# Configure a Primary change model

# Configure a Primary change model {#ariaid-title1}

Release version: Brazil

Configure a Primary change model so that a change using this model generates one Child change for each affected configuration item (CI).

## Before you begin

* The Major Change plugin (com.sn_major_change) must be active. For more information, see [Activate a plugin](https://www.servicenow.com/docs/access?context=t_ActivateAPlugin&version=brazil&pubname=brazil-platform-administration&ft:locale=en-US).
* A base change model to configure as the Primary change model must exist. For more information, see [Create a Change model](https://www.servicenow.com/docs/RyZRO94vLgOdLQtCmb2dXQ "Create change models to configure the states and transitions to match your organization's change processes.").

Role required: sn_change_write or itil

## Procedure

1. Navigate to AllChangeAdministrationChange Models and open the change model to configure as the Primary change model.
2. Open the state record in which Child changes are created, for example, the Assess state.  
   On the Attributes tab, add the Allow Child Change Creation attribute with Active selected. Without this attribute, Child changes are not created when the
   Primary change enters that state.
3. Select Submit.

## Result

The Primary change model is available for selection on new change requests. When a change using this model enters the configured state, the flow you configure in [Create a scaled change flow](https://www.servicenow.com/docs/BpgZIAFfdML7kKh5Mhrt8w "Create a flow to configure child change creation on the primary change model. The flow triggers when the primary change reaches the configured state.") generates one Child change for each CI in the Affected CIs related list.

## What to do next

Create a Child change model for the Child changes that this Primary change model generates. For more information, see [Configure a Child change model](https://www.servicenow.com/docs/xm96rjzOriHaiiTP94gKAw "Configure a Child change model to define the states required by the Child change requests.").
