There is incorrect open order value with UKM_RVKRED88 / UKM_RVKRED77

Hi,do you ever meet this problem in S4 1511?

I recreate my open value following the steps below:

1.delete open value with transaction UKM_COMMITMENTS;

2.recereate my openvalue with report UKM_RVKRED77.

As a result, some orders with partial delivery have full open order value and open delivery value. So there are double open value.
