Currently in ICM objects like publications can be created by a specific administrator, but the publication can be deleted by any other administrator.
Setup steps for the scenario:
The fact the user who created the publication is not the same user who deletes the publication is a problem for Audit and internal policies. Also the Comp Admin User ID #2 doesn't receive notification of the deletion outside of an entry in the Audit Log is another issue. The ability of another user who may not be in the same line of business is able to delete an expiring publication just because they happened to be the person who logged in at the time is proving to be a major concern.
It would be beneficial to everyone if an unsaved publication was only allowed to auto expire under the user id who originated the pub. If that isn't possible for code reasons what if the unsaved publications could be allowed to expire but there would be a notification sent to the originator and when they approved the deletion it would be recorded under their user id?
