  One of the important research subjects in the study of multiple zeta
functions is to clarify the linear relations and functional equations among
them. The Schur multiple zeta functions are a generalization of the multiple
zeta functions of Euler-Zagier type. Among many relations, the duality formula
and its generalization are important families for both Euler-Zagier type and
Schur type multiple zeta values. In this paper, following the method of
previous works for multiple zeta values of Euler-Zagier type, we give an
interpolation of the sums in the generalized duality formula, called Ohno
relation, for Schur multiple zeta values. Moreover, we prove that the Ohno
relation for Schur multiple zeta values is valid for complex numbers.
