sale_margin_delivered

Purpose

Compute delivered margins on sale orders using actual delivered quantities and costs so profitability reflects what was shipped and returned.

Features

sale.order.line: Computes delivered margin, delivered margin percent, and delivered unit cost from stock valuation layers so profit reflects outgoing deliveries and refund returns, falling back to purchase cost for non-storable products.
sale.order.line: Shows delivered cost, delivered margin percent, and delivered margin columns on sale order lines when margin visibility is enabled in the sales order form.
sale.report: Adds an aggregated delivered margin measure to the sales analysis report with proper currency conversion for reporting comparisons.
