• What is the cause and solution for SAP error message CNV_NCE_BAS468 - Mapping values result in &1 numbers moving outside of range &2 ?

  The SAP error message CNV_NCE_BAS468 typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that the mapping values being processed are resulting in numbers that exceed the defined range for a particular field.
  Cause:
  The error message CNV_NCE_BAS468 is triggered when:
  
  The data being migrated contains values that, after mapping, fall outside the acceptable range for the target field in the SAP system.
  The mapping logic or transformation rules applied to the data may not be correctly defined, leading to invalid values.
  The source data may contain unexpected or invalid values that do not conform to the target field's constraints.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Mapping Rules:
  
  Check the mapping rules defined in the migration project. Ensure that the transformation logic is correctly defined and that it adheres to the constraints of the target fields.
  
  
  
  Validate Source Data:
  
  Inspect the source data for any values that may be out of range. This includes checking for null values, negative numbers, or values that exceed the maximum limit defined for the target field.
  
  
  
  Adjust Data Types:
  
  If the target field has a specific data type (e.g., integer, decimal), ensure that the source data is compatible. You may need to adjust the data type or format of the source data before migration.
  
  
  
  Modify Target Field Settings:
  
  If appropriate, consider adjusting the settings of the target field in the SAP system to accommodate the incoming data. This may involve changing the field's data type or increasing its range.
  
  
  
  Test with Sample Data:
  
  Before running the full migration, test the mapping with a smaller subset of data to identify any potential issues. This can help isolate the problem and allow for easier troubleshooting.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration tool you are using. There may be additional guidelines or known issues that can provide further insights.
  
  
  
  Engage SAP Support:
  
  If the issue persists after trying the above steps, consider reaching out to SAP support for assistance. They may have additional tools or insights to help resolve the issue.
