Question

1C-Bitrix

Hello.
I need to write the discount rules in Bitrix for the amount of the order.
Something like this:

CSaleDiscount::Add(array("LID" => $siteID, "PRICE_FROM" => 800, "PRICE_TO" => 1500, "CURRENCY" => $bRus ? "RUB" : "USD", "DISCOUNT_VALUE" => 20, "DISCOUNT_TYPE" => "P", "ACTIVE" => "Y", "SORT" => 200, "ACTIVE_FROM" => "", "ACTIVE_TO" => ""));
 CSaleDiscount::Add(array("LID" => $siteID, "PRICE_FROM" => 500, "PRICE_TO" => 800, "CURRENCY" => $bRus ? "RUB" : "USD", "DISCOUNT_VALUE" => 15, "DISCOUNT_TYPE" => "P", "ACTIVE" => "Y", "SORT" => 100, "ACTIVE_FROM" => "", "ACTIVE_TO" => ""));
 CSaleDiscount::Add(array("LID" => $siteID, "PRICE_FROM" => 1500, "PRICE_TO" => 0, "CURRENCY" => $bRus ? "RUB" : "USD", "DISCOUNT_VALUE" => 25, "DISCOUNT_TYPE" => "P", "ACTIVE" => "Y", "SORT" => 300, "ACTIVE_FROM" => "", "ACTIVE_TO" => ""));

I just can not understand where and in what file it needs to be done ????

Desktop > Marketing > Product Marketing > Cart Rules . > Rules for working with the basket
, you can make a discount on the amount of the order, and other conditions. Of course, if you have the Online Store module in the Bitrix edition.
