  In this work we construct the crossing symmetry equations for mixed
correlators of two long and two BPS operators in 4D $\mathcal{N}=1$ SCFTs. The
analysis presented here illustrates how our general group theoretic approach to
long superblocks and tensor structures of superconformal algebras can be
applied to give explicit ready-to-use expressions. In the case at hand, we
obtain a system of four crossing symmetry equations for the relevant OPE
coefficients. One of these four equations coincides with the equation found and
analysed by Li, Meltzer and Stergiou by restricting to the superprimary
component of the long multiplets. The other three equations are new and they
provide powerful additional constraints on the same OPE data.
