# Create subflow

# Create subflow for Design and Assign function {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Create a subflow in the Workflow Studio. You can use this subflow to configure an activity in the playbook for the Design and Assign function.

## Before you begin

Role required: admin, sn_ni_core.inventory_admin

## About this task

You create a subflow by defining the input data that the subflow uses and the output data it generates. Then you link the subflow to a request definition. You can use this request definition to configure an activity to
automate the design and assign function using a playbook. The subflows associated with request definitions are triggered by the TNI Design Assign process flow after you submit them.

## Procedure

1. Navigate to AllProcess AutomationFlow Designer.
2. Select New and then select Subflow from the option list.
3. Fill in the following fields:  
   {#create-subflow-design-assign-playbook__table_kt4_t1l_mcb__entry__2}

   | Field | Description |
   |-|-|
   | Subflow name | Name of the subflow. |
   | Description | Description of the subflow. |
   | Application | Application scope to create the subflow in. You can select Network Inventory Advanced. |
   [ ]

   {#create-subflow-design-assign-playbook__table_kt4_t1l_mcb}
4. Create the subflow input and assign an appropriate value to the subflow output according to your requirement.  
   To learn more, see [Create a subflow in Workflow Studio](https://www.servicenow.com/docs/access?context=create-subflow&version=australia&pubname=australia-build-workflows&ft:locale=en-US).  
   Note:  
   The subflows are triggered by the TNI Design Assign process flow on submission, and the following inputs are required.
   * Ignore validation error
   * Change task
   {#create-subflow-design-assign-playbook__ul_o5n_2wd_zdc}

## What to do next

* Test the subflow, and publish it when it's ready to be added to the record producer.
* Create a request definition and associate the subflow. To learn more, see [Create a request definition for Design and Assign function](https://servicenow-prod.fluidtopics.net/cqim8AoAYN9G~CqWEfyS7A "Create a request definition and use it to configure the Design and Assign playbook. You can use this request definition to configure an activity for the Design and Assign playbook.").
