Which option allows the combination of various data layers in SAP S/4HANA for efficient reporting?

The option that allows the combination of various data layers in SAP S/4HANA for efficient reporting is CDS Views.

CDS (Core Data Services) Views are a powerful feature within SAP S/4HANA that enables the definition of semantically rich data models at the database level. They provide a way to create data models that can easily integrate data from various sources and layers within the SAP system. This integration includes the ability to combine data from different applications and transactional data in real-time, which is crucial for generating reports and analytics efficiently.

CDS Views leverage the capabilities of the underlying HANA database, such as its in-memory processing and advanced SQL capabilities, making it ideal for complex reporting requirements. They also support annotations for defining metadata, which enhances the usability of the data for reporting tools and business applications.

Moreover, using CDS Views supports a layered architecture, promoting better data governance and reusability. This way, users can focus on business logic rather than data access methods, simplifying the process of retrieving data for reporting purposes.

While other options, such as Data Warehousing, Data Lakes, and SQL Views, serve specific roles in the data management landscape, they do not inherently provide the same level of integration and efficiency for reporting that CDS
