Issue

When connected to a Published Data Source (Tableau Server/Tableau Online) in Tableau Prep, the calculated field editor might show an "Unknown Field Name" error when a dimension or measure is referenced.

Environment

Tableau Prep Builder 2019.4.1 and 2019.3.2

Resolution

As a possible, use one of the following options:

Option 1

Click OK/Save to exit the calculated field editor. The behavior is a false negative limited to the calculated field user interface. The field itself should still be created and work as expected

Option 2

Revert to an earlier version of Tableau Prep Builder such as 2019.3.1.
