• What is the cause and solution for SAP error message SADL_GEN_DRFT_MSG401 - CDS-View &1 is not a BO-View. ?

  The SAP error message "SADL_GEN_DRFT_MSG401 CDS-View &1 is not a BO-View" typically occurs in the context of SAP's Business Object (BO) framework when working with Core Data Services (CDS) views. This error indicates that the specified CDS view is not recognized as a Business Object view, which is necessary for certain operations within the SAP system.
  Cause:
  
  Incorrect View Type: The CDS view you are trying to use is not defined as a Business Object view. BO views have specific annotations and structures that differentiate them from regular CDS views.
  Missing Annotations: The required annotations for a CDS view to be recognized as a BO view (such as @ObjectModel: { ... }) may be missing.
  View Definition Issues: There may be issues in the definition of the CDS view itself, such as incorrect syntax or missing elements that prevent it from being recognized as a BO view.
  Transport Issues: If the CDS view was recently transported from another system, it may not have been activated correctly in the target system.
  
  Solution:
  
  
  Check Annotations: Ensure that the CDS view has the necessary annotations to be recognized as a Business Object view. For example, it should include annotations like @ObjectModel: { ... } that define it as a BO view.
  Example:
  @AbapCatalog.sqlViewName: 'Z_MY_CDS_VIEW'
  @ObjectModel: { ... }
  define view Z_MY_CDS_VIEW as select from ...
  
  
  Review View Definition: Go through the CDS view definition to ensure that it adheres to the required structure and syntax. Make sure all necessary fields and associations are correctly defined.
  
  
  Activate the View: If the view has been recently created or modified, ensure that it is activated in the ABAP Development Tools (ADT) or the SAP GUI.
  
  
  Check for Dependencies: Ensure that any dependent objects (like tables or other views) are also active and correctly defined.
  
  
  Consult Documentation: Refer to SAP documentation or the SAP Help Portal for specific guidelines on creating BO views and the required annotations.
  
  
  Debugging: If the issue persists, consider debugging the application or transaction that is triggering the error to gather more context about why the view is not being recognized.
