With this feature, you can forecast the demand for lifecycle products (for example, one-time-purchase products such as fashion, or consumer electronics such as mobile phones). Lifecycle products pose particular challenges to demand modeling and forecasting in that they exhibit strong lifecycle effects on the one hand, but have sparse historical sales data on the other hand.

A new model definition supporting lifecycle products has been added to the Assign Demand Model Definitions
Customizing activity under . For more information, see the Customizing activity documentation (transaction SPRO).
Preprocessing has been enhanced to fill gaps in the historical sales data with zeros. This “zero sales inferencing” improves the modeling results.
Note
If you want to trace the changes during preprocessing, you can set this up in Customizing under
. For more information, see the Customizing activity documentation.The Calculate Hierarchical Priors
service of the Schedule Model and Forecast
function has been enhanced. You can now also generate hierarchical priors based on relationships between generic products and their variants. As before, you can find the results of the Calculate Hierarchical Priors
service in the /DMF/UMD_PRI
table.
Activation: No special activation is needed. Simply provide the data for your generic products and variants as you do with other master data.
Example:
Product Type | Table /DMF/PROD | Example |
---|---|---|
Generic product |
| Short sleeve shirt |
First variant of the generic product |
| Medium red short sleeve shirt |
Second variant of the generic product |
| Medium blue short sleeve shirt |
Customizing: When configuring hierarchical priors, you can prioritize and weight the generic-product-variant relationships as you can with product hierarchies and location hierarchies. For this purpose, two weight parameters have been added to the /DMF/HPR_CTRL
control table for hierarchical priors:
Parameter | Default | Description |
---|---|---|
| 1 | Weight of your generic product and variant hierarchy against your product hierarchy |
| 1 | Weight of your default product hierarchy |
You can set these weights in the existing Configure Hierarchical Priors
Customizing activity under . For more information, see the Customizing activity documentation.
