Sale Order Lot Selection Price

This module links the lot/serial number selected on a sales order line to the price used on that line.

• On a sales order line, once a lot or serial number is picked, the unit price is recalculated from the price stored on that lot, not from the product's standard sales price.
• The recalculation happens automatically when the lot changes, so the line price stays consistent with the selected lot.
• The lot price is taken from the lot's own sales price (list price) and, for cost-related calculations, from the lot's cost price.
• It works together with the modules that add lot selection on sales order lines and lot price fields on stock lots.

It affects the sales order line (sale.order.line) and the product pricing logic (product.product). No new menus, screens, buttons or reports are added; the change is visible directly in the unit price field of the sales order line when a lot is selected.
