How to Edit Blend Relationship in Tableau?

To edit the blend relationship between data sources in Tableau, you can follow these steps:

  • Open the Workbook: Launch Tableau Desktop and open the workbook containing the data sources you want to blend.
  • Navigate to the Data Source Tab: In Tableau, locate the data source tab at the bottom of the screen. Click on it to access the Data Source tab.
  • Edit Blend Relationships: In the Data Source tab, you will see a list of the data sources used in your workbook. To edit the blend relationship, find the connection that you want to modify and right-click on it. From the context menu, select "Edit Relationships."
  • Adjust Relationship Properties: The Edit Relationships dialog box will appear, displaying the existing blend relationship between the selected data source and others. You can make the necessary modifications to the relationship properties here.
    • To add a new relationship, click on the "+" button or select "Add" if available. Specify the fields from each data source that should be linked.
    • To modify an existing relationship, select it from the list and click on the "Edit" button. Adjust the field mappings or other properties as needed.
    • To remove a relationship, select it from the list and click on the "-" button or choose "Remove" if available.
  • Validate and Apply Changes: After making the desired changes to the blend relationships, click on the "OK" button to save and apply the modifications.
  • Update Worksheets: Once the blend relationships are edited, Tableau will update the data blending within your worksheets. Review and verify that the data is blended correctly by examining the visualizations and data connections.

Remember, blending data from multiple sources can have performance implications, especially if the data volume is large or the blend relationships are complex. It's essential to optimize your blend relationships for efficiency and ensure that the results align with your data analysis requirements.

Note: The ability to blend data sources and edit relationships may vary based on the version of Tableau you are using.
