  This paper is aimed at providing a very first, more "global", systematic
point of view with respect to possible conflict generation in CA-EN-like causal
structures. For simplicity, only the outermost level of graphs is taken into
account. Localization of the "conflict area", diagnostic preferences, and bases
for systematic conflict generation are considered. A notion of {\em Potential
Conflict Structure} ({\em PCS}) constituting a basic tool for identification of
possible conflicts is proposed and its use is discussed.
