Thank you Georges. I was thinking to construct $f$ such that $f$ is regular on $U.$

comment Invertible sheaves
Thank you all. @ Matt here $n_{p}$ is a coefficient of $P$ at $D,$ which is a integer.

Thank you all. It seems $L_{D}(U)$ is an $\mathbb O_{X}(U)$-module.

comment Existence of GCD in an integral domain
@ Arturo Magidin, I have small comment on the last paragraph of your answer. I think $D$ is a GCD domain if and only if group of divisibility is a lattice ordered group. This is the theorem by Krull, Kaplansky and Jaffard.
