We consider several scenarios of sequential measurements performed by three parties. Under the assumption on the dimension of communicated system we propose modification of the semi-definite-programming (SDP) hierarchy of Navascués-Vértesi [PRL 115 (2), 2015] that allows for approximation of the set of correlations in the considered scenarios. The variants of the scenarios that we consider include state preparation of one party and two subsequent measurements, three sequential measurements with time dependent operations and two channels followed by a measurement.
