Inventory Profile Offsetting CU

Has anybody analysed Codeunit 99000854 Inventory Profile Offsetting? Description of what every function does or stands for would be very helpful.

I did some modifications in this CU but the functionality is too much to explain in a few words. Besides I think the names of the functions are pretty selfexplaining. At the technical Briefing 2002 in Denmark they gave us a powerpoint presentation of the way this CU works. Did search but couldn’t find it anymore, maybe someone else?
