We investigate the maximal approximate flavor symmetry in the framework of generic minimal supersymmetric standard model. We consider the low energy effective theory of the flavor physics with all the possible operators included. Spontaneous flavor symmetry breaking leads to the approximate flavor symmetry in Yukawa sector and the supersymmetry breaking sector. Fermion mass and mixing hierachies are the results of the hierachy of the flavor symmetry breaking. It is found that in this theory it is possible to solve the flavor changing problems. Furthermore baryogenesis of the universe can be well described and neutron electric dipole moment is closely below it experimental bound by assuming approximate CP violating phase $\sim 10^{-2}$ and superpartner mass around 100 GeV.
