• What is the cause and solution for SAP error message RSRTS_CDS104 - Where clause: &1 is not a characteristic key ?

  The SAP error message RSRTS_CDS104 typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are trying to execute a query or a report that involves a CDS (Core Data Services) view, and there is an issue with the WHERE clause of the query. The specific message indicates that a certain field (represented by &1) is not recognized as a characteristic key.
  Cause:
  
  Incorrect Field Usage: The field specified in the WHERE clause is not defined as a characteristic in the underlying data model. This could happen if you are trying to filter on a field that is not part of the key figures or characteristics of the CDS view.
  Modeling Issues: There may be a problem with how the CDS view is modeled. For example, the field might not be included in the projection of the CDS view or might not be properly annotated.
  Typographical Errors: There could be a typo in the field name used in the WHERE clause, leading to the system not recognizing it as a valid characteristic.
  
  Solution:
  
  Check the Field Definition: Verify that the field you are using in the WHERE clause is indeed defined as a characteristic in the CDS view. You can do this by checking the CDS view definition in the ABAP Development Tools or in the SAP HANA Studio.
  Modify the Query: If the field is not a characteristic, consider modifying your query to use a valid characteristic or key figure. Ensure that you are using the correct field names as defined in the CDS view.
  Review the CDS View: If you have access to the CDS view definition, review it to ensure that all necessary fields are included and properly annotated. You may need to adjust the view to include the required fields.
  Consult Documentation: Refer to the SAP documentation for the specific CDS view you are working with to understand its structure and the fields it exposes.
  Testing: After making changes, test the query again to ensure that the error is resolved.
