Unable to Join Tables with Calculated Field


Published: 17 Nov 2016

Issue

You are unable to join tables at a calculated field level. 

Environment

Tableau Desktop 10.0.0

Cause

Starting with Tableau Desktop 10.2, the ability to customize joins using calculations was added to the product to resolve format mismatches between fields. For more information, see What's new in Tableau Desktop and Join Your Data.

For earlier Tableau Desktop versions, the ability to join on calculated fields was not built into Tableau Desktop. When tables or data sources are joined, a query reflecting the join is sent to the data source. Calculated Fields exist at the workbook level, not the data source level.
