Error "undefined binding" When Creating a Cross-Database Join with Three Tables

Published: 18 Jul 2017

When creating a cross-database join with three (or more) tables using a web data connector (e.g. the ServiceNow connector), an error may occur:

Undefined binding
Unable to create extract


  • Tableau Desktop 10.3.0, 10.3.4, 10.4.0
  • Web data connector
  • Windows


Try one of the following workarounds:
  1. Set up the cross-database join between just two tables on the Data Source tab. 
  2. Click on the tab for Sheet 1 to create the initial extract. 
  3. After the extract has been created, go back to the Data Source tab to add the third table.
