Diagnosis

You tried to change the definition of the key fields of a derived type (create new key field, redefine existing key field, rename / delete inherited key field).

Subtypes are specializations of the supertype and can therefore appear at any time in the role of the supertype. For this reason, changes to key field definitions are not permitted.
