Embedded analytics with your own CDS views

What are CDS views and what is the Virtual Data Model (VDM)?

The Virtual Data Model (VDM) in SAP S/4HANA and SAP S/4HANA Cloud is a consistent representation of CDS views (Core Data Services) and follows defined modeling rules. It forms the basis for data access in SAP S/4HANA, for example for analytical applications of embedded analytics.

CDS views are based on SQL expressions and annotations to define data structures, relationships and filters, thus enabling efficient database queries.

The VDM provides an abstracted view of the data in SAP S/4HANA and SAP S/4HANA Cloud, which enables a uniform and simplified data access layer for various applications.

What are the advantages of CDS views?

Simplified data modeling

CDS views can be used to model data in a logical and structured way by providing an abstract view of complex data structures. This greatly simplifies the development and maintenance of data models in SAP S/4HANA.

Improved performance

By using CDS views, developers can execute very complex queries directly on the HANA database (so-called code push down) and thus improve query performance. CDS views enable the development of aggregates, filters and other performance improvements directly at database level.

Reusability

The modular structure of CDS views in folder structures allows them to be reused, which in turn speeds up development and promotes consistency in data modeling. Developers can modify or even extend existing standard CDS views to efficiently meet new development requirements.

Cross-system integration

CDS views can be integrated into various systems, such as Fiori, SAC for visualizing data or as a data source in the SAP Datasphere. This enables comprehensive analysis of data across a wide range of SAP systems.

      CDS views as a data source

      In SAP S/4HANA, SAP continues to deliver the familiar standard extractors for the Business Warehouse. CDS technology opens up new ways of extracting data more efficiently while using the same data model as in the analytical Fiori apps.

      • Efficient data provision for BW / Datasphere reporting. Faster provision for reporting means that reporting cycles can be shortened and relevant information can be better analyzed.
      • Standardization of the technology and data source used for operational reporting, simplifying maintenance and reducing complexity.
      • Previous extractors had to be initialized, which led to a booking stop in the system. With CDS technology, extractors no longer need to be initialized. This means that operations in S/4HANA are guaranteed throughout.

      FAQs

      There are two different types of CDS views in the SAP world:

      • ABAP CDS views
      • HANA CDS views

      In SAP S/4HANA Embedded Analytics, the data models are modeled with ABAP CDS views.

      The difference between the two views lies mainly in the technology used and the area of application

      • ABAP CDS views can be used for embedded analytics.
      • HANA CDS views are developed natively on the HANA database.

      CDS views are defined in SQL. Annotation gives them additional functionality, e.g. for the hierarchical representation of data.

      With the help of annotations, CDS views can be enriched with additional information or metadata.
