Order header status update and hold are two business event trigger points that can be used to enable e-mail notifications.A business event trigger point is a condition that triggers a business event, which is a notification that informs subscribers about a significant development in the order-to-cash process1.You can use the Manage Business Event Trigger Points page to set up the criteria that uses the Sales Order Notification business event to send e-mail notifications to subscribers2.The following are some examples of business event trigger points that you can use3:

Order header status update: This trigger point sends a notification when the status of the order header changes, such as from Entered to Booked, or from Booked to Closed.

Hold: This trigger point sends a notification when a hold is applied to or released from an order or a fulfillment line. A hold is a condition that prevents the fulfillment of an order or a line until it is resolved.

Split: This trigger point sends a notification when a fulfillment line is split into two or more lines. A split can occur due to various reasons, such as partial fulfillment, backorder, or change order.

Change order compensation complete: This trigger point sends a notification when the compensation process for a change order is completed. A change order is a request to modify an existing order, such as adding, deleting, or updating lines. A compensation process is a set of actions that adjust the fulfillment plan and the pricing of the order to reflect the changes.

Order attribute update: This trigger point sends a notification when a predefined attribute on the order header or the fulfillment line is updated, such as the order type, the customer, or the ship-to location.
