Use this dialog box to copy a Level1 forecast from one master schedule set to another. You can copy from only one set at a time. When copying forecasts on Level 1, you can choose to include the forecast values from Level 0. These values usually come from the corresponding master schedule set on Level 0 as a result of a disaggregation process. All forecast information in the target set is deleted before the forecast is copied. You can also use this dialog box to combine two or more Level 1 forecasts into one, but only if you have selected several source master schedule sets. If the source set contains target set forecast values, these values are included.
