When refreshing an extract of an Anaplan data source that contains a physical join, after changing the data type of the fields that are used for the join, the following error may occur:

Unable to complete action
Internal Error - An unexpected error occurred and the operation could not be completed.
Error Code: 6EA18A9E
Unable to create extract


  • Tableau Desktop 2020.4 and newer
  • Tableau Server 2020.4 and newer
  • Anaplan


Use one of the following workarounds:

Option 1

Use a relationship instead of the physical join.

Option 2

  1. Duplicate one of the affected fields: Right-click (control-click on a Mac) the field in the Data pane, and select Duplicate.
  2. Change the data type of the duplicated field to the desired data type for the purpose of building views.
