Did you know that you can extend ServiceNow user criteria by adding a custom field and then use it in your User criterias?

Here are the steps:

1. To extend user criteria, simply add a reference field from the user record to the user criteria table. The field must be of type List, and the names of the fields must match.
2. For example, to add the user’s cost center as a user criterio, you would create a new field in the user criteria table called u_cost_center and set the reference field to Cost Center.
3. Now, when you’re configuring user criteria, you’ll see the new field in form. You can use it to create more complex and powerful user criteria rules.
