The interactions which preserve the structure of the gauge interaction
s of the free theory are introduced in terms of the generalized fields
method for solving the Batalin-Vilkovisky master equation. It is show
n that by virtue of this method the solution of the descent equations
resulting from the cohomological analysis is provided straight-forward
ly. The general scheme is illustrated by applying it to the spin 1 gau
ge field in three and four dimensions, to free BF theory in 2D, and to
the antisymmetric tensor field in any dimension. It is shown that it
reproduces the results obtained by cohomological techniques.
