• What is the cause and solution for SAP error message CFD_REPOSITORY_API006 - CDS View &1 is not registered for field extensibility. ?

  The SAP error message CFD_REPOSITORY_API006 indicates that a Core Data Services (CDS) view is not registered for field extensibility. This typically occurs when you are trying to extend a CDS view, but the view has not been configured to allow for such extensions.
  Cause:
  
  CDS View Not Registered for Extensibility: The CDS view you are trying to extend does not have the necessary annotations that allow it to be extended. This is often due to the absence of the @Extensible annotation or similar settings in the CDS definition.
  Incorrect Usage: You might be trying to extend a standard CDS view that is not designed for extensibility.
  Transport Issues: If the CDS view was recently created or modified, it may not have been properly transported or activated in the system.
  
  Solution:
  
  Check Annotations: Ensure that the CDS view has the appropriate annotations for extensibility. You should look for the @Extensible annotation in the CDS view definition. If it is missing, you may need to modify the CDS view to include it.
