The Delta app doesn't trace your baggs once in KL territory. As others wrote, fill out a Property Irregularity Report (PIR) at CPH. You will get a reference number from AF/KL and a enveloppe with all the info. With that number you can trace your luggage either by calling them or checking on the web.
