    About this task

    Add the InvokeSubFlow component to get the context ID of a subflow so other Flow Designer components can check its status or obtain its output. To get the context ID of a flow, use the InvokeFlow component.

    Procedure

    1. In the Toolbox pane, navigate to ServiceNow > Flow Designer.
    2. Drag the InvokeSubFlow component to the Design surface.
    3. On the Design surface, select the Configure button Configure icon. of the InvokeSubFlow component to show the InvokeSubFlow dialog box.
    4. In the Subflow name field, enter a minimum of three characters to search and select Enter.

      A list of subflows that start with the entered characters is shown from the connected ServiceNow instance.

      Important:
      You can view and select only those subflows that have the application scope set to All application scopes. The application scope is set in the Accessible From field in your Workflow Studio instance. When the application scope of the subflow is set as This application scope only, the subflow isn’t available in the drop-down list of the Subflow name field.
    5. Select the required subflow from the search list.
    6. Verify the input fields, and select OK.
    7. Optional: Configure the properties of the InvokeSubFlow component.
      For more information, see Properties of the Flow Designer components.

      You can now connect the Context ID parameter with other Flow Designer components such as GetExecutionStatus or GetOutputs
