Added in version 2021.4.1
Connect to Data
Connect to data using virtual connections for your flows. Virtual connections enable you to connect to the data without having to enter database credentials. When virtual connections have data policies applied, you can see only the data you should see. To connect, simply sign into your server and search for your virtual connections in the list.
Note: Initial SQL and Custom SQL is not supported when using virtual connections in Tableau Prep.
For more information, see Connect to Virtual Connections.
Build and Organize your Flow
With parameters you can scale your flows. Build them once, then change the parameter values to accommodate different data scenarios. Use parameters to change input data sources, values used in calculated fields or filters, or flow output locations. You can also require users to set parameter values before running flows manually or when using a schedule.
To create a parameter, specify a data type and specify the values that can be entered. Create a list of allowed values or set the allowed values to All to enable users to enter any value.
Supported parameter data types include:
- Numbers (decimal and whole)
- String (text)
Note: To run or schedule flows that include parameters on the web, the Flow Parameters settings must be enabled.
For more information, see Create and Use Parameters in Flows.
Create a tile calculation for selected fields to group rows and distribute those rows across a specified number of tiles. For example, you can create a tile calculation for product inventory. By grouping inventory, you can manage the distribution of products and allocate your inventory across your distribution network to avoid shortages in areas where products are selling out.
Using the tile feature, you can visually see how your data is being grouped and the relationship between the groups and other fields. The output is generated in a new field that determines the assignments associated with each row.
For more information, see Calculate tiles.
Keep Flow Data Fresh
Flow owners can now automate notifications for themselves, users, and groups about successful flow runs based on scheduled tasks. The notification is sent through email and includes links to the published flow on Tableau Server. As an option, you can attach Excel or CSV files that include the flow data.
For example, you can create an email notification that is based on a nightly scheduled flow run that provides sales figures to your sales team first thing in the morning.
As a flow owner, when you save the flow, you choose the type of outputas either a file, a database, or a published data source. After the flow is published, you can then add subscriptions when creating a new flow run task, or add a subscription to existing tasks.
For more information about notifications, see Notify Users of Successful Flow Runs.
To give you more visibility and ease of access to published flows, the Recents and Home pages for Tableau Online and Tableau Server now include flows. For more information about the flow, you can hover over a flow image to see the flow name, recent modifications, tags, and the name of the flow owner.
Create new flows on the web when you're making a Catalog-supported connection from the External Assets page. You must have the Data Management Add-on with Catalog enabled to use this option.
