  Supersymmetric scenarios with R-parity conservation are becoming very
constrained due to the lack of missing energy signals, thus motivating those
scenarios with R-parity violation. In view of this, we consider a
supersymmetric model with R-parity violation and extended by an anomalous
horizontal $U(1)_H$ symmetry, where a self-consistent framework with
baryon-number violation is achieved along with a proper supression for lepton
number violating dimension-5 operators in order to keep a proton decay safe.
With the introduction of right-handed neutrinos both Dirac and Majorana masses
can be accommodated within this model. The implications for collider physics
are discussed.
