Sales Coupon based on Sales Order values

This module extends the coupon and promotion features of Odoo so that a discount can be limited to certain sales orders. On the promotion program form, next to the existing partner condition, a new "Based on Order" field lets you build a filter on sales orders (for example, orders from a given sales team or with certain values).

When a customer tries to use a coupon or enters a promotion code, Odoo checks whether the order matches that filter. If it does not, the coupon or code is refused with the message "The order doesn't have access to this reward."

The same check is also applied when Odoo automatically looks for promotion programs that could apply to an order, so programs whose order filter does not match are simply left out. Programs meant for the next order are handled separately from those applied on the current order.

• New field "Based on Order" on promotion programs and coupon rules, edited with a sales order filter builder.
• Coupon validation and promotion code validation both respect the order filter.
• Automatic program selection for an order also respects the filter.
• Touches the coupon, promotion program and coupon rule records, and the sales order data used by the filter.
