• What is the cause and solution for SAP error message CNV_NCE_BAS454 - Target number range is not alphanumeric ?

  The SAP error message CNV_NCE_BAS454 indicates that there is an issue with the target number range being defined in a non-alphanumeric format. This error typically arises during data migration or conversion processes, particularly when using SAP's data migration tools.
  Cause:
  The error occurs when the target number range is expected to be alphanumeric (i.e., it should include both letters and numbers or just letters) but is instead defined in a format that does not meet this requirement. This can happen due to:
  
  Incorrect Configuration: The number range configuration in the target system may not be set up correctly.
  Data Format Issues: The data being migrated may contain values that are not compatible with the expected alphanumeric format.
  Mapping Errors: There may be issues in the mapping of source data to target fields, leading to incorrect data types being assigned.
  
  Solution:
  To resolve the CNV_NCE_BAS454 error, you can follow these steps:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects) in SAP.
  Verify the configuration of the number range object that is causing the issue. Ensure that it is set to accept alphanumeric values.
  
  
  
  Review Data Mapping:
  
  Check the mapping of the source data to the target fields in your migration tool. Ensure that the fields are correctly defined and that the data types match the expected formats.
  
  
  
  Data Validation:

  Adjust Migration Settings:
  
  If you are using a specific migration tool (like SAP S/4HANA Migration Cockpit or SAP Data Services), review the settings and configurations to ensure they are set up correctly for alphanumeric handling.
