• What is the cause and solution for SAP error message CNV_NCE_BAS436 - Number range intervals for object &1 were changed ?

  The SAP error message CNV_NCE_BAS436 indicates that the number range intervals for a specific object (denoted by &1) have been changed. This message is typically encountered during data migration or conversion processes, particularly when using SAP's Conversion Tools or during system upgrades.
  Cause:
  The error usually arises due to one of the following reasons:
  
  Changes in Number Ranges: The number range intervals for the specified object have been modified after the initial setup, which can lead to inconsistencies in the data migration process.
  Configuration Issues: There may be discrepancies in the configuration settings related to number ranges, especially if multiple systems or clients are involved.
  Data Migration Tools: If you are using SAP's data migration tools (like SAP S/4HANA Migration Cockpit or other conversion tools), the tool may detect that the number range intervals have been altered since the last execution.
  
  Solution:
  To resolve this 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 specific object mentioned in the error message.
  Ensure that the number range intervals are correctly defined and have not been altered unexpectedly.
  
  
  
  Review Change Logs:
  
  If possible, review the change logs to identify when and why the number range intervals were modified. This can help in understanding the context of the changes.
  
  
  
  Reconfigure Number Ranges:
  
  If the number ranges need to be reset or reconfigured, make the necessary adjustments in the SNRO transaction.
  Ensure that the intervals are set correctly and that they do not overlap with other objects.
  
  
  
  Restart the Migration Process:
  
  After making the necessary changes, restart the data migration or conversion process to see if the error persists.
  
  
  
  Consult Documentation:
