Release orders for value contract

Hi Folks,

I have question on value contract.

Customer contract is fullfilled by issuing orders against the contract. When a release order is created for the contract, the system automatically updates the released values in the contract. The release order value is calculated from the total of the open order and delivery values, plus the value that has already been billed to the value contract. System checks this value with "Outline agreement target value" in value contract and issues warning or error message depends on configuration settings in value contract item catagory.

We have business scenario where system has to check net value of value contract rather than checking "Outline agrrement target value" in value contract. Because we offer some discounts to customer in value contract thus net value of the contract differs from agreement value. So that system will issue error message when release order value exceeds net value of value contract.

Is there any customizing settings available to meet the requirement?

Awaiting for your inputs.
