Order Quantity Changed or Order Changed event

[pipo]

Right now I’m trying to put the discount given to individual orders in a program setting.

Automatic discount based on customer discount-level with set amounts per product

It would be nice if we could have these discounts included in the Discounts account. I’m not sure how to best approach this though. I’m thinking maybe this could work: at Payment Processed event, create an account transaction which puts the total discount amount in Discounts account, and also adds it to Sales account. I’ve tried to access the total discount value with this (but it’s not working, I get 0.00 every time): [=-1*({ORDER TAG TOTAL:D1}+{ORDER TAG TOTAL:D2}+{ORDER TAG TOTAL:D3})] …

I need to intercept any changes to the order and add/remove/change the program setting accordingly, but I cannot intercept the change when the + or - buttons are clicked.
