Heavy flavor probes are sensitive to the properties of the quark gluon plasma(QGP) produced in relativistic heavy-ion collisions. A huge amount of efforthas been devoted to studying different aspects of the heavy-ion collisionsusing heavy flavor particles. In this work, we study the dynamics of heavyquark transport in the QGP medium using the rapidity dependence of heavy flavorobservables. We calculate the nuclear modification of $\text{B}$ and $\text{D}$meson spectra as well as spectra of leptons from heavy flavor decays in therapidity range $[-4.0,4.0]$. We use an implementation of the improved Langevinequation with gluon radiation on top of a (3+1)-dimensional relativisticviscous hydrodynamical background for several collision setups. We find thatthe rapidity dependence of the heavy quark modification is determined by theinterplay between the smaller size of the medium, which affects the path lengthof the heavy quarks, and the softer heavy quark initial production spectrum. Wecompare our results with available experimental data and present predictionsfor open heavy flavor meson $R_\text{AA}$ at finite rapidity.
