• What is the cause and solution for SAP error message CNV_NCE_BAS467 - Mapping values result in &1 numbers moving from range &2 to range &3 ?

  The SAP error message CNV_NCE_BAS467 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or similar tools. This error indicates that there is an issue with the mapping of values from one range to another, which can lead to inconsistencies or data integrity issues.
  Cause:
  The error message CNV_NCE_BAS467 is triggered when the mapping of values results in a situation where a certain number of records (indicated by &1) are being moved from one defined range (indicated by &2) to another range (indicated by &3). This can happen due to several reasons:
  
  Incorrect Mapping Configuration: The mapping rules defined for the data conversion may not align correctly with the source and target data structures.
  Data Type Mismatch: The data types of the source and target fields may not be compatible, leading to unexpected value ranges.
  Data Quality Issues: The source data may contain values that do not fit into the expected ranges of the target fields.
  Business Logic Changes: Changes in business logic or requirements may have altered the expected value ranges.
  
  Solution:
  To resolve the CNV_NCE_BAS467 error, you can take the following steps:
  
  
  Review Mapping Configuration:
  
  Check the mapping rules defined in the migration tool. Ensure that the source and target fields are correctly mapped and that the value ranges are appropriate.
  
  
  
  Validate Data Types:
  
  Ensure that the data types of the source and target fields are compatible. If necessary, adjust the data types or perform data transformations to align them.
  
  
  
  Analyze Source Data:
  
  Review the source data for any anomalies or values that fall outside the expected ranges. Cleanse the data if necessary to ensure it meets the target requirements.
  
  
  
  Adjust Value Ranges:
  
  If the target range is too restrictive, consider adjusting it to accommodate the incoming data. This may involve changing the configuration in the target system.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration tool you are using. There may be specific guidelines or known issues that can help you troubleshoot the error.
  
  
  
  Testing:
  
  After making adjustments, perform a test migration with a smaller dataset to verify that the changes resolve the issue before proceeding with the full migration.
