Error "Unknown data source class 'powerpivot'" Opening Published Workbook


Published: 22 Aug 2014
Last Modified Date: 26 Apr 2016

Issue

When opening a packaged workbook (.twbx) in Tableau Reader, the following error might occur:
 
"Unknown data source class 'powerpivot'"

Environment

  • Tableau Reader
  • Microsoft PowerPivot

Resolution

Publish the workbook with a live data connection.

Cause

Tableau Reader can open only packaged workbooks that are connected to extracts or workbooks that contain live connections to file-based data sources, such as Excel or text files. Because extracts cannot be created from Microsoft PowerPivot data sources, Tableau Reader cannot open packaged workbooks that contain connections to PowerPivot.
