A generalization of the non-local coherent potential approximation (NL-CPA) for the treatment of short range ordering (SRO) effects in complex unit cell solids with different forms of disorder is proposed. The method is discussed with respect to fully first-principles Korringa, Kohn and Rostoker multiple scattering theory, and a tight-binding model hamiltonian. Examples from the context of applications to metallic alloys, diluted magnetic semiconductors, and half-metals in the presence of antisite disorder are discussed.
