The Roll Forward Options are based upon the hours component on a schedule. You can modify the hours component like this:
Actual or Allocated or Budgeted (as per current schedule)
This aggregates the actual hours on the current schedule to stage category level and uses this as the basis for the actual, allocated or budgeted hours on the new schedule. The system extends the charge on the newly created schedule using the current employee category charge rates.
Actual or Allocated or Budgeted plus Uplift
This option is the same as above except that you can apply a percentage to increase or decrease the actual, allocated or budgeted hours in the current schedule. This percentage is entered into the Uplift Percentage field. If decreasing, place a minus before the percentage.
