• What is the cause and solution for SAP error message CDS_UNIT_MESSAGE109 - Testing of a CDS abstract entity is not supported ?

  The error message CDS_UNIT_MESSAGE109 in SAP indicates that you are trying to test a Core Data Services (CDS) abstract entity, which is not supported. Abstract entities in CDS are typically used as a base for other entities and cannot be instantiated or tested directly.
  Cause:
  
  Abstract Entity: The CDS view you are trying to test is defined as an abstract entity. Abstract entities are meant to be extended or used as a base for other entities, and they do not have a concrete implementation that can be executed or tested directly.
  Testing Context: The testing framework in SAP expects a concrete entity that can be executed, and since abstract entities do not provide this, the error is raised.
  
  Solution:
  
  
  Use Concrete Entities: Instead of testing the abstract entity directly, you should create a concrete entity that extends the abstract entity. You can then test the concrete entity.
  
  Example: If you have an abstract entity Z_Abstract_Entity, create a concrete entity Z_Concrete_Entity that extends it and implement the necessary logic.
  
  
  
  Check for Implementations: Ensure that you have implemented the necessary logic in the concrete entity that you are trying to test. The concrete entity should provide the required fields and behavior.
  
  
  Testing the Concrete Entity: Once you have created a concrete entity, you can use the testing tools in SAP (like the ABAP Development Tools or transaction codes like SE11 or SE80) to test the concrete entity.
  
  
  Related Information:
  
  CDS Views: Core Data Services (CDS) is a framework for defining semantically rich data models in SAP. Abstract entities are part of this framework and are used to define reusable components.
  ABAP Development Tools: Familiarize yourself with the ABAP Development Tools (ADT) in Eclipse, which provides a more modern environment for developing and testing CDS views.
  Documentation: Refer to the official SAP documentation on CDS views and abstract entities for more detailed information on how to work with them.
  
  By following these steps, you should be able to resolve the error and successfully test your CDS views.
