• What is the cause and solution for SAP error message CNV_NCE_BAS022 - &1 Range &2 &3: pattern results in duplicate numbers ?

  The SAP error message CNV_NCE_BAS022 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 there is a problem with the number range configuration, specifically that the defined pattern for generating numbers results in duplicates.
  Cause:
  The error message indicates that the number range defined for a certain object or entity is not unique. This can happen due to several reasons:
  
  Overlapping Number Ranges: Two or more number ranges may overlap, causing the system to generate the same number for different records.
  Incorrect Configuration: The number range configuration might be set up incorrectly, leading to patterns that can produce duplicate values.
  Data Migration Issues: During data migration, if the source data contains duplicates or if the mapping is not correctly defined, it can lead to this error.
  
  Solution:
  To resolve the CNV_NCE_BAS022 error, you can take the following steps:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects) and check the configuration for the relevant number range object.
  Ensure that the number ranges do not overlap and are correctly defined.
  
  
  
  Review Data Mapping:
  
  If you are migrating data, review the mapping of source data to target fields. Ensure that the source data does not contain duplicates that could conflict with the target number range.
  
  
  
  Adjust Patterns:
  
  If the error is related to a specific pattern, consider adjusting the pattern to ensure it generates unique numbers. This may involve changing the starting point or increment of the number range.
  
  
  
  Data Cleansing:
  
  If duplicates exist in the source data, perform data cleansing to remove or resolve duplicates before migration.
  
  
  
  Testing:
  
  After making changes, perform a test migration to ensure that the error does not occur again.
  
  
  
  Consult Documentation:
