Project description

Beta License: AGPL-3 OCA/purchase-workflow Translate me on Weblate Try me on Runbot

This module allows to set a general discount in a purchase order. This general discount is applied to each line order.

You can also set a default general discount on suppliers and configure to wich line field the discount will be applied.

Table of contents


You can set in settings another discount field to be applied. For example, if we had purchase_triple_discount, we could set the general discount in discount3 to be applied after all other discounts.

To do so:

  1. Go to Purchases > Configuration > Settings and Purchase Discount Field

  2. Select the discount you’d wish to use. purchase_triple_discount fields will appear when the module is installed.

There’s a method at called _get_purchase_discount_fields that can be used to extend more line discount fields. For example, if we had the field discount4, we could extend it like this:

def _get_purchase_discount_fields(self):
    discount_fields = super()._get_purchase_discount_fields()
    discount_fields += [('discount4', _('Discount 4'))]
    return discount_fields


To set a partner default general discount you need to:

  1. Go to a partner and set the general discount in Sales & Purchases tab.

To set a general discount in a purchase order you need to:

  1. Create a purchase order.

  2. Either select a partner with a purchase general discount defined or set one in the summary section of the order.

  3. This discount will be applied to every line.
