Change a non-required custom field to required

You can change a Custom field that is not required, so that it is required on all future transactions. To do this, check the Required check box in the custom field widget for a record. New transactions will require the field to have a value in order to save, or in any other way proceed to the next step in the records life cycle.

Changes you make to custom fields do not appear on custom pages until your next login. Similarly, users who are logged in when you make changes to custom fields do not see those changes until they log out and log in again.
