• What is the cause and solution for SAP error message CDS_UNIT_MESSAGE116 - Testing of a CDS projection view is not supported ?

  The error message CDS_UNIT_MESSAGE116 in SAP indicates that testing a Core Data Services (CDS) projection view is not supported. This typically occurs when you attempt to execute or test a CDS projection view directly in the ABAP Development Tools (ADT) or in the SAP GUI.
  Cause:
  
  Nature of CDS Projection Views: CDS projection views are designed to project or reshape data from underlying data sources (like tables or other views) and are not intended to be executed directly. They are often used as part of a larger data model or in conjunction with other CDS views.
  Testing Limitations: The testing functionality in ADT or other tools may not support the execution of projection views due to their nature of being dependent on other views or tables.
  
  Solution:
  
  Use Underlying Views or Tables: Instead of testing the projection view directly, you should test the underlying CDS views or database tables that the projection view is based on. This will allow you to validate the data and logic before it is projected.
  Create a Composite View: If you need to test the projection view, consider creating a composite view that includes the projection view and allows for testing. This composite view can be designed to include the necessary logic and data from the projection view.
  Use SQL Queries: You can also run SQL queries directly against the database tables or the underlying views to validate the data and logic.
  Check for Updates: Ensure that you are using the latest version of the SAP system and tools, as updates may include enhancements or changes to how CDS views can be tested.
  
  Related Information:
  
  CDS Views: Core Data Services (CDS) is a framework for defining semantically rich data models in SAP. It allows for the creation of views that can be consumed by various applications.
  Projection Views: These are a specific type of CDS view that allows you to select specific fields from one or more underlying views or tables, effectively reshaping the data.
  Testing in ADT: The ABAP Development Tools (ADT) provide a way to develop and test ABAP code, but there are limitations on what can be tested directly, especially with projection views.
