How To Fix CNV_NCE_BAS151 - NR interval &1: source and target NR intervals are not identical

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_NCE_BAS - Number conversion engine: messages

• Message number: 151

• Message text: NR interval &1: source and target NR intervals are not identical

What causes this issue?

You have chosen the rule 'No conversion' or 'One-to-one' for the
corresponding number range interval, but the target number range
interval number or year differs from the source one. Since these
conversion rules do not result in the renumbering of numbers, the target
interval must be the same as the source one.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Change the target number range interval number or year so that it is the
same as the source one.

• What is the cause and solution for SAP error message CNV_NCE_BAS151 - NR interval &1: source and target NR intervals are not identical ?

  The SAP error message CNV_NCE_BAS151 indicates that there is a mismatch between the number range (NR) intervals defined for the source and target systems during a data migration or conversion process. This error typically arises in the context of using SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other data conversion tools.
  Cause:
  The error occurs when:
  
  The number range intervals defined in the source system do not match those defined in the target system.
  There may be gaps, overlaps, or completely different intervals for the same object type in the source and target systems.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Number Ranges:
  
  Verify the number range intervals in both the source and target systems. You can do this by navigating to the relevant configuration settings in SAP.
  Use transaction codes like SNRO (Number Range Objects) to check the number range objects and their intervals.
  
  
  
  Align Number Ranges:
  
  If you find discrepancies, you will need to align the number ranges. This may involve:
  
  Creating new number ranges in the target system that match those in the source system.
  Adjusting the existing number ranges in the target system to ensure they are identical to those in the source system.
  
  
  
  
  
  Adjust Migration Settings:
  
  If the number ranges cannot be aligned due to business requirements, you may need to adjust the migration settings to accommodate the differences. This could involve mapping the source number ranges to different target number ranges.
  
  
  
  Test the Migration:
  
  After making the necessary adjustments, perform a test migration to ensure that the error does not occur again.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration tool you are using for any additional guidance or best practices.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SNRO: To manage number range objects.
  SNUM: To display number ranges.
  
  
  
  SAP Notes:
  
  Check for any relevant SAP Notes that may provide additional insights or solutions related to number range issues during migration.
  
  
  
  Migration Tools:
  
  Familiarize yourself with the specific migration tool you are using, as different tools may have different requirements or settings related to number ranges.
  
  
  
  By following these steps, you should be able to resolve the CNV_NCE_BAS151 error and successfully complete your data migration or conversion process.
