“Error! Cyclic reference detected.” - This error message implies that cyclic reference is detected in database foreign keys structure. Cyclically ordered relations can become an entry point for such error occurring.
Example: Foreign keys defined for particular tables can be arranged cyclically. This fact provokes the error appearing in case you attempt to convert such a database with converter. Here you can see that all foreign key dependences participated in cyclic chain are marked red.
To eliminate this error it will be enough to delete one foreign key reference to avoid getting the error about cycle. Thus the cyclic chain of links can be broken. In other words you should unselect it and make it unavailable for conversion.
