Let \(\mathbb {L}\) be a Dedekind complete unital f-algebra. We prove the Riesz-Kantorovich formulas for order bounded \(\mathbb {L}\)-module homomorphisms from a directed partially ordered \(\mathbb {L}\)-module with the Riesz Decomposition Property into a Dedekind complete \(\mathbb {L}\)-vector lattice satisfying an additional mild condition.
