Discount by quantities of product category
This module will add a button inside the sale order and will compute the discount not by line but by quantities of the same product category, in the same sale order. e.g.: You've defined 10% discount for Category A for 100 PCE min in the List price.
You try to sell 50 Pieces of Product A and 50 Pieces of Product B (defined on Category A). The OnChange in the line will compute the price of the product as usual. Then you click on the new button. The unit price will be updated as you've sold 50+50 = 100 pieces of the same category! => you will have 10% discount on both lines !

auto_awesome What this module does
AI-generated from the code · Odoo 12.0Adds a 'Compute global discount' button on quotations and sales orders that recalculates line prices using the total quantity of each product category in the order, so volume discounts apply across products of the same category.
This module changes how volume discounts from pricelists are applied on a sales order. Normally each line is priced on its own quantity. With this module, a new button 'Compute global discount' appears on the quotation/sales order form, next to the 'Send by Email' button, and is available while the order is in Draft or Sent state.
When clicked, the module adds up the ordered quantities of all lines that belong to the same product category (ignoring cancelled orders), then looks up the pricelist price for that combined quantity. The resulting unit price is written back on each line of that category, so all lines benefit from the volume discount.
- It groups quantities by product category, not by individual product.
- It follows pricelist rules, including pricelists based on another pricelist.
- It only updates prices when the matching pricelist rule is category-specific; otherwise the normal line price is kept.
- It only runs on draft or sent orders, so confirmed orders are not changed.
It touches sale.order and sale.order.line and uses the standard product pricelist logic. No automatic computation happens on its own; the user must press the button.
