Error "Unknown data source class 'powerpivot'" Opening Published Workbook
Published: 22 Aug 2014 Last Modified Date: 26 Apr 2016
When opening a packaged workbook (.twbx) in Tableau Reader, the following error might occur:
"Unknown data source class 'powerpivot'"
Publish the workbook with a live data connection.
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.
