sorry I don't understand well. As I said user is well qualified for both promotions and this is well reflected on basket but not in plan. I suppose this is due because one of my promotion is negative. So maybe you can't calculate well DISCOUNTED_PRICE for this reason.
Take a look to attached screenshot. The normal price plan in this example is 899 and my negative promotion increase the price for get 1043 (this is correct and is what I need). Now the additional promotion should apply 20% discount on this global increased amount. So instead to display 719.20 (which is the discounted amount of 899) it should display 834.40 (which is the discounted amount of 1043).
If you look on basket screenshot you can see all correct price and amount...proof all promotion are well applied. The green one is my negative promotion and the yellow one the normal.
