If you want to return different fields than what you input, you'll need to include a get_output_schema function in your script that defines the output and data types. Note: Date and DateTime must always be returned as a valid string. String in ISO_DATE_TIME format “YYYY-MM-DDT:HH:mm:ss” with optional zone offset. String in ISO_DATE format “YYYY-MM-DD” with optional zone offset. The following data types are supported: Data type in Tableau Prep Builder 'Supplies Group Encoded' : le.fit_transform(input), 'Competitor Type Encoded' : le.fit_transform(input), 'Opportunity Result Encoded' : le.fit_transform(input), 'Route To Market Encoded' : le.fit_transform(input), 'Region Encoded' : le.fit_transform(input), 'Supplies Subgroup Encoded' : le.fit_transform(input), You will also need to return the results in a pandas (pd.DataFrame) using supported data types.įor example to add encoding to a set of fields in a flow, you could write the following script: def encode(input): This will call your data from Tableau Prep Builder. When you create your script, include a function that specifies a pandas (pd.DataFrame) as an argument of the function. To disable the TabPy connection enter the following command For example -tabpy-connect-timeout-ms 900000.
Version 2020.4.1 and later: You can create, edit, and run flows that include script steps in Tableau Server.Version 2019.3 and later: You can run published flows that include script steps in Tableau Server.If you plan to publish, create, edit, and run flows that include script steps in Tableau Server, you will need to configure a connection between your TabPy server and Tableau Server. You must use a pandas data frame in your scripts to integrate with Tableau Prep Builder.Ĭonfigure the Tableau Python (TabPy) server for Tableau Server Tableau Prep Builder uses TabPy to pass data from your flow through TabPy as the input, applies your script, then returns the results back to the flow. Follow the installation and configuration instructions for installing TabPy.

Running flows with script steps in Tableau Online, isn't currently supported. You can run flows that include script steps in Tableau Server as long as you have configured a connection to your TabPy server. When you add a script step to your flow and specify the configuration details, file, and function that you want to use, data is securely passed to the TabPy server, the expressions in the script are applied, and the results are returned as a table that you can clean or output as needed. Then you can use Python scripts to apply supported functions to data from your flow using a pandas dataframe. To include Python scripts in your flow, you need to configure a connection between Tableau and a TabPy server.
By sending Python commands to an external service through Tableau Prep Builder, you can easily extend your data preparation options by performing actions like adding row numbers, ranking fields, filling down fields and performing other cleaning operations that you might otherwise do using calculated fields.
