  We summarise possible explanations of the HERA large-Q^2 data, in the
framework of R-parity violating supersymmetry. Experimental limits indicate
that the most likely production channels are e^+ d --> scharm_L, e^+ d --> stop
and e^+ s --> stop. We study the regions of the parameter space that lead to
consistent branching ratios, with and without the unification condition for
gaugino masses. Cancellations in the coupling of the lightest neutralino to
scharm_L, result in a balance between R-parity violating and R-parity
conserving decay modes. Such cancellations are not present in the coupling of
the neutralino with other particles and an interesting case is sneutrino_L,
which could be produced at LEP2 via an L_1L_{2,3}{E}_1^c operator. On the other
hand, the stop branching ratios depend mainly on the mass of the lightest
chargino and tend to be dominated by either the R-conserving or the R-violating
mode.
