Advance pricing

hi,

I am using jd 9.1. I am using advance pricing for sales, for all items and all customers. My business scenario is as follows:

No discount for first 100 items sold in sales order. then discount of fixed 10dollars for every 100 quantity.

100 qty ----  No discount

200  qty --- 10 dollars

300 qty ---- 20 dollars

400 qty ---- 30 dollars

For this I have already done the initial setups. Now I want to set, adjustment revision in P4072. I have set From level equal to 100 and Factor value equal to (-10), so that discount will start after 100 items. my question is how to set, if discount  is 10 dollars every 100 items. Please Help me by guiding the required set up.
