Hello
it's been a while since I have the following warning that I would like to solve. Do you have any idea what the message means and how to solve it?

System:     - aggregating on 'CHIAVE'(Pk_AnnoMese_Competenza) with Cardinal(36), for Object:  in Doc: 1a103ccb-f59c-4e0c-9ece-8f211537a6c

thank you
