[otrs] OTRS in french

Hi, I use OTRS in french and I translated the web interface by adding some expressions or words translations in the fr.pm file delivered in the installation package. But there are some terms that seem not possible to translate in the fr.pm file So, the actions displayed in the tickets history as "newticket" or "UpdateCustomer" or the days displayed in pdf-edition are not translated. Could someone tell me where should be placed the translations for this ? Regards Claude
