Part Number B10286-02
(end_date in date default sysdate);
Purges all users and roles in the WF_LOCAL_ROLES and WF_LOCAL_USER_ROLES tables whose expiration date is less than or equal to the specified end date and that are not referenced in any notification.
Note that although users and roles whose expiration date has passed do not appear in the seeded WF_USERS, WF_ROLES, and WF_USER_ROLES views, they are not removed from the Workflow local tables until you purge them using Directory(). You should periodically purge expired users and roles in order to improve performance.
