First of all, thanks for your comments, attorney28.

ozstamps answer could show us, that it is very important, in which *A FFP you spend miles. For a flyertalker who uses M&M miles MP rules are insignificant, as they are different. For M&M award tickets, I repeat my answer from the LH Board:
• You can change the dates or flight times of your free flight award for a change fee of € 50 provided award travel is available in the class you are booked. Once issued, free flight awards are nontransferable.
• Routing changes are not permitted. Unused free flight awards expire and cannot be returned or credited back to your mileage account.
If you look on RWSTAR fares for sale after 01OCT01 © kempis, it is different:

After departure:
Rerouting/reissue permitted at a charge of USD 75 per reissue.
rebooking/validation permitted at no charge except
(a) For travel originating other than Europe:
No changes permitted on remaining outbound sectors up to and including first international sector.
(b) For travel originating in Europe:
No changes permitted on remaining outbound sectors up to and including first intercontinental sector.
So basically the difference between a M&M *A Round the World Business Class award and a CRWSTAR ticket are:

• Different class of booking (=availability)
• Routing changes are not permitted on award tickets are not permitted, or RWSTAR tickets is rerouting/reissue permitted at a charge of USD 75 per reissue
• If booking class is available, change of the dates or flight times is permitted in general in both cases for free flight award the change fee is € 50.
