If your audit "MI" is SQL based (on the CMN_AUDITS table) then you could just code for it there ; but if using the application audit views then probably need the data correct in the table.
Talk to CA support to see if they recognise the error, they may have an "approved" SQL fix?
Could manually create the records in the lookup audit table (unsupported) and manually "fix" CMN_AUDITS (very unsupported).
