Set a Data Quality Warning
Data quality warnings are a feature of Tableau Catalog. Starting in 2019.3, Tableau Catalog is available in the Data Management Add-on to Tableau Online and Tableau Server. When Tableau Catalog is enabled in your environment, you can set data quality warnings. For more information about Tableau Catalog, see "About Tableau Catalog" in the Tableau Server or Tableau Online Help.
You can set a warning message on a data asset so that users of that data asset are aware of particular issues. For example, you might want to let users know that the data hasn't been refreshed in two weeks or that a data source has been deprecated. You can set one data quality warning per data asset, such as a data source, database, flow, or table.
Who can see the data quality warning
When you set a warning, the warning is visible to users of the asset and any assets downstream from it. For example, a warning set on a table is visible to users looking at a dashboard with an upstream dependency on that table.
Who can set a data quality warning
To set a data quality warning, you must
- be a server or site administrator, or
- have the Save capability for the asset.
How to set a data quality warning
There are several types of data quality warnings you can set on a data asset:
