Use the $UPDFLD function in conjunction with the ON FIELD CONSTRAINT CONFLICT unit.
If $UPDFLD is invoked from an ON FCC unit following the detection of a field-level constraint conflict, it returns the name of the field in which the constraint violation occurs. At all other times, $UPDFLD returns a null string. The $UPDFLD function takes no arguments.
