Strict syntax and annotation checks during activation.
Simplified handling of CDS extends
Faster activation and improved performance.
Restrictions
As the CDS view entity are new and more features will be added in future. Following are the restrictions at the time of writing this blog.
Select all elements from the data source using SELECT * is not supported in CDS view entities.
DISTINCT keyword and UNION clause is not yet supported.
It is not allowed to define a client field in the SELECT list.
Co-Exists
The existing classic ABAP CDS DDIC-based (DEFINE VIEW) view will co-exist along with the new CDS view entity (DEFINE VIEW ENTITY). It is recommended to use CDS view entities instead of CDS DDIC-based view due to technical improvements.
