• What is the cause and solution for SAP error message APS_CKE_PARSER078 - &1 exposes non-customer CDS view. This is not allowed for an External API ?

  The SAP error message APS_CKE_PARSER078 indicates that a non-customer CDS (Core Data Services) view is being exposed through an external API, which is not permitted. This error typically arises when trying to expose a CDS view that is not intended for external consumption, often due to security or data integrity concerns.
  Cause:
  
  Non-Customer CDS View: The CDS view you are trying to expose is either a standard SAP view or a view that is not marked as customer-specific. SAP restricts the exposure of such views to ensure that sensitive or proprietary data is not inadvertently shared with external systems.
  API Configuration: The API configuration may be incorrectly set up to include views that are not allowed for external access.
  
  Solution:
  
  Check the CDS View: Review the CDS view definition to determine if it is a standard SAP view. If it is, you will need to create a customer-specific version of the view or use a different view that is designed for external access.
  Create a Customer-Specific CDS View: If you need to expose specific data, consider creating a new CDS view that is based on the existing one but is marked as customer-specific. You can do this by using the @AbapCatalog.sqlViewName annotation and ensuring that the view is defined in a way that allows for external access.
  Review API Definition: Ensure that the API definition is correctly set up to only include views that are allowed for external consumption. This may involve modifying the API to exclude the problematic CDS view.
  Consult Documentation: Refer to SAP documentation regarding CDS views and external APIs to understand the guidelines and restrictions for exposing data.
  
  Related Information:
  
  CDS Views: Core Data Services are a way to define semantically rich data models in SAP. They can be used to create database views that can be consumed by various applications, including Fiori apps and OData services.
  External APIs: When exposing data through APIs, it is crucial to ensure that only the appropriate data is shared, adhering to security and compliance standards.
  SAP Notes and Community: Check SAP Notes for any specific guidance or updates related to this error message. The SAP Community forums can also be a valuable resource for troubleshooting and finding solutions from other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the error and successfully expose the required data through an external API.
