  We investigate the existence of vortex configurations in two gauged-$CP(2)$
models extended via the inclusion of magnetic impurities. In particular, we
consider both the Maxwell-$CP(2)$ and the Chern-Simons-$CP(2)$ enlarged
scenarios, separately. We choose a $CP(2)$-field configuration with a null
topological charge not only in the simplest (free) case, but also when coupled
to an Abelian gauge field. The implementation of the
Bogomol'nyi-Prasad-Sommerfield (BPS) formalism shows that the effective models
for such a configuration possess a self-dual structure which looks like those
inherent to the gauged sigma models. Therefore, when the $CP(2)$ field is
coupled to the Maxwell term, the corresponding total energy possesses both a
well-defined Bogomol'nyi bound and a quantized magnetic flux. Further, when the
$CP(2)$ scenario is gauged with the Chern-Simons action, the total electric
charge is verified to be proportional to the quantized magnetic flux. In
addition, the analysis verifies that the magnetic impurity contributes to the
BPS potentials and appears in both the models' BPS equations. Next, we
introduce a Gaussian type impurity and solve the self-dual equations via a
finite-difference scheme. The resulting solutions present a nonmonotonic
behavior that flips both the magnetic and electric fields. Finally, we discuss
the topologically trivial solutions in the limit for which the impurity becomes
a Dirac $\delta $-function.
