You’re interested in the implementation patterns of CDS views in SAP’s digital core? Then the keyword here is VDM.
SAP S/4HANA’s virtual data model (VDM) uses ABAP CDS views to offer a simplified, easy-to-understand and harmonized data model on top of the suite tables (but avoiding their cryptical technical names). It is enriched with business semantics and enables an easy consumption of the business data.
ABAP CDS allows the definition of semantically rich data models providing all metadata that are necessary to build analytical or transactional apps or even remote APIs.
VDM represents the cornerstone of the programming model in SAP S/4HANA.
The main characteristics of VDM views are:
- Easily understandable & semantically rich
- Reusable & stable
- Executed on SAP HANA
Customers and partners can develop on top of the released VDM views.
In the session S4H220 – Implementation Patterns for CDS Views in SAP S/4HANA– at SAP TechEd 2017, some insights were provided by SAP’s experts on how the virtual data model is structured and how to implement the different types of core data services views required for building analytical apps, transactional apps and remote APIs.
