Per SAS earning chart O is Go and not something higher.
Whether it's Go or Go light, per this flyertalk post can't be decided based on the booking class alone:
SAS Go Light will be available in the same booking classes as SAS Go, but will be offered to a lower fare than SAS Go and exclude checked baggage allowance in the ticket.
It will be possible to buy checked baggage, as well as other additional services, from time of reservation until departure. For passengers who want to travel with checked baggage, it will be more favorable to buy a SAS Go ticket with baggage included.
The concept is set to be rolled out on 8 September [2015], initially as a test on routes between Scandinavia and six European countries – Finland, France, Greece, the Republic of Ireland, the Netherlands and Spain.
Notably Germany is missing. I would conclude that you will be booked into SAS Go as Go Light doesn't exist on this route at this time.
