Remove/Revoke the Violating Responsibility

To remove an existing responsibility (or Role) from a user, create a Responsibility Assignment Management request. This request will show you the existing security objects that are assigned to that user, along with the date of expiration for each responsibility. With this request, you can change the validity period of the responsibilities assigned to a specific user, change the expiration date of the user ID, assign new responsibilities to a user, revoke an existing responsibility or modify additional user attributes as available.

Note:  When an existing responsibility is revoked in a request, the responsibility still remains assigned to the user in Oracle, but the "valid to" date of the responsibility is set to "expired".
