In this paper a version of the results, from the previous author's paper [8] for the space $X_D(f_1f_2)$ of the functions representable by the absolute and uniform convergent generalized Dirichlet series on a polydisc $D-D(R_1,R_2)$, is obtained. A representation of the continuous linear functional on $X_D(f_1,f_2)$ is constructed.
