  • What is the cause and solution for SAP error message TT105 - Number range overflow, creation not possible ?

    The SAP error message TT105, which indicates "Number range overflow, creation not possible," typically occurs when a number range object has exhausted its available number range. This can happen in various contexts, such as when creating new documents, records, or transactions that rely on a specific number range.

    Cause:

    1. Exhausted Number Range: The most common cause is that the defined number range for a specific object has reached its maximum limit. For example, if the number range is defined from 1 to 1000, and all numbers have been used, any attempt to create a new record will trigger this error.
    2. Incorrect Configuration: Sometimes, the number range may not be configured correctly, leading to premature exhaustion.
    3. Missing Number Range: If the number range is not defined for the object in question, it can also lead to this error.

    Solution:

    1. Extend the Number Range:

      • Go to the transaction code SNRO (Number Range Objects).
      • Find the relevant number range object associated with the error.
      • Check the current number range intervals and extend them if necessary. You can create a new interval with a higher upper limit.
      • Make sure to activate the new number range if required.
    2. Check for Existing Intervals:

      • Ensure that there are no existing intervals that can still be used. Sometimes, there may be gaps in the number range that can be utilized.
    3. Review Configuration:

      • Review the configuration settings for the number range object to ensure that it is set up correctly and that there are no restrictions that could lead to an overflow.
    4. Consult Documentation:

      • Refer to SAP documentation or consult with your SAP Basis or functional team for specific guidance related to the number range object in question.
    5. Testing:

      • After making changes, test the creation of the document or record again to ensure that the issue is resolved.

    Related Information:

    • Transaction Codes:
      • SNRO: To manage number range objects.
      • SNUM: To display number ranges.
    • Number Range Management: Understanding how number ranges work in SAP is crucial. Each object that requires a unique identifier typically has a number range associated with it.
    • User Authorizations: Ensure that the user has the necessary authorizations to modify number ranges, as this may be restricted in some environments.

    If the problem persists after following these steps, it may be necessary to consult with SAP support or your internal SAP team for further investigation.
