Is lineage available for Tableau custom SQL data sources?

Yes, Atlan can parse custom SQL queries in Tableau to generate lineage between the data source and tables. Lineage is available for tables from all SQL sources. However, column-level lineage is currently not supported.

Can users who do not have access to a dashboard still see the preview?

Users can only see asset previews if the following conditions are met:

  • They have the necessary permissions in both Tableau and Atlan.
  • They are logged into Atlan and Tableau on the same browser.

Therefore, if a user lacks the permission to view a dashboard in Tableau, they will not be able to view the dashboard preview in Atlan. Even if they do have the necessary permissions, they will need to be logged into Tableau on the same browser as their Atlan instance for asset previews to work.

Why can I not see previews for my Tableau assets?

  • Your Tableau assets will be updated with previews during the next run of your Tableau workflow. If you have run the workflow and still do not see the previews, we suggest you rerun the workflow. Once you've rerun the workflow, the previews should be visible to all eligible users.
  • If you're using Tableau Server with clickjack protection enabled and your Tableau instance URL is of a different origin than the Atlan instance URL, the asset previews will not load due to a same-origin error from the browser. You will need to disable clickjack protection to allow the Tableau asset previews to load.
