For the super AKNS system, an implicit symmetry constraint between the potentials and the eigenfunctions is proposed. After introducing some new variables to explicitly express potentials, the super AKNS system is decomposed into two compatible finite-dimensional super systems (x-part and tn-part). Furthermore, we show that the obtained super systems are integrable super Hamiltonian systems in the supersymmetry manifold \mathbb {R}^{4N+2|2N+2}.
