Can quantity based price can be maintained in Scheduling Agreement?

Hi,

I would like to create a Scheduling Agreement in which, based on quantity price shall be changed.

For Example :

For initial 200 pcs price is Rs.20/- per piece.

From 201 price need to be Rs.17.50/- per piece.

I maintained scaled in Info record but found same price is being picked when Goods receipt is made,price is not found to be changed after crossing 200 pcs.

Thanks in Advance.
