• What is the cause and solution for SAP error message CNV_NCE_BAS147 - NR interval &1: offset mode is not possible ?

  The SAP error message CNV_NCE_BAS147 with the description "NR interval &1: offset mode is not possible" typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error is related to the handling of number ranges (NR) in the system.
  Cause:
  The error indicates that there is an issue with the configuration of number ranges, specifically when the system is trying to use an "offset mode" for a number range interval that does not support it. This can happen due to several reasons:
  
  Incorrect Number Range Configuration: The number range interval may not be set up correctly in the system, or it may not be compatible with the offset mode.
  Incompatible Settings: The number range object may have settings that do not allow for offset mode, which is typically used for generating unique numbers based on a specified offset.
  Data Migration Settings: The settings in the data migration tool may be incorrectly configured, leading to the attempt to use an unsupported mode for the specified number range.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Number Range Configuration:
  
  Go to transaction SNRO (Number Range Objects) and check the configuration of the number range object that is causing the issue.
  Ensure that the number range intervals are correctly defined and that the settings allow for the intended mode of operation.
  
  
  
  Review Migration Settings:
  
  If you are using a migration tool, review the settings related to number range handling. Ensure that the correct number range intervals are selected and that they are compatible with the data being migrated.
  
  
  
  Adjust Offset Mode:
  
  If the number range interval is not compatible with offset mode, consider switching to a different mode that is supported, or adjust the number range settings to allow for offset mode if appropriate.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to number range handling and data migration for any specific guidelines or recommendations.
