  The SAP error message CNV_NCE_BAS453 indicates that there is a conflict with another unique target number range interval during a data migration or conversion process. This typically occurs in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion scenarios.
  Cause:
  The error arises when the system detects that the target number range you are trying to use for a specific object (like a document, customer, vendor, etc.) overlaps with an existing number range that is already defined in the system. This can happen if:
  
  You are trying to assign a number range that is already in use by another object.
  There are conflicting settings in the configuration of number ranges.
  The number range intervals are not properly defined or have been incorrectly set up.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing Number Ranges:
  
  Go to the transaction code SNRO (Number Range Objects) and check the number range objects related to the data you are migrating.
  Identify the existing number ranges and their intervals to see if there is an overlap with the one you are trying to use.
  
  
  
  Adjust Number Ranges:
  
  If you find that the number range you are trying to use conflicts with an existing one, you will need to either:

  Review Configuration:
  
  Ensure that the configuration for the number ranges is correct and that there are no unintended overlaps.
  Check if there are any custom developments or enhancements that might be affecting the number range assignments.
  
  
  
  Test the Changes:
  
  After making adjustments, re-run the migration or conversion process to see if the error persists.
