Direct Activity Allocation KB21N

Hi,

We have a scenario wherein we capture power cost (consumed & purchased ) on one cost center. We book actual quantity through KB21N. Then in KBK6 we put actual rate based on cost center cost and actual quantity booked on this cost center. Now when we do MFN1, production orders are not getting revaluated. It shows blank data. Can anyone please advice if we are missing any steps ? This solution we require is urgent.

Regards,
