Group condition - scale base

[Former Member]

dear experts,

i have made a group condition with group condition routine -> Material pricing group ... and it is working well

but i have a strange requirement that the scale is based on the percentage of the material group quantity from the total order quantity

for example : if the quantity of certain material = 15% of total order quantity - > the discount is -2 USD per one

if the quantity of certain material = 20% of total order quantity - > the discount is -5 USD per one

please advice

You can use a scale basis formula (this is a setting on the condition type.)
