SO Creation: Correct Contract type?

Dear All,

I want to create Sales Orders against a contract which will:

1. Not allow the Material specified in the contract to exceed target value (like checks implemented in Material Contract)

2. Not allow the Value of the Contract to exceed target value (like checks implemented in Value Contract)

So basically the requirement is to have the user create SO wrt a contract that has features of both Material and Value Contracts.

Is there any Contract type in which we can specify both target Value and Quanitiy ?

Thanks and Regards,

Ashwin
