Purchase Order Qty change no recompute

This module changes how Odoo reacts when you edit a purchase order line. Normally, changing the quantity or the unit of measure on a line can trigger Odoo to recompute other fields such as the line description, the planned date, the unit price and the discount.

With this module installed, those other fields are no longer recalculated just because the quantity or unit of measure changed. The link to the product is still used so that the first calculation happens correctly when you pick a product.

• Applies to purchase order lines (purchase.order.line).
• Affects the fields name, date_planned, price_unit and discount.
• Removes product_qty and product_uom from the triggers that cause those fields to be recomputed.
• Keeps product_id as a trigger so the initial values are still filled in.

There are no new menus, buttons, reports or settings. The change is automatic and only affects the internal recalculation behaviour of purchase order lines. It is useful when you want to adjust quantities without losing manually entered descriptions, prices or dates.
