    Familiarize yourself with the other Workflow Studio components. Dynamic inputs are created with actions and subflows:
    1. In the ServiceNow AI Platform, you will create a new data definition for the dynamic input fields you want to add to an activity.
    2. In Workflow Studio, you will create a data gathering action.
    3. Still in Workflow Studio, you will create a subflow or another action with a dynamic input to consume the first action. This subflow or new action creates a JSON schema that represents the field(s) you want to add to an activity.
    4. In the ServiceNow AI Platform, you will create an activity definition using the subflow or action with the dynamic input.

    Once your activity definition is created, Playbooks authors can add and configure activities with the dynamic inputs.

    このタスクについて

    A dynamic input is an input that changes based on another input. In Workflow Studio Playbooks, you can present multiple dynamic inputs based on another input.

    Example

    When a user requests catalog items, you can dynamically present a list of catalog variables based on the selected catalog item.
    1. The first input required is for the Catalog Item field.
      Input for a Catalog Item
    2. A user selects iPad mini in the Catalog item field.
      A user selecting iPad mini as the Catalog item
    3. Two (2) additional fields for color and storage options appear in response to the user selecting an iPad mini as the Catalog Item.
      Two additional fields for color and storage options appear

    手順

    1. Navigate to All > Workflow Studio and select Actions.
    2. Create an action to add an input.
      The input appears under the Script step > Input Variables section. The JSON under the Script section should include the new input.
    3. In the Outputs section, click Edit Outputs to make sure that the value of the Name field is output, and that JSON is the selected in the Type drop-down field.
    4. Create a subflow with the new input.
    5. Navigate to All > Process Automation Administration > Activity Definitions.
    6. Open or create the activity definition to add the new input to.
    7. Under the Automation Plan tab, make sure the action or flow you created with the new input is the underlying Flow or Action, and that the new input appears in the Variables section.
    8. Change the visibility of the new input from Show as additional property to Always show.
    9. Save your changes.
      Once your activity definition is created, Playbooks authors can add and configure activities with the dynamic inputs.
