Use this dialog box to reset the Level 1 forecast of one or more master schedule sets. This means that the value of the forecast on Level 1 is set to zero. This is useful if you want to start over from the beginning with forecasts in a specific master schedule set. When resetting forecasts for Level 1, you can choose to reset the forecast values from Level 0. These forecast values usually originate from the corresponding master schedule set on Level 0 as a result of running the Level 0 disaggregation process.
