Here we present a novel wave-function-based approach that preserves the entanglement information, to study both dissipation mechanisms for an arbitrary photonic Fock state process. For the scattering loss scenario, when the dissipated photon does not return to the system, we show that the effects can be incorporated by using a reduced Hamiltonian description. For the material loss scenario, nonetheless, returning nature of dissipated photons fundamentally modifies multi-photon entanglement to invalidate the reduced Hamiltonian description. Moreover, our approach reveals how scattering matrix and transport properties are modified, which is beyond the scope of DMA.
