# GetItemValuation

## Overview

GetItemValuation retrieves the valuation policy assignment for an item in a company — the ItemValuation association record. Inventory value itself is carried by the general ledger and the methods' own cost state, not stored here.

## Business Rules

- Requires `itemId` and `companyId`
- Returns the ItemValuation association record (item, company, and valuation policy references)
- Returns error if no valuation record exists for the item in the company
