  The SAP error message CNV20400217 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that a specific field (denoted by &1 and &2) is excluded from a split operation because the field's NOTUSE flag is set to 'X', but it is still being converted in a merge operation.
  Cause:
  
  Field Configuration: The field in question has been marked as "not used" (NOTUSE='X') in the source system or in the migration configuration. This means that the field is not intended to be processed during the split operation.
  Data Migration Logic: The migration logic is attempting to process this field in a merge operation despite it being excluded from the split, which leads to a conflict.
  
  Solution:
  
  Review Field Configuration: Check the configuration of the field in the source system. If the field is not supposed to be used, ensure that it is correctly marked as NOTUSE in the migration settings.
  Adjust Migration Settings: If the field is needed for the migration, you may need to adjust the migration settings to ensure that it is included in the split operation. This may involve changing the NOTUSE flag or modifying the mapping rules.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be guidelines on how to handle fields marked as NOTUSE.
  Data Validation: Ensure that the data being migrated does not contain inconsistencies or errors that could lead to this issue. Validate the data in the source system before migration.
  Contact SAP Support: If the issue persists and you cannot resolve it through configuration changes, consider reaching out to SAP support for assistance.
