In ServiceNow, when a new field is added to an existing table, it is not automatically included in any existing List views. List views are predefined configurations that determine which fields are displayed when viewing records in a list format. To display the new field in a List view, you must manually modify the List layout to include the field.

Steps to Add a New Field to a List View:

Navigate to the List Layout Configuration:

Go to the table's list view.

Right-click on the header row (where the column titles are displayed).

Select "Configure" and then "List Layout."

Add the New Field:

In the List Layout configuration, you'll see two columns: "Available" and "Selected."

Locate your new field in the "Available" column.

Use the arrow buttons to move the new field to the "Selected" column, placing it in the desired order.

Save the Configuration:

Click "Save" or "OK" to apply the changes.

The new field will now appear in the List view as configured.
