Order Settlement Rule

Hi Friends,

I have setup a PM Orders which collect all the maintenance and running cost (internal service). I have assigned settlement Profile "Internal Order" with settlement rule "Mandatory for release".

Now when I click settlement rule button in work order, there are two distribution rules PER and FUL both 100% and to same cost centre will diaplay.

But requirement is to flow only 100% for Full not require PER, There is any SPRO settings so i can change ? please suggest me on the same.

Regards,
