• What is the cause and solution for SAP error message APS_CCV_SCENARIO002 - Exposure of non-customer CDS view: Not allowed for an External API. ?

  The SAP error message APS_CCV_SCENARIO002, which states "Exposure of non-customer CDS view: Not allowed for an External API," typically occurs when there is an attempt to expose a Core Data Services (CDS) view that is not intended for external consumption through an API. This is a common issue when working with SAP's Cloud Application Programming (CAP) model or when developing OData services.
  Cause:
  
  Non-Customer CDS View: The CDS view you are trying to expose is not marked as a customer view. In SAP, certain CDS views are designed for internal use only and are not meant to be exposed externally.
  API Exposure Restrictions: SAP has specific guidelines and restrictions regarding which CDS views can be exposed as APIs. If a CDS view is not intended for external use, it will trigger this error when you attempt to expose it.
  
  Solution:
  
  Check the CDS View: Review the definition of the CDS view in question. Ensure that it is intended for external use. You can do this by checking the annotations and the view's purpose.
  Use a Customer-Defined CDS View: If the CDS view is not meant for external use, consider creating a new CDS view that is specifically designed for external consumption. You can base it on the existing view but ensure it is marked appropriately.
  Annotations: Ensure that the CDS view has the correct annotations for exposure. For example, it should have the @OData.publish: true annotation if you want to expose it as an OData service.
  Consult Documentation: Refer to the SAP documentation for guidelines on creating and exposing CDS views. This will help you understand the requirements and limitations.
  Check Authorization: Ensure that you have the necessary authorizations to expose the CDS view. Sometimes, authorization issues can also lead to similar error messages.
