Cross-selling refers to a product according to the same rules as up-selling . Cross-selling delivers products that were purchased together with the reference product. The recommendation engine is necessary for cross-selling . If you have not licensed the recommendation engine (from FactFinder or PredictiveIntent), the selection option is not available.
The same general conditions apply to the settings as for up-selling: You determine the number of suggested products and can have them displayed in a personalized manner if necessary .
