Smart SAP Assistant

• What is the cause and solution for SAP error message NR091 - The year of an interval cannot be changed. ?

  The SAP error message NR091, "The year of an interval cannot be changed," typically occurs in the context of managing number ranges in SAP. This error indicates that there is an attempt to modify the year of a number range interval that is not allowed due to system constraints.
  Cause:
  
  Number Range Intervals: In SAP, number ranges are defined for various objects (like documents, invoices, etc.) and are often set up with specific intervals that include a year. Once a number range is created and used, changing the year of that interval is restricted to maintain data integrity.
  Usage of Number Ranges: If the number range has already been used (i.e., documents have been created using that number range), the system prevents changes to the year to avoid inconsistencies in document numbering.
  Configuration Settings: The configuration settings for number ranges may not allow changes to the year once the number range is active.
  
  Solution:
  
  Check Number Range Usage: Verify if the number range has been used. If it has, you cannot change the year. You may need to create a new number range interval for the new year instead.
  Create a New Interval: If you need to change the year, create a new number range interval for the desired year. This can be done in the number range configuration settings (Transaction code: SNRO or SNUM).
  Consult Documentation: Review the SAP documentation or help files related to number range management for specific instructions on how to handle number ranges.
  Authorization: Ensure that you have the necessary authorizations to make changes to number ranges. If not, contact your SAP administrator.
  System Settings: If you believe the change should be allowed, check with your SAP Basis or configuration team to see if there are any settings that can be adjusted.
