Supported in Tableau Prep Builder version 2021.4.1 and later and in Tableau Server and Tableau Cloud version 2021.4 and later. Data Management is required to use this feature.
Flow owners can subscribe themselves, individual users, and groups to email notifications for information about scheduled tasks for successful flow runs. The email includes links to data within the Tableau environment, or you can optionally include the details of the flow run in attached Excel and CSV files.
Flow subscriptions are added to scheduled tasks for flows. You can add flow subscriptions when you create a new flow task or to an existing flow task. Email notifications are sent when the scheduled task is completed successfully.
Configure the site settings for flow subscriptions
By default, the Flow Subscriptions site setting for sending and receiving email notifications is enabled.
- The Let users send or receive emails that include flow output data option allows the flow owner to receive, and subscribe users and groups to successful flow run notifications. From the notification email, users can access the full data source or view the flow details from within Tableau.
- (Not recommended) The Attach .csv and .xlsx flow output files option lets the flow owner attach files to notification emails. The email recipients must be added to the Tableau server or site, however, the files contain the data source and can be exposed outside of the Tableau system. This option is available only for on-premise environments.
Publish the Flow
Publish the flow output as either a file, database table, or data source. Consider the following when saving the flow:
(On-premise only) When publishing you can save the output as a file or as a database table and choose to attach either a .csv or .xlsx file type to the email.
When publishing and saving the output as a published data source, the email notification provides a link to the flow in Tableau. Files cannot be attached to the email.
When choosing to save as a file output, you must use a network share and the output and input location must be included in a safe list. For more information, see Step 4: Safe list Input and Output locations.
Flow subscriptions are supported on Windows and Linux. The following restrictions apply to flow subscriptions on Linux:
- File outputs must be output to a Windows server.
- For flows that output to a file, use the UNC format for the path: \\server\path\filename. Do not use a local drive letter.
- The mounted path must be safe listed.
When attaching files to an email, the file limit is approximately 25 MB for Tableau Cloud. When using an on-premise Tableau Server, you configure the size of attachment files.
Add a flow subscription
- As the owner of the flow, select a published flow in Tableau Server or Tableau Cloud that you want to add subscriptions to for email notifications.
- You can add subscriptions to a new or existing task:
- If you are adding a subscription to a new task:
