For a finite-dimensional bipartite system, the relation between local projections and post-selected state dependence on the global state submatrices is given in a general setting. As a result joint state reconstruction is derived with strict local projective measurements and one-way classical communication, reducing the number of detectors in comparison to standard procedures. Generalization to multipartite systems is given, also reducing the number of detectors for multiqubits.
