VBW: Select Historical Data
Use the Select Historical Data screen in the Volumes Build Wizard (VBW) to define the historical data time range with the option of using overlap templates. If you selected the Copy Historical Data method, this screen includes a Growth Rate field.
The Wizard brings up this screen if the Build Method is Expert Average Engine, Universal Modeling Engine, or Copy Historical Data.
- Select the Start date of the historical data that you want to use.
- Select the same day of the week as the forecast scenario's first day. For example, if the target start date is a Tuesday, the historical data Start Date must also be a Tuesday.

TipIf you selected Copy Historical Data on the Select Data Build Method screen, this field is disabled. If the End date field is enabled:
- You can select a date range as short as one day, or as long as the forecast scenario for which you are building data.
