Annotation	Simplified parquet approximation to strongly correlated electrons is generalized as to include all three important two-particle scattering channels: singlet, triplet with spin zero and spin one. The approximation is tested on the Kondo regime in a weak external magnetic field, where we found two Kondo scales for longitudinal and transversal fluctuations.
