When opening a workbook, which is based on a file-based data source (for example, a live or extract-based Excel connection) and uses a formula-based Top-N filter, with both an LOD and a math operator (example "SUM([Sales])/sum({sum([Sales])})"), in Tableau Desktop 10.4 and later, then publishing to a 10.3 or earlier Tableau Server, the following unexpected error messages display consistently: 
"Reconnect to data source


  • Tableau Desktop 10.4 and later
  • Tableau Server 10.3 and earlier
