I walk through the new column-level data quality warnings introduced in Tableau 2022.3. I show how the warnings appear on a dashboard and in data details, then demonstrate where to set them up at the table and column level, including switching between high and standard visibility.

## Key takeaways

- Tableau 2022.3 lets you add data quality warnings at the column level, not just the data source level
- Column-level warnings require Tableau Data Management (the lineage tab) to be enabled
- You set the warning from the table view by selecting a column and using the Actions button, not from inside the workbook
- High visibility warnings pop up when you open a workbook and when you connect to the data source; standard visibility warnings show in blue and only appear under data details
- The lineage feature maps assets from the highest level (database) down to the lowest level (owner)
