NR138 - Details

• The SAP error message NR138 ("Number quantity greater than zero is invalid if 'no buffering' chosen") typically occurs in the context of number range management in SAP. This error indicates that there is an issue with the configuration of number ranges, particularly when the system is set to "no buffering" for a specific number range object.
  
  Cause:
  
  Number Range Configuration: The error arises when a number range is configured to not use buffering, but there is an attempt to assign a number from that range that is greater than zero. This can happen if the number range is exhausted or if the system is trying to allocate a number that is not available.
  Concurrency Issues: If multiple users or processes are trying to access the same number range simultaneously, it can lead to conflicts, especially when buffering is disabled.
  Incorrect Settings: The number range object may have been incorrectly set up, leading to inconsistencies
