Set the Updatable Field Property

You can set fields of a layout to be read-only or updatable. For example, consider a custom layout created for the Ticket object, named Closed Ticket, which only applies when the status of the ticket is closed. Here, Ticket is a custom object.

The following steps define how to set the Ticket Name, Priority, and Status fields of the custom layout as read-only and to set the Close Comments field to updatable.

Note: By default, the fields are updatable

Define Fields as Read-Only

To change the status of the Ticket Name, Priority, and Status fields to Read-Only:

1. Navigate to the Details Page Layouts section of the Ticket object.

2. Select Closed Ticket Layout.

   The Details Layout page appears.

3. Click the Ticket Name field.

   The Edit UI Properties page appears.

4. In the Layout Properties section, select No from the drop-down list of the Updatable property.

5. Click Save and Close.

6. Repeat for Priority and Status fields.

7. Click Done on the Details Layout page.

   The Ticket Name, Priority, and Status fields are now read-only for the edited layout and the Close Comments field is updatable by default.
