Pricing with quantity dependency and variant configuration ?

Hi all,

For some options (characteristic value) of my configuration I have to specify a quantity (let's say for example 1, 2, 3 or 4). In this case I create a copy of the characteristic just for quantity.

Characteristic: 'A' (char, single value)

Characteristic value 'a1', 'a2'

Characteristic: 'A_QTY'

Characteristic value: (num, additional value)

I have one variant condition for each option in vk30 ('vc-a1' and 'vc-a2'), I maintain the price of the option with quantity 1 in vk12 ('vc-a1' = 100 and 'vc-a2' = 200).

using a procedure and the object characteristic SDCOM_VKOND I can link the variant condition and the option which don't have a quantity dependency. But what about the option with a quantity such as 'a1' and 'a2' ?

I tried to use $set_pricing_factor but without success

I used the following coding:

$SET_PRICING_FACTOR ($SELF, SDCOM_VKOND, 'vc-a1', A_QTY) IF SPECIFIED A

Any idea ?

Thank you for your help
