Message saying that a field is no longer available on a custom tab

If a custom tab has a default field, a message may, in exceptional cases, be displayed saying that the field is no longer available. This may be the case, for example, if the default field is no longer available in a new Isah release, or if the field has been moved to another default tab. You can remove the message from the custom tab and add the default field again (if it is still present on the form). If you do not have the appropriate rights to change the tab, please contact your application administrator.
