The analytical app Demand Waterfall Analysis
helps you improve your forecast accuracy and the stability of your demand and supply plan through an effective analysis of historical forecast data. The app enables a waterfall analysis based on snapshots of forecasts taken at different points in time, which you can display in tables and charts to visualize the evolution of your forecast over time. The analysis helps you identify the types of input that contribute to higher forecast accuracy.
Analyze snapshots of forecast data as follows:
View snapshots in personalized tables and charts.
Note
The periodicity of snapshots is either weekly or monthly, depending on the periodicity type for waterfall analysis defined for the replication model used.
You can specify the periodicity type in either of the following transactions:

(Recommended when using SAP enhancement package 2 for SAP Supply Chain Management 7.0, Support Package 7, or higher)
Replication Model Maintenance (Maintenance View)
You can access the transactions on the SAP Easy Access

Display the deviation of past forecast data from actual sales data for the same period
Define a critical threshold for forecast deviation and highlight critical values in the table in red
Compare several snapshots for a specific period and visualize them in a waterfall chart
Analyze forecast accuracy as follows:
View the forecast accuracy key performance indicator calculated for the analysis period on the main screen
The system calculates forecast accuracy by subtracting the value of the forecast error
(mean absolute percentage error, MAPE) key figure from 100%. For more information, see SAP Note 1792742.
Define and display trends of forecast accuracy
Note
Trends of forecast accuracy are shown in the form of symbols beside each value in the table view of the main screen. See the following table for the meaning of each symbol:
Symbol | Meaning |
---|---|
Upward arrow | Increasing forecast accuracy compared to the previous snapshot |
Downward arrow | Decreasing forecast accuracy |
Minus sign | No trend |
Diamond symbol | “Not applicable” |
Filter the data for your analysis in the following ways:
Based on characteristics or navigational attributes
By defining an analysis period
