Working with Top n Product Lists 
To be able to generate top n product proposals, you must first manually create a top n product list.
In Customizing, you have made all the necessary settings in Customizing for top n product lists. In particular, if your top n product list is to contain products determined from SAP BI, you will need to carry out the activity .
Create top n list
When creating a top n list, you specify whether the list is active or not. Only lists with status Active can be used in the application (CRM Web Channel, for example).
Create item
You can add items to an existing top n list. An item combines products, segments, and validity periods.
You can set the exclude indicator either for the entire item or only for a particular validity period. This defines, for example, that none of the products belonging to this item should be proposed.
You can assign individual products manually or products determined from SAP BI. For products from SAP BI, you must select a rule and a BI report to have the products determined.
You also have the option of setting the exclude indicator here, that is, excluding the products defined for this particular item.
