SD Contract with Material Determination - error V1 118 - Material Not liste

We have a contract that was created in Jan 2011. We have a material on the contract that has now has a sub through material determination. Since the original item has item linked to it out process is the add the new item to the bottom of the contract. when we do this we are getting Error 118 - Material is not listed therefore not allowed.

I debugged it and it looks like if the vdatu (req del date) is populated that is used otherwise the create date of the contract is used. The contract was created in Jan however the material determination is only valid from 4/25 going forward.

Has anyone experience this issue? Is there a way around this?

I have searched the forums and haven't found anything like this.

thank you for you help.
