I was able to successfully use the CATALOG_VIEWS() to view modified views. In my scenario, I declared a date for the '**initlastmodificationdate**' and '**endlastmodificationdate**' parameters so that the procedure would return the elements that were modified between the declared dates, such as
CALL CATALOG_VIEWS(NULL, NULL, NULL, NULL, NULL, <start_last_modified_date>, <end_last_modified_date>, NULL, NULL, NULL, NULL)
You can refer to the [CATALOG_VIEWS](https://community.denodo.com/docs/html/browse/7.0/vdp/vql/stored_procedures/predefined_stored_procedures/catalog_views) section of the Virtual DataPort VQL Guide for more information.
Hope this helps!
