The authors study an initial boundary value problem (IVBP) for a scalar conservation law. It is shown that the theory of shift differentiability can be extended to this case. Then a certain functional on the solutions of IVBP is considered and a necessary condition for its stationary points are deduced by means of the obtained first order shift expansion.
