Abstract: Let $ v$ and $ u$ be, respectively $ n$-superharmonic and $ n$-harmonic functions on the product of $ n$ harmonic spaces. We prove that the iterated fine limits of $ \frac{v}{u}$ exist and are independent of the order, for $ \lambda $ almost every minimal boundary element where $ \lambda $ represents the function $ u$. As an application we prove an important property concerning the reduced function of a positive $ n$-harmonic function.
