In the paper we give a general approach  to a problem  of difference methods
for a class of impulsive partial differential or
functional differential equations. Initial and initial - boundary
value problems for first order partial equations
and  parabolic problems are considered. A theorem on the error estimate for functional difference equations
with impulses is given. The proofs of the convergence of difference schemes are based on this general
idea.  Nonlinear estimates of the Perron type for given functions
with respect to functional variables are considered.
Numerical examples are presented.
