Quelle est la cause de ce problème?

The structure of the foreign key definition is ambiguous. When creating
the foreign key, all the key fields of the check table must be assigned
to the foreign key fields (fields of the table itself to be checked or
possibly those of a foreign table). The assignment is made using the
common domain of the pair of fields.

Réponse du système

The system automatically tries to suggest an assignment.
There are several selection possibilities for the check field in the
primary key of the check table. Therefore it is not possible to make an
assignment to the check field.

Comment corriger cette erreur?

Please define the field assignment yourself.
