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

comment Invertible sheaves
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.

comment Properties of valuation map
@ YACP thanks. Still I could not figure out where did you use $a_{1} + a_{2} + ... + a_{n} = 0$.
