¿Qué causa este problema?

Every secondary table of a lock object must be connected to a base
table above it in the hierarchy by a join condition. This join
condition must be implemented by a foreign key. This foreign key must
have the secondary table as foreign key table and the base table above
it in the hierarchy as check table. One of the join conditions of the
lock object is implemented via an inconsistent foreign key relationship.

Respuesta del sistema

The action is cancelled.

¿Cómo arreglar este error?

Ensure that the join condition is implemented via a valid foreign key
relationship.
