in the data field. The specific operation steps are as shown in the figure.
Of course, in actual application scenarios, there is rarely a single data source. In this case, we need to manually refresh the data in PowerBI to achieve global refresh of the data content. The global refresh function is located on the PowerBI homepage as shown in the refresh operation button.
