New Canvas Workflow

To add a JST in the New Canvas :

1. In the Search bar (top of the Task panel), start typing Transformation to locate the transformation task.

2. Drag the Transformation task to the canvas.

3. Connect the Transformation task to the Start and End tasks. Transformation tasks can be connected to any two tasks that require you to transform data due to different data formatting requirements​.

4. Double-click the Transformation task to view available settings. Choose the Transformation needed and then edit the incoming variables.

5. Select the appropriate options (see table below) you would like to use prior to running your transformation.

   Option (New Canvas)	Description
   Mask Input Variable Values	This option is available on all tasks. It encrypts incoming variables and displays them as asterisks in Jobs (formerly Job Manager).
   Mask Output Variable Values	This option is available on all tasks. It encrypts outgoing variables and displays them as asterisks in Jobs (formerly Job Manager).
   Extract Output	This option only applies if you have a single outgoing schema. It removes the wrapper object from the output and returns only the value of that property.
   Validate Incoming	Validates your input. Checks if the input is the correct type and compatible with any keywords set in that incoming schema i.e. enum or const.
   Revert To Default Value	Enables use of a default keyword. Default values from the incoming schemas will be used whenever a key/incoming data value is not provided. If an outgoing schema has a default value, an incoming schema is assigned to it. If the incoming schema does not have a default defined, then the default for the outgoing schema will be used. If an outgoing schema has a default value defined, and nothing is assigned to it, then the default values will be in the transformation output.

6. Close out of the task and it will automatically Save the task choices.

7. Save the Workflow and then click the Start button (top-right) to run the transformation.
