  Unfolded equations of motion for N = 1, D = 4 scalar supermultiplet are
presented. We show how the superspace formulation emerges from the unfolded
formulation. To analyze supersymmetric unfolded equations we extend the
\sigma_-cohomology technics to the case with several operators \sigma_. The
role of higher \sigma_-cohomology in the derivation of constraints is
emphasized and illustrated by the example of scalar supermultiplet.
