Create an access control rule (ACL) to prevent the Needs review field from being modified after it has been set.

## Antes de Iniciar

Role required: admin with elevated security

## Por Que e Quando Desempenhar Esta Tarefa

The newly created UI Policy makes the Needs review field
mandatory when a change request reaches the Complete
state.

The subsequent configuration of the state model ensures that a value is required in
the Needs review field before the change request can be saved
in the Complete state. To prevent the Needs review value from being changed after it has been set, create a new
access control level record (ACL) to make the field read-only.

## Procedimento

1. Open the Change Request form.
2. Open the form context menu and select ConfigureSecurity Rules.
3. Elevate your security role in the user menu that opens when you click your name in the header.  
   Only administrators with elevated security roles can add ACLs.
4. Click New.
5. Enter the following values.  
   {#t_CreateNewACL__table_wjg_xgm_b1b__entry__2}

   | Field | Value |
   |-|-|
   | Type | Record |
   | Operation | Write |
   | Name (first part) | Change Request |
   | Name (second part) | Needs review |
   | Condition | \[State\] \[is\] \[Implement\] |
   [ ]

   {#t_CreateNewACL__table_wjg_xgm_b1b}  
6. Click Submit.
