• What is the cause and solution for SAP error message CNV_10210102 - &1 number range mapping values found ?

  The SAP error message CNV_10210102 typically relates to issues with number range mapping during data migration or conversion processes, particularly in the context of SAP's Conversion Tools (like SAP S/4HANA Migration Cockpit or other data migration tools). The message indicates that there are multiple number range mapping values found for a specific object or entity, which can lead to conflicts or inconsistencies in the data being processed.
  Cause:
  
  Duplicate Number Ranges: The error often arises when there are duplicate entries in the number range mapping table. This can happen if the same number range is assigned to multiple objects or if there are overlapping ranges.
  Incorrect Configuration: The number range mapping may not be correctly configured, leading to ambiguity in how numbers are assigned during the migration process.
  Data Integrity Issues: If the source data has inconsistencies or if the mapping does not align with the target system's expectations, this error can occur.
  
  Solution:
  
  
  Check Number Range Mapping:
  
  Go to the transaction code SNRO (Number Range Objects) and review the number range objects involved in the migration.
  Ensure that there are no duplicate entries or overlapping ranges in the mapping configuration.
  
  
  
  Adjust Mapping Configuration:
  
  If duplicates are found, adjust the mapping to ensure that each object has a unique number range assigned.
  Make sure that the number ranges are correctly defined and that they correspond to the target system's requirements.
  
  
  
  Review Migration Settings:
  
  Check the settings in the migration tool you are using (e.g., SAP S/4HANA Migration Cockpit) to ensure that the number range mapping is correctly set up.
  Validate that the source data aligns with the expected formats and ranges in the target system.
  
  
  
  Test Migration:
  
  After making adjustments, perform a test migration to ensure that the changes resolve the issue.
  Monitor the logs for any further errors or warnings related to number range mapping.
