Rebate Agreement , Final settlement credit memo request is rejected

Hi Friends,

When we go for final settlement of a rebate agreement we create a final settlement request. After doing so the agreement status becomes "C" and once we create the credit memo for this request the status of agreement moves to "D".

My Problem is there are few agreement wherein the final settlement request is craeted but rejected and these agreement are stuck in "C" status.

I want to push these agreements into "D" status. I am not able to find some way to do that . Need your help ?
