  The SAP error message CNV_NCE_BAS123 indicates that changes have been detected in the table NRIV, which is related to number range intervals. This error typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools.
  Cause:
  The error arises when the system detects that the number range intervals (stored in the NRIV table) have been modified after the initial mapping or conversion process was set up. This can happen due to:
  
  Changes in Number Ranges: If number ranges have been added, deleted, or modified in the NRIV table after the initial mapping was created.
  Concurrent Changes: Other processes or users may have made changes to the number ranges while the migration or conversion process was ongoing.
  Inconsistent Data: The data in the NRIV table may not match the expected state for the migration process.
  
  Solution:
  To resolve this error, you will need to reinitialize the mappings for the affected number ranges. Here are the steps you can follow:
  
  
  Check NRIV Table: Review the NRIV table to identify any changes that have been made. You can do this by executing a query in the SAP database to see the current state of number ranges.
  
  
  Reinitialize Mappings:
  
  Go to the transaction or tool you are using for the migration (e.g., SAP S/4HANA Migration Cockpit).
  Look for an option to reinitialize or refresh the mappings related to number ranges.
  Follow the prompts to reinitialize the mappings.
  
  
  
  Review Logs: After reinitializing, check the logs for any additional errors or warnings that may need to be addressed.
  
  
  Test Migration: Once the mappings have been reinitialized, perform a test migration to ensure that the error has been resolved and that the data is being processed correctly.
  
  
  Consult Documentation: If the issue persists, refer to the SAP documentation or notes related to the specific migration tool you are using for any additional troubleshooting steps.
