We derive the general scaling equation to the second order for a model, describing any point scatterer, with degenerate energy levels, embedded into a gas of itinerant electrons. We show how the obtained previously scaling equations for spin-anisotropic Kondo model follow from it. We introduce the notion of the anisotropic Coqblin?Schrieffer model. We apply the general equation to derive scaling equation for that model and integrate analytically the important particular case of that equation.
