¿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 a
foreign key relationship with the check field specified. For this
foreign key relationship, however, no foreign key fields can be found.

Respuesta del sistema

The action is cancelled.

¿Cómo arreglar este error?

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