• What is the cause and solution for SAP error message ITOB307 - Number range & is not an external number range ?

  The SAP error message ITOB307 indicates that the number range you are trying to use is not defined as an external number range. This typically occurs when you are attempting to create or process an object (like a document or a transaction) that requires a number from a number range that is set up to be internal rather than external.
  Cause:
  
  Number Range Configuration: The number range you are trying to use is configured as an internal number range in the system. Internal number ranges are automatically generated by the system, while external number ranges require manual input.
  Incorrect Number Range Assignment: The transaction or document type you are working with may be incorrectly assigned to a number range that is not set up for external use.
  User Input: If you are trying to manually enter a number in a field that is supposed to use an external number range, and the system is configured to use an internal number range, this error will occur.
  
  Solution:
  
  
  Check Number Range Configuration:
  
  Go to the transaction code SNRO (Number Range Objects).
  Find the relevant number range object and check its configuration.
  Ensure that the number range is set up as an external number range if you intend to use it that way.
  
  
  
  Change Number Range Assignment:
  
  If the number range is incorrectly assigned, you may need to change the assignment in the relevant configuration settings (e.g., in the customizing settings for the specific application area).
  Use transaction code SPRO to navigate to the relevant configuration area and adjust the number range settings.
  
  
  
  Use Internal Number Range:
  
  If you do not need to use an external number range, you can simply allow the system to generate the number automatically. Ensure that you are not trying to manually input a number when the system is set to use an internal number range.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation or help files related to number range management for more detailed guidance on configuring number ranges.
