Purpose
=======
Currently we are updating the coupon rewards on the fly when creating/modifying/deleting a sales order line.
To avoid multiple searches on res_partners and product to know whether the customer/product is valid on the sale coupon program, we store the applicable customers and products on the program according to the domain defined on it.
This brings 2 issues:
- The customers/products stored on the program are not updated (Was the original spec)
- The checks are numerous and maybe overkill for the given results
Specification
=============
- Don't recompute the reward lines on SO modifications. Add a button to compute the line by hand and make an automatic compute on the SO validation or on the page shop/payment.
- When recomputing the reward lines, make a search on the res_partners and products instead. Now that the action is not triggered so often we can afford to make a search.
- Don't use the fields rule_partners_domain and rule_products_domain. This should be removed in master.
- The field is_public_included is useless now. And we decided to make the coupon available for all the partners if they fit the domain on the program.
Introduces 2 new concepts:
Promotion programs:
===================
Using promotion programs allows you to propose to your customers:
- Promotional offers limited in time or a limited order number.
- Public code printed in advertisements, magasines, etc.
- Specific offers based on a customers group or a product set.
- A combination of the preceeding points.
You may choose to apply the program reward immediately on the sales order or to propose the reward for a next order. In the second case a coupon will be generated at the order confirmation for the customer to use it later.
Coupon programs:
================
Using coupon programs allows you to propose to your customers:
- Free products or discounts if some conditions on products or purchased amount are met.
- Promotional offers limited in time.
- Generate coupons for a customers group.
- Specific offers based on a customers group or a product set.
- A combination of the preceeding points.
A coupon is applied by entering a valid code if the program rules are met and if the reward is already in the order lines.
