Metadata Manager makes most Tableau object types available for data lineage. However, there are some data lineage restrictions on Tableau objects.
The following Tableau objects have data lineage restrictions:
Dashboards
Metadata Manager does not display data lineage for dashboards. However, you can run data lineage analysis on the worksheets that are included in the dashboard.
Data sources
Data sources in Tableau can be either live data sources or extracts. A live data source represents a connection to a physical data source such as a relational database. An extract is a snapshot of a data source that is saved to a .tde file.
When you view a data lineage diagram that includes a live data source, Metadata Manager displays the physical data source in the data lineage diagram. For example, if you run data lineage analysis on a Tableau live data source that is based on an Oracle table, Metadata Manager displays the Oracle table in the data lineage diagram. Metadata Manager displays a link between the Oracle table and the Tableau live data source.
When you view a data lineage diagram that includes an extract, Metadata Manager displays the extract as the source for data lineage. Metadata Manager does not display a link between the physical data source and the extract. Metadata Manager does not display the link because it cannot determine which physical data source an extract is based on.
