Internal Order Settlement

Hi

I got an investment order and values posted to it. However this month there were few incorrect entries that got posted and we managed to reverse those.

Now we need to settle this  investment order to an asset. We need to settle only 20% so the settlement rule was set to 20% PER. When we did the test settlement run we noticed that the settlement is not taking 20% of the net value. It takes 20% of the gross value as credit, and 20% of each reversal line.

Is there a way to settle only 20% of the net value to the asset

Please assist

Thanks
