Summary: In this paper we extend the Pietsch correspondence for ideals of compact operators and traces on them to the semifinite setting. We establish a correspondence between a shift monotone space $E(\mathbb Z)$ of sequences and a Calkin space $E(\mathcal M,\tau)$ of $\tau$-measurable operators affiliated with a semifinite von Neumann algebra $\mathcal M$ equipped with a faithful normal semifinite trace $\tau$ as well as a correspondence between shift invariant functionals on $E(\mathbb Z)$ and symmetric functionals on $E(\mathcal M,\tau)$.
