Order level discount should be applied on extended price not on the List price

Dear Team,

We are having the following scnerio.

Order level Modifier has to apply on the Extended price.

EX: Item a list price is 1000

System is applying 25% on the line level discount now my extended price is 750.

In Order level modifier i have given the Qualifier as Order Amount is between 1000-9999999

After applying the line level modifier my order amount is 750 but my Order level modifier alos applying. We want to apply the Header level modifier only, if the order amount(Extended Price) is exceeds 1000

Kindly suggest.

Regards,

Nagendra
