  General sufficient conditions are given for absolute continuity and
convergence in variation of the distributions of the unctionals on a
probability space, generated by a Poisson point measure. The phase space of the
Poisson point measure is supposed to be of the form (0,\infty)\times U, and its
intensity measure to be equal dt\Pi(du). We introduce the family of time
stretching transformations of the configurations of the point measure. The
sufficient conditions for absolute continuity and convergence in variation are
given in the terms of the time stretching transformations and the relative
differential operators. These conditions are applied to solutions of SDE's
driven by Poisson point measures, including an SDE's with non-constant jump
rate.
