Re: Unable to connect to the data source undefined.

I'm having similar challenge, the error message i kept getting is "We couldn't connect to your DirectQuery data source or internal model. Double-check that your server and database names are correct, and that you have permission to access them". My data source is excel and local file. Please help.
