  We revisit the integration of fields in N=1 Supergravity with the requirement
that the effective theory has a reliable two-derivative supersymmetric
description. In particular we study, in a supersymmetric manifest way, the
situation where the fields that are mapped out have masses comparable to the
Supersymmetry breaking scale and masses of the remaining fields.
  We find that as long as one stands in regions of the field configuration
space where the analytic continuation to superspace of the F-flatness
conditions be reliable equations of motion for the fields that are being mapped
out, and provided their solutions are stable regardless the dynamics of the
remaining fields, such a two-derivative description is a reliable truncation of
the full effective theory.
  The study is mainly focused to models with two chiral sectors, H and L,
described by a Kaehler invariant function with schematic dependencies of the
form G=G_H(H,\bar H)+G_L(L,\bar L), which leads to a nearly decoupled theory
that allows the previous requirements to be easily satisfied in a consistent
way. Interestingly enough for the matters of our study this kind of models
present an scenario that is as safe as the one presented in sequestered models.
  It is also possible to allow gauge symmetries as long as these appear also
factorized in hidden and visible sectors. Then, the integration of the hidden
vector superfields is compulsory and proceeds reliably through the D-flatness
condition analytically continued to superspace.
