NOTE: In the images and/or the document content below, the user information and data used represents fictitious data from the Oracle sample schema(s) or Public Documentation delivered with an Oracle database product. Any similarity to actual persons, living or dead, is purely coincidental and not intended in any manner. 

When we use a function on a view which is used in an mview, or when a function is part of the mview itself, after mview refresh staleness becomes unknown, despite compile_state remains valid 


Everything works fine if no function is used, so function may cause staleness to not know real status

Mview works fine, and refresh raises no issue, but staleness still shows same status.
