The system calculates the effect of cannibalization when:
- A new promotion is created
- An existing promotion has been updated in the SAP SNC Web UI or via a “ProductDemandInfluencingEventNotification” XML message.
- Each time a promotion is selected to be updated during the Planning Service Manager (PSM) run.
To achieve the effect of cannibalization, at least two products impacting each other in the called cannibalization group must be related. The cannibalization factor must be assigned to the products.
If a promotion is created for a product that is in a cannibalization group, the forecasts for the other products in the group are reduced based on the cannibalization factors.
