Question:

Can the Owner be prevented from viewing an object record in Vault?

Answer:

Yes, an Owner can be prevented from viewing the object record if the following criteria are met:

1. The user must not have a Vault Owner Security Profile.
2. The user must be a part of a Custom Object Lifecycle Role lacking the Read permission on the object record's Lifecycle State.

Workflow Role Permissions take precedence over record ownership. Even if a user creates a record, once that record enters a state in which the user role lacks the Read permission, the user is no longer able to view the record.
