In this paper, under the most elementary conditions on stochastic differential equations (SDEs in short) and the most elementary conditions on backward stochastic differential equations (BSDEs in short) introduced by Peng, in the space of processes, a limit theorem for solutions to BSDEs with its terminal data being solutions of the SDEs is obtained, based on some recent results of Jiang in the space of random variables in [Jiang, L., 2005a.
