When using fields from a secondary data source, the following error might occur:

Fields cannot be used from the <secondary data source>, because there is no relationship to the primary data source. In the Data window, switch to the <secondary data source>, and click at least one link icon to blend these data sources.


Tableau Desktop


  1. In the Data pane, click on the secondary data source.
  2. Locate the linked field.
  3. Click the broken link icon to activate the relationship.


The relationship between data sources has not been activated in the view.

Additional Information

If no linking icon is visible, it may be necessary to manually edit the relationship between data sources. For more information, see Blend Your Data.
