Yes, as tancop answered, the KOD key is encryption and obfuscation mechanism to secure the CronosPro files. And with enough schema data the correct KOD table can be inferred.

CronosPro is a proprietary format and it is assumed you are using their own software to manipulate it. As it is closed source and not really a software we dare to run on managed devices, exporting data from the Cronos format to CSV through the proprietary software becomes quite a hassle. And this is the reasoning behind the whole reverse engineering.

But of course it was a fun process and very satisfying when the normalizer actually started to work.
