We have calculated diffractive dijet production in deep-inelastic scattering (DIS) at low-Q2 and next-to-leading order (NLO) of perturbative QCD, including contributions from direct and resolved photons. We study how the cross section depends on the factorization scheme and scale M{gamma} at the virtual photon vertex for the occurrence of factorization breaking. The strong M{gamma}-dependence, which is present when only the resolved cross section is suppressed, is tamed by introducing the suppression also in the initial-state NLO correction of the direct part.
