During this course, you will learn the basic idea of Core Data Services and how SAP implemented this concept on the ABAP stack. In these three days, you will get a deep insight into the many features by which CDS Views surpass classical ABAP Dictionary views, and you will learn to leverage the full potential of CDS when defining your own views. Particular highlights will be the extended join possibilities, calculations on database level – including currency conversions –, nested views, associations and path expressions, input parameters, and the possibility to link CDS views to authorization checks. Finally, you will get an outlook on the different scenarios for CDS view consumption.

Notes
The course is held on an SAP S/4HANA system but most of its content is generic. It is applicable for any ABAP based environment, in particular SAP S/4HANA cloud and SAP BTP, ABAP Environment.
CDS ABAP does not require a specific database. You can use all its features with any database supported by AS ABAP. The only exception is the use of CDS table functions which requires an SAP HANA database.
CDS ABAP is available as of release 7.40. Some of the concepts discussed in this course require a higher release.
