With the goal of understanding base volume and then accurately forecasting your base volume, POS data is critical. Rate your data here  Pre-event analysis requires an accurate incremental forecast of merchandising conditions: TPRs, features, displays and ads. Post-event analysis takes total actual volume and subtracts the base volume which equals incremental volume. An automatic upload of this data and calculations that are digitalized allows you quick visibility and the fastest reaction time to negotiate course corrections to your plan. 

View the history and make the course corrections needed when you are editing or creating, all in the same place rather than in a reporting module. This will save you a tremendous amount of time, eliminate errors and end user frustration. With Vistex, you can do this within a single application portal instead of an external application. The analysis is within the promotion entry screen.
