C, or, in other words, computing backwards in Membrane Computing is an extremely
hard task. The current approximations are based in heavy hand-made calculus by consid-
ering the specific features of the given configuration. In this paper we present a general
method for characterizing all the configurations C ' such that produce a given configura-
tion C in transition P systems without cooperation and without dissolution.
