Set the Tableau Prep Flow Authoring count to 0 first, then disable Gateway.


This is a known issue that is under investigation and being addressed by the Tableau development team.

Additional Information

Currently, Tableau Prep Flow Authoring uses the Gateway as a component process along with Data Engine and Tableau Prep Flow Service.
If the Tableau Prep Flow Authoring count is set to 1 or more, the gateway process cannot be removed for that node.
