In this paper, we introduce GP-po-flatness property of  S -posets over a pomonoid  S , which lies strictly between principal weak po-flatness and po-torsion freeness. Furthermore, we investigate the homological classification problems of pomonoids by using this new property. Finally, we consider direct products of GP-po-flat  S -posets. As an application, characterizations of pomonoids over which direct products of nonempty families of principally weakly po-flat  S -posets are principally weakly po-flat are obtained, and some results of Khosravi, R. in a certain extent are generalized.
