I've booked quite complex SAS plus tickets on Expedia. Did you try to choose Airline=SAS and flexibel tickets instead of premium economy?
On the other hand, SAS does O and D availability so even if the single segments in your desired routing are available, the complete trip might not be. I've seen this several times, only booking class always available is J and up. Did you have success pricing the trip on ITA Matrix?
