• What is the cause and solution for SAP error message CDS_UNIT_MESSAGE110 - Testing of a CDS custom entity is not supported ?

  The error message CDS_UNIT_MESSAGE110 in SAP indicates that testing of a Core Data Services (CDS) custom entity is not supported. This typically occurs when you attempt to execute or test a CDS view or entity that has not been fully implemented or is not designed to be tested in the current environment.
  Cause:
  
  Unsupported Testing: The CDS entity may be defined in a way that does not support direct testing. This can happen if the entity relies on certain features or constructs that are not compatible with the testing framework.
  Missing Annotations: The CDS view may lack necessary annotations that would allow it to be tested properly.
  Environment Limitations: The environment or system configuration may not support the testing of custom CDS entities.
  Incorrect Implementation: There may be issues in the implementation of the CDS view, such as syntax errors or logical errors that prevent it from being executed.
  
  Solution:
  
  Check Annotations: Ensure that the CDS view has the appropriate annotations. For example, check for @AbapCatalog.sqlViewName and other relevant annotations that might be required for testing.
  Review Implementation: Go through the implementation of the CDS view to ensure there are no syntax errors or logical issues. Use the ABAP Development Tools (ADT) in Eclipse to validate the syntax.
  Use Alternative Testing Methods: If direct testing is not supported, consider using alternative methods to validate the CDS view, such as:
  
  Creating a simple report or program that consumes the CDS view.
  Using transaction codes like SE11 or SE16 to view the data.
  
  
  Check System Configuration: Ensure that your SAP system is configured correctly to support CDS views. This includes checking for any necessary updates or patches.
  Consult Documentation: Refer to the official SAP documentation for any specific requirements or limitations regarding the testing of CDS views.
