CDS views give this subcategory its focus: Sales and Distribution data products that read SAP data through CDS views instead of physical tables. A CDS-based model covers SD objects such as sales orders, billing documents and deliveries, and its Excel template documents the relationships between those views.
Such a model can be extended with your own CDS views and Z/custom tables. For the complete SD set, including table-based variants, browse the Sales and Distribution category.
