• What is the cause and solution for SAP error message CDS_UNIT_MESSAGE014 - The CDS under test '&1' must not be provided in the dependency list ?

  The SAP error message CDS_UNIT_MESSAGE014 indicates that there is an issue with the dependency list of a Core Data Services (CDS) view or entity that you are trying to test. Specifically, the error states that the CDS view you are testing should not be included in its own dependency list. This is a common issue when defining CDS views, especially when they reference themselves or create circular dependencies.
  Cause:
  
  Self-Reference: The CDS view you are testing is directly or indirectly referencing itself in its dependency list.
  Circular Dependency: There may be a circular reference where two or more CDS views reference each other, leading to a situation where one of them is included in its own dependency list.
  Incorrect Annotations: The annotations or definitions in the CDS view might be incorrectly set up, leading to unintended dependencies.
  
  Solution:
  
  
  Review the CDS Definition: Check the definition of the CDS view you are testing. Ensure that it does not reference itself directly in the define statement or indirectly through other views.
  
  
  Remove Self-Reference: If the CDS view is included in its own dependency list, remove it. You should only include other views or tables that are necessary for the view's logic.
  
  
  Check Dependencies: If your CDS view depends on other views, ensure that those views do not create a circular dependency. You may need to refactor your views to eliminate such dependencies.
  
  
  Use Annotations Correctly: Ensure that you are using the correct annotations and that they are not causing unintended dependencies. For example, check the @AbapCatalog.sqlViewName and other relevant annotations.
  
  
  Testing: After making the necessary changes, re-run the test for the CDS view to ensure that the error is resolved.

  ABAP Development Tools: Use tools like ABAP Development Tools (ADT) in Eclipse to visualize dependencies and help identify issues in your CDS definitions.
  Documentation: Refer to the official SAP documentation on CDS views for best practices and guidelines on defining views and managing dependencies.
  
  By following these steps, you should be able to resolve the error message CDS_UNIT_MESSAGE014 and successfully test your CDS view.
