title: Can the user be forced to enter a non-initial value by the Table Maintenance screen in SM30?
body: <p>I'd like to force the user to chose between <code>Yes</code> and <code>No</code>, and not let him add an entry where the value is initial.</p>

  <p>This is regardless of whether I check the <code>Initial</code> checkbox in the table definition.</p>
  <p>Can this be done?</p>
  <p>Domain data type : CHAR, 1 character, no conversion routine.
  Value range: single values:
  '1' description = 'Yes'
  '2' description = 'No'</p>
