    Tableau Prep - Change Data Source

    Rodney Englart

      Hi.  I need to change the data sources for prep (Excel files), either moving from development test data to production files, or in production to update files with weekly data refreshes. When I select a data source, right click and select edit, a file picker dialog opens.  When I select a new file, the following error appears.  In the example below I'm attempting to point Prep to the 27-May file replacing the 15-May file.  Any suggestions on how I solve this problem?

       

       

       

      Cheers
