Error "reference to unknown table" When Opening Workbook After Upgrade
Published: 13 Sep 2018 Last Modified Date: 20 May 2019
When opening a packaged workbook (.twbx) after upgrading Tableau Desktop, the following error might occur:
"An error occurred while communicating with the data source. reference to unknown table"
If it is possible to keep the workbook open after the error, check action filters on the dashboard(s) in the workbook. If the error appears on action filter target worksheets, remove the action filter(s) and re-create them.
An action filter may have corrupted the workbook.
