I am new to Power Query and I set up a couple of transformation queries for a weekly file. The initial file ran correctly but subsequent runs return no data. I am guessing it is a source file issue. I have set up a folder for current data and named the file a generic name which I can use each time. I just move the old data out of the Current folder and place the new files there with the generic names. Even still when I open the 'connection', a blank spreadsheet displays. I am not sure what I am doing wrong.
