I had another FPL rejected by Austrian authorities. Was from Salzburg westwards outbound via their VFR points. Looked ok to me, but I got this message:

FPL NOT ACCEPTED.
ADVISE BORDER POINTS AND CORRECT ROUTING.

I notice that SD doesn't put border crossing points in, but I've always been used to doing this when filing manual FPL's. So what's the story .. is SD supposed to produce a usable FPL when crossing country boundaries, or is it just a template which always has to be manually modified ? Obviously one can always put a waypoint on the boundary somewhere but it always to appear as coordinates, which seems to be disliked by several authorities.

(weirdly after calling the Vienna ATS, the lady who answered said the FPL looked ok, and accepted it without me modifiying it).
