Ok I see, the restriction only applies to the target variable, but not
the whole data set.
As I have currently to deal with a list of series, I simply apply the
restrict command to each series separately, and construct a temporary
series which consists only of units fulfilling the restriction.
Thank you, Allin.

smpl pnobs(target) >= x --restrict
where "target" is the series you want to use for the minimum
valid observations test.
