Hi @BeaLauraA. How are you doing the customer order delivery? If its via shipments please try below settings.
Change 1 - Shipment type
Shipment type > After the Delivery > Add an Optional Event to “Print the shipment Delivery note”
Change 2 - Customer (Internal Customer)
Customer > Sales > Message Defaults > Enable “Send Multi-Tier Delivery Notification Automate
Change 3 - Demand Site
Site > Sales and Procurement > Procurement Tab > Message Defaults > Change as Automatically in “Approval of Incoming Delivery Notification”
Let me know the outcome.
Thanks,
Chamath
