• What is the cause and solution for SAP error message CSP_BDEF_CHECK012 - CDS view '&1' contains special client field '&2' of persistent table '&3' ?

  The SAP error message CSP_BDEF_CHECK012 indicates that there is an issue with a Core Data Services (CDS) view that contains a special client field. This error typically arises when the CDS view is trying to access a field that is not properly defined or is not allowed in the context of the view.
  Cause:
  
  Special Client Field: The error message indicates that the CDS view contains a special client field (usually a field that is used for client-specific data, such as the client ID in multi-client scenarios).
  Inappropriate Usage: The special client field is being used in a way that is not permitted within the context of the CDS view. This could be due to the view being defined in a way that does not align with the expected usage of client fields.
  Persistent Table Reference: The error also references a persistent table, indicating that the issue may stem from how the CDS view is defined in relation to the underlying database table.
  
  Solution:
  
  Review the CDS View Definition: Check the definition of the CDS view to ensure that it is correctly defined and that the special client field is being used appropriately. Make sure that the field is included in the correct context.
  Adjust the Client Field Usage: If the special client field is not necessary for the logic of the CDS view, consider removing it. If it is necessary, ensure that it is being used in a way that complies with SAP's guidelines for CDS views.
  Check Annotations: Ensure that the appropriate annotations are used in the CDS view definition. For example, if the view is intended to be client-specific, ensure that it is annotated correctly to reflect that.
  Consult Documentation: Refer to SAP documentation regarding CDS views and client fields to understand the best practices and restrictions related to their usage.
  Testing: After making changes, test the CDS view to ensure that the error is resolved and that the view behaves as expected.
