  We study two functors between (partially) wrapped Fukaya categories. The
first is the Orlov functor from the Fukaya category of a stop to the Fukaya
category of the ambient sector. We give a geometric criterion for when this
functor is spherical in the sense of Anno-Logvinenko. This criterion is a
generalization of the situation where the stop comes from a Landau-Ginzburg
model.
  The second functor is the Viterbo transfer map from a Liouville domain to a
subdomain. We show that when the domain and subdomain are independently
Weinstein, this functor is a homological epimorphism, which means that it
becomes a localization after passing to module categories. This should be
compared with a result of Ganatra-Pardon-Shende, which states that the Viterbo
map is a genuine localization when the cobordism is Weinstein.
