Delete all data and connection from PBI desktop model
I would like to know the proper way to delete all data and connection to a power BI desktop file.
I deleted all the tables and PBI tell me that I have no data source connected to the file, fine. But when I want to make a direct connection to an online PBI model, I have an error message saying that my file contains data from an other source so I cannot do the connection the right way.
Do you have any idea why and how I can properly delete all data source / data of my file ?
