I set up an ODBC data source connecting to a MySQL db. Previously this worked fine. I just tried creating a new report, using the same data source and now I get an error after I select the two tables I want:
Failed to save modifications to the server. OLE DB or ODBC Error 22018 MySQL ODBC 5.3 (a)
The current operation was cancelled because another operation in the transaction failed.
I have the latest version of Power BI Desktop on Windows 7.
Help?
