SAP PM : Maintenance Order Confirmation(Work)

Hi,

      In Maintenance Task List We define  work

                                   Work involved in the activity  =  Activity duration * Number of person/ Capacities

     In maintenance order operations  also we can define   work (Created through Maintenance Plan)

                                   Work involved in the activity  =  Activity duration * Number of person/ Capacities

Now when We do confirmation where/how can we define the ActualNo of person / Capacities  to calculate Actual work.

as we have actual duration.

Thanks
