• What is the cause and solution for SAP error message SADL_GW_DT_CDS008 - Do not use the virtual element &1 in the association definition. ?

  The SAP error message SADL_GW_DT_CDS008 indicates that there is an issue with the use of a virtual element in the association definition of a Core Data Services (CDS) view. Virtual elements are typically calculated fields or derived attributes that are not directly mapped to a database column. In the context of CDS views, they cannot be used in association definitions.
  Cause:
  The error occurs when you attempt to define an association in a CDS view that includes a virtual element. This is not allowed because associations are meant to establish relationships between entities based on actual database fields, and virtual elements do not have a direct representation in the database.
  Solution:
  To resolve this error, you should:
  
  
  Review the Association Definition: Check the association in your CDS view and identify where the virtual element is being used.
  
  
  Remove the Virtual Element: If the virtual element is part of the association, you need to remove it from the association definition. Instead, use actual database fields that are part of the underlying tables.
  
  
  Refactor the CDS View: If the virtual element is necessary for your business logic, consider refactoring your CDS view. You might need to create a separate CDS view that includes the virtual element and then use that view in your application logic without trying to establish an association based on it.
  
  
  Use Annotations: If you need to provide additional information or behavior related to the virtual element, consider using annotations instead of trying to include it in the association.
  
  
  Related Information:
  
  CDS Views: Core Data Services (CDS) are a way to define semantically rich data models in SAP. They allow for the definition of views that can include associations, annotations, and more.
  Virtual Elements: These are fields that are calculated at runtime and do not correspond to a physical column in the database. They are often used for derived calculations or aggregations.
  SAP Documentation: For more detailed information, refer to the official SAP documentation on CDS views and virtual elements, which provides guidelines on how to properly define associations and use virtual elements.
  
  By following these steps, you should be able to resolve the SADL_GW_DT_CDS008 error and successfully define your CDS view without using virtual elements in association definitions.
