Past Due Shipment Notification for Sales Order

Friends help pls

I have configured output determination for sales order header for customer notification if delivery is not created for the line item on the loading date of that line item, output should be triggered for the customer automatically.

Question; we don’t want to open and save the sales order in order to determine output for these sales orders as it’s time-consuming.

How to make it automatic so that system will pick up all past due sales orders and trigger output without manual intervention at the certain time of the day?.

Thanks in advance
