Special Price logic

[Ross.Nospario]

*Specific Price

 

 

I need to change the way Special Prices decide which discount to use, but not using the shop/country/currency logic.

 

I've attached a screenshot with an example of the discounts I need to include.

 

What the logic needs to do is simply see which of the discounts is the highest and select that. At the moment it feels the priority is:

 

Customer -> Group -> Generic

 

I need it to ignore that priority and just look at the Impact, selecting the best reduction.

 

Is there any easy way to change this, or which model should I be looking at to change?

I changed this

 

                ORDER BY `id_product_attribute` DESC, `from_quantity` DESC, `id_specific_price_rule` ASC, `score` DESC'); 

 

to

                ORDER BY `id_product_attribute` DESC, `from_quantity` DESC, `id_specific_price_rule` ASC, `reduction` DESC');

Line 234
in classes/SpecificPrice.php

 

It appears to have done it. Will be thoroughly testing now.
