That embedded external asset appears in the lineage upstream from its Tableau content and is listed in External Assets. ![]() When an external asset (database, table, or file) is embedded in published Tableau content (workbooks, data sources, and flows), the external asset is used by the content, but is not shareable with other users. Tableau Catalog treats an external asset as ‘embedded’ if the Include external files check box is selected when a data source or workbook is published. ![]() Embedded asset appears in External Assets For example, when you select Metrics, the list of metrics depending on this workbook appears to the left of the Lineage pane.įrom the Lineage pane, you can navigate to any asset related to your initial choice, in this case the workbook, by following the links that interest you. You can select an upstream or downstream asset in the Lineage pane to see its details. When you select a field in a data source or a column in a table, the lineage is filtered to show only downstream assets that depend on the field (or column) or upstream inputs to the field (or column) as in this 'Superstore' workbook example that shows the lineage filtered for the Commission (Variable) field: (Search and filtering for fields on data source lineage pages is not available in Tableau Server.) Starting in Tableau Cloud June 2023, lineage pages for data sources include search and filtering (in the top-right of the fields list) that allow you to quickly find fields of interest or relevance. ![]() The assets above the anchor are the assets the anchor is either directly or indirectly dependent on and are called inputs or upstream assets. (In the image above, the anchor is the "Orders (superstore)"data source, and in the image below, the anchor is the "Batters" table.) All the assets below the anchor depend, either directly or indirectly, on the anchor and are called outputs or downstream assets. A lineage anchor can be a database, table, workbook, published data source, virtual connection, virtual connection table, lens, metric, or flow. Lineage shows dependencies in relationship to the lineage anchor, which is the asset selected. For more information about using parameters in flows see Create and Use Parameters in Flows (Link opens in a new window) in the Tableau Prep help. Note: Lineage data for flows won't show if the flow includes parameter values. The promotion can be disabled in your Account Settings. If you see a Lineage tab but don't have a license that includes Data Management, clicking on the Lineage tab displays a promotion for Data Management. If it's an external asset (such as a database or table) that's not in a project, navigate to it through External Assets.(This option also works for external assets that are in projects.).To see the lineage for an asset, first navigate to the asset's page. For more information about Tableau Catalog, see "About Tableau Catalog" in the Tableau Server (Link opens in a new window) or Tableau Cloud (Link opens in a new window) Help. When you have a Data Management license and Tableau Catalog enabled, you have access to lineage information for your content. The lineage feature in Tableau Catalog helps you do both these things. Knowing where your data comes from is key to trusting the data, and knowing who else uses it means you can analyze the impact of changes to data in your environment. ![]()
