I created a report using Power BI Desktop with dataset from a local csv file. I have published that report to Power BI Service (Free version). It works fine.
But now I want to source the report's dataset from a csv file in my Office 365 E3 Sharepoint site. I have successfully created a new dataset in Power BI Service from the Sharepoint csv.
Now I want to swap my published report's dataset for this new Sharepoint source dataset.
Can I swap them in Power BI Service, or do I have redo the report recreating the dataset source using the Sharepoint csv file, and then republish the updated report to Power BI Service?
Is there some programmatic way of doing this? Eg with Power BI API can I change report datasource?
