Atlan requires the Site Administrator Explorer role in Tableau to extract data source fields and calculated fields. It is not possible to fetch data source fields and calculated fields with the Viewer role in the current version of the Tableau Metadata API. We use this data to generate granular column-level lineage across data sources and SQL assets.
To extract lineage for assets in Tableau, the user must have the Site Administrator Explorer role. Learn more about how to set up Tableau with this guide.
