• What is the cause and solution for SAP error message DNO003 - External number assignment, enter notification number ?

  The SAP error message DNO003 ("External number assignment, enter notification number") typically occurs when you are trying to create or process a notification in SAP, but the system requires you to enter a notification number manually. This is often related to the configuration of number ranges for notifications in the system.
  Cause:
  
  External Number Assignment: The system is configured to use external number assignment for notifications, meaning that users must manually enter a notification number instead of the system generating one automatically.
  Number Range Configuration: The number range for notifications may not be properly set up or may be exhausted.
  User Authorization: The user may not have the necessary authorization to create a notification with an automatically assigned number.
  
  Solution:
  
  Enter Notification Number: If the system is set to external number assignment, you need to manually enter a valid notification number when prompted.
  Check Number Range Configuration:
  
  Go to transaction code SNRO (Number Range Objects).
  Look for the object related to notifications (e.g., QMEL for Quality Notifications).
  Ensure that the number range is defined and that there are available numbers in the range.
  
  
  Change to Internal Number Assignment (if applicable):
  
  If you prefer to use internal number assignment, you can change the configuration in the customizing settings.
  Go to transaction code SPRO and navigate to:
  
  Cross-Application Components > General Application Functions > Number Ranges > Define Number Ranges.
  
  
  Change the settings for the notification type you are working with to use internal number assignment.
  
  
  Check User Authorizations: Ensure that the user has the necessary authorizations to create notifications. This can be checked in transaction code SU53 after the error occurs.
