推荐答案

除非您具有支持增量刷新的查询源，否则Power BI将不会存储数据.

Power BI will not store data, unless you have a query source that will support incremental refresh.

最好使用Azure Function，Azure Logic Apps或Power Automate之类的工具来获取数据并将其另存为文件，然后从该文件夹导入数据.另一种选择是将数据移动到数据库表中以保留历史记录.

It would be best to use a tool like Azure Function, Azure Logic Apps or Power Automate to get the data and save it as file to a folder then import the data from the folder. Other option would be to move the data to a database table to preserve the history.
