These two fields are not used for future submission cycles. If I add a default value to FALSE or a Zero for these two Boolean type fields. Would that affect existing data? Meaning would the default value override the submitted values for any&nbsp;of the applications if they are opened&nbsp;for read only purpose and then closed?</p><p>Thanks, Sue&nbsp;</p>
