Attributes doesnt cumulate for quantity discounts

[a_smith]

Hello

I am having problems taking quantity discounts to work (PS1.5.4.1).

 

My all products have attributes.

 

On CATALOG PRICE RULES i have a rule setup for -30% if 30pcs or more and -50% if 50pcs or more. No other condition grups.

 

I want it to make work of regardless of the what attributes or attributes variation has been added to the cart. The trigger is just the total quantity of whatever products /attributes in the cart.

 

It does work if a single product or attribute is greater than 30pcs or 50pcs.

But if I add to the cart 20pcs of product1/attribute1 and 20pcs of product1/attribute2 it does not work (price doesnt drop).

Also If I add to the cart 20pcs of product1/attribute1 and 30pcs of product2/attribute1 it does not either.

 

Attributes quantity doesnt cumulate in the cart.

 

I did try to change the global quantity discount setup from 'products' to 'attributes' but it does not make any change.

 

 

I saw a couple of posts about this problem on forum but no replies so far. Is this 1.5.4.1 bug that the quantity discounts doesnt work and attributes added to the cart does not cumulate?

 

Any help please?
