I walk through a new enhancement to Explain Data in Tableau 2020.3, where you can now choose the fields used for Explain Data directly from the data source pane before running any analysis. I show how to right-click the data source and select Choose Fields for Explain Data to tick or untick fields like Profit.

## Key takeaways

- In Tableau 2020.3 you can configure Explain Data fields from the data source pane before doing any analysis
- Right-click the data source on the left, then select Choose Fields for Explain Data to open the field-selection interface
- The interface is identical to the one previously found inside Explain Data, letting you tick or untick fields such as Profit
- Unticked fields are excluded from the Explain Data analysis when you later run it on a mark
