008D99B0 FORM IS...USING cannot be applied to DMU domains. The USING clause has been removed from domain "!AD". Explanation: The clause USING added to the FORM IS clause in domain definitions (to specify an exchange record to be used while moving data to and from a form), can be used only with domains defined in CDO, because only the CDO protocols allow for this clause. User Action: Put the domain definition in a CDO dictionary or remove the USING clause.
