In this talk, I will review the unifying relation for amplitudes first. Then I will show how to reproduce this from an off-shell version. In addition, this relation also holds for the off-shell Berends-Giele currents in some cases. I will also show how to generate this to the AdS (dS) amplitudes (wavefunction coefficient). Next, I will review the sewing procedure of the BG currents and then reproduce the unifying relation for 1-loop integrands. Finally, I will show how to generalize this to the (A)dS case.
