Snapshots provide a easy way to save the current value of the Forecast data for week over week or month over month comparison. To take snapshots first create a forecast report. Once the report is defined, you can take Forecast Snapshots on a daily, weekly or monthly basis as desired. Each snapshot is labelled uniquely with a time stamp and the system provides you the ability to view the snapshot data and compare data with another snapshot (created from the same forecast report) at a different time. It also provides you to see the delta (difference) between two snapshots. This capability can be used to see for example how the Forecast changes for example from week to week or month over month.
