In this paper we show that if the Nemytskii operator maps the $$(\phi ,2,\alpha )$$ -bounded variation space into itself and satisfies some Lipschitz condition, then there are two functions g and h belonging to the $$(\phi ,2,\alpha )$$ -bounded variation space such that $$f(t,y)=g(t)y+h(t)$$ for all $$t\in [a,b]$$ , $$y\in {\mathbb {R}}$$ .
