¿Qué causa este problema?

In the old version, the field was a key field of the table. In the new
version, the field is a non-key field.

Respuesta del sistema

The table is activated with the field as non-key field.
Foreign key relationships in which the table occurs as a check field
are modified or possibly even deleted.

¿Cómo arreglar este error?

There is a danger that data may be lost (if two records in the database
are distinguished by no other key field). If you wish to prevent this
happening, you must save this data in an additional backup table.
It may be necessary to revise foreign key relationships in which the
table is used as a check table.
