• What is the cause and solution for SAP error message CNV_NCE_BAS226 - NR interval &1: internal alphanumeric intervals not allowed ?

  The SAP error message CNV_NCE_BAS226 with the description "NR interval &1: internal alphanumeric intervals not allowed" typically occurs during data conversion processes, particularly when using the SAP Data Migration tools or during the execution of certain programs that involve number ranges.
  Cause:
  This error indicates that there is an attempt to use an alphanumeric interval for a number range object where only numeric intervals are allowed. In SAP, number ranges are expected to be strictly numeric, and if the system encounters an alphanumeric value in a context where it expects a numeric value, it will throw this error.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Identify the number range object that is causing the issue.
  Ensure that the intervals defined for this number range object are purely numeric. If any alphanumeric values are present, they need to be corrected to numeric values.
  
  
  
  Review Data Migration Settings:
  
  If this error occurs during a data migration process, review the mapping and transformation rules to ensure that the values being migrated into the number range are numeric.
  Check the source data for any alphanumeric entries that may be incorrectly mapped to a numeric field.
  
  
  
  Adjust the Data:
  
  If you find any alphanumeric values in the data that should be numeric, you will need to clean or transform the data before attempting the migration or execution again.
  
  
  
  Testing:
  
  After making the necessary adjustments, re-run the process that triggered the error to confirm that the issue has been resolved.
