  • What is the cause and solution for SAP error message CNVA_20201_CHECK027 - The number range level is greater than a buffer of 100 numbers. ?

    The SAP error message CNVA_20201_CHECK027 indicates that the number range level is greater than a buffer of 100 numbers. This typically occurs in the context of number range management, where the system is trying to allocate a number from a number range object, but the buffer size is insufficient to handle the request.

    Cause:

    1. Number Range Configuration: The number range object may be configured with a buffer size that is too small for the volume of transactions being processed.
    2. High Transaction Volume: If there are many transactions occurring simultaneously, the system may exhaust the available numbers in the buffer.
    3. System Settings: The default settings for number range buffering may not be adequate for the specific business process or volume of data.

    Solution:

    1. Increase Buffer Size:

      • Go to the transaction code SNRO (Number Range Objects).
      • Find the relevant number range object that is causing the issue.
      • Check the buffer settings and increase the buffer size to accommodate more numbers. This can be done by adjusting the "Buffer Size" parameter.
    2. Check Number Range Status:

      • Ensure that the number range is not exhausted. You can check the status of the number range in the same SNRO transaction.
      • If the number range is exhausted, you may need to extend it by creating additional intervals or increasing the existing range.
    3. Monitor Transaction Volume:

      • If your business processes have increased in volume, consider monitoring the transaction load and adjusting the number range settings accordingly.
    4. Consult Documentation:

      • Review SAP documentation or notes related to number range management for best practices and recommendations.
    5. System Performance:

      • Ensure that the system performance is optimal, as performance issues can also lead to delays in number allocation.

    Related Information:

    • Transaction Codes:

      • SNRO: To manage number range objects.
      • SNUM: To display and manage number ranges.
    • SAP Notes: Check for any relevant SAP Notes that may address specific issues related to number range management.

    • SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.

    By following these steps, you should be able to resolve the error CNVA_20201_CHECK027 and ensure that your number range management is functioning correctly.
