Which of the following are reasons that SAP recommends developing Core Data Services view entities...

Comprehensive and Detailed Explanation From Exact Extract:

SAP recommends using CDS view entities over classic CDS DDIC-based views due to the following benefits:

Simpler and stricter syntax: CDS view entities enforce a clearer separation of concerns and reduce ambiguity, which helps ensure consistency across the stack. This makes Option C correct.

Elimination of the need for a database view: With CDS view entities, there's no dependency on a separate DDIC SQL view object, reducing redundancy and improving activation performance. This makes Option D correct.

Incorrect options:

Automated client handling (Option A) is supported in both CDS view entities and classic CDS views via annotations like @ClientHandling.

Simplified syntax check (Option B) is not a distinct feature of CDS view entities. Syntax checking is part of ABAP Development Tools regardless of the CDS flavor used.
