Document Management - Enhancem. to log changes to Classification Character.

Has anybody come across the need of tracking changes to classification characteristics in the standard DIR change log?

Standard functionality does not add change records to the DIR log when classification characteristics are changed. Since we operate in an regulated environment, we need to have a complete audit trail for any changes made to the DIR.

Does anybody have an idea how to best go about this? Is there a BADI that would be a good starting point? Any ideas are welcome.

Thanks in advance,

Friedrich
