  The SAP error message KO319 indicates that you are trying to create or process an order of a specific order type that is configured to use external number assignment. This means that the system expects you to provide a specific order number rather than generating one automatically.
  Cause:

  You attempt to create a production order or a similar order type that is set to use external number assignment.
  You do not provide an order number when prompted, or the system does not generate one automatically.

  To resolve this error, you need to provide a valid order number when creating the order. Here are the steps you can take:
  
  
  Manually Enter an Order Number: When prompted for an order number, enter a valid number that adheres to the number range defined for that order type.
  
  
  Check Number Ranges: Ensure that the number range for the order type is correctly defined and that you are using a number that falls within that range. You can check this in the SAP configuration:

  Configuration Review: If you are responsible for system configuration, review the settings for the order type in the configuration:
  
  Use transaction code SPRO to access the SAP Reference IMG.
