We analyze various truncation schemes for the physical boson basis states which are required for the calculations in the boson space, in the Dyson boson mapping formalism. The available approximate schemes violate the Pauli principle and are found to be inadequate. The necessity to evolve yet a reliable and useful truncation scheme is stressed.
