    Is it possible to force a field to be write once and not editable after a value is populated?


    Resolution

    The Purpose of the documentation is to show a possible way to incorporate a write once attribute to a field.  For this example the field to be modified is the Assignment’s Assignee field.  Ultimately, the process should allow end users to populate a value initially to the field, but not allow any changes to that value.
