Question:

An admin wants to delete a standard object field in Vault. Can the standard object field be deleted?

Answer:

Fields such as these cannot be inactivated or removed, as there are code mechanisms tied to Object. However, the admin can remove the field from the page layout so that the general users do not see these fields. The admin can navigate to Admin --> Configuration --> Objects --> [Object] --> Page Layouts to remove the field.
