The OrderDeliveryMethod and Locations objects have their tabs set to Tab Hidden by default. These objects are used to store information about how an order is delivered and where it is fulfilled from, respectively. They are not meant to be accessed directly by users, but rather through related lists or lookup fields on other objects. Reference:Order Management Objects

The administrator can use two tools to debug an issue with an Apex trigger: Log Inspector in the Developer Console and Debug Logs in Setup. The Log Inspector is a tool that displays a graphical representation of a debug log, which is a record of database operations, system processes, and errors that occur when executing a transaction or running unit tests. The Log Inspector helps you analyze and troubleshoot your code by highlighting errors, checkpoints, and execution times. The Debug Logs page in Setup lets you monitor and retain debug logs for users, Apex classes, Apex triggers, and Lightning components. You can view, download, or delete debug logs from this page.

The Order Summary object is a custom object that stores information about an order, such as the total amount, the number of items, and the fulfillment status. The Order Summary object is created by a process called Create Order Summary Process, which runs whenever an order is created or updated. The process calls a flow called Create OrderSummary Flow, which calculates the order summary fields and creates or updates the order summary record. The process and the flow are part of the Order Management package and must be installed and activated for the order summary object to be created.

Debugging a flow with input data allows the administrator to test the flow with specific values and see how the flow behaves. The Debug with inputs option is available in the Flow Builder toolbar and lets the administrator provide input values for each flow variable before running the flow.

The feature that supports this use case is the Unmanaged Order Checkbox. This is a standard field on the Order Summary object that indicates whether the order is managed by Order Management or not. If this field is checked, then the order is not actioned on by Order Management, and it does not trigger any flows or processes. The administrator can use this field to import Order Summary records containing historical data without affecting the order lifecycle.
