• What is the cause and solution for SAP error message NR128 - The "To Year" field must be initial since its flag is set to "off" ?

  The SAP error message NR128 indicates that there is an issue with the "To Year" field in a transaction related to number range management. This error typically occurs when you are trying to create or modify a number range interval, and the system expects the "To Year" field to be empty (initial) because the corresponding flag is set to "off."
  Cause:
  The error arises due to the following reasons:
  
  Configuration Issue: The number range interval is configured in such a way that the "To Year" field should not have a value when the flag is set to "off." This is often related to the settings in the number range object.
  Incorrect Input: The user may have inadvertently entered a value in the "To Year" field when it should be left blank.
  
  Solution:
  To resolve the NR128 error, you can follow these steps:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Find the relevant number range object that is causing the issue.
  Review the configuration settings for the number range intervals.
  Ensure that the "To Year" field is left blank if the flag is set to "off."
  
  
  
  Modify the Number Range Interval:
  
  If you are creating or modifying a number range interval, ensure that you do not enter any value in the "To Year" field if the flag indicates that it should be empty.
  Save the changes after making the necessary adjustments.
  
  
  
  Consult Documentation:
  
  If you are unsure about the configuration settings, refer to the SAP documentation or consult with your SAP Basis or functional team for guidance on the specific number range object.
  
  
  
  Testing:
