Quelle est la cause de ce problème?

Certain key fields of the primary and secondary tables must be included
as key fields of the view in order to ensure an unambiguous key for the
view.
The specified field is contained in the view but was not marked as a
key field.
For fields which are linked with a join, the field of a secondary table
which is connected with the key field of the primary table can be
included in the view instead of the key field of the primary table
itself. However, this means that this field will not be marked as a key
field, causing this message.

Réponse du système

The view is activated. Errors can occur during maintenance with
transaction SM30.

Comment corriger cette erreur?

We recommend that you keep the key fields suggested by the system
in the view.
