Three possible causes of this issue are:

• The administrator has duplicate Product SKUs in the JSON query. A Product SKU is a unique identifier for a product that is used to track inventory and sales. A Product SKU must be unique within an org, and it cannot be duplicated in a composite API call. If the administrator has duplicate Product SKUs in the JSON query, it will cause an error when loading test orders via the Workbench.
• The number of subrequests in the JSON query exceeds the 20 subrequest limit. A subrequest is a single HTTP request that is part of a composite API call. A composite API call can contain up to 20 subrequests in a single JSON body. If the administrator has more than 20 subrequests in the JSON query, it will cause an error when loading test orders via the Workbench.
• Record IDs used within the request are incorrect. A record ID is a unique identifier for a record that is used to reference and manipulate data in Salesforce. A record ID must be valid and exist in the org, and it must match the data type and format of the corresponding field. If the administrator has incorrect record IDs in the JSON query, such as using 15-character IDs instead of 18-character IDs, or using IDs from a different org, it will cause an error when loading test orders via the Workbench.

Three objects that are likely to get created in Order Management as an order progresses through its lifecycle are:

• Fulfillment Order. A Fulfillment Order is a record that represents a group of products in an order that are fulfilled together from the same location. A Fulfillment Order has a lookup relationship to the Order Summary object, and it contains information such as the fulfillment location, delivery method, status, etc.
• Return Order. A Return Order is a record that represents a return request for an order or part of an order. A Return Order has a lookup relationship to both Order Summary and Change Order objects, and it contains information such as the return reason, status, date, etc.
• Change Order. A Change Order is a record that represents a change request for an order or part of an order. A Change Order has a lookup relationship to the Order Summary object, and it contains information such as the change type, status, date, etc.

Two reasons for using Flows instead of Apex code are:

• Flows can be modified and created without a developer. Flows are declarative tools that allow administrators to build complex business logic using clicks instead of code. Flows do not require any programming skills or knowledge, and they can be easily modified and maintained by administrators.
• Flows provide a visual debug process. Flows have a built-in debugger that allows administrators to test and troubleshoot their flows in a graphical interface. The debugger shows the flow execution path, the values of variables and sObject fields, and any errors or warnings that occur in the flow.

The Ensure Funds process works on only the items passed into the Ensure Funds method. This method is a flow core action that verifies that there are enough funds available for each Order Item passed into it, and updates their payment status accordingly. The administrator can passany Order Items into this method, regardless of their status or delivery group.

The best place for a service agent to go first to view process exceptions related to a specific Order is the Order Record - Process Exception Details Tab. This tab shows a list of process exceptions that occurred during the order lifecycle, such as errors in payment authorization, inventory allocation, fulfillment location assignment, etc. The service agent can use this tab to identify and resolve the issues that affect the order processing.

The object record that the administrator should create in the fault path to notify users of an error is Process Exception. A Process Exception is a record that represents an error or exception that occurred during the order lifecycle, such as payment authorization failure, inventory allocation failure, fulfillment location assignment failure, etc. A Process Exception has a lookup relationship to the Order object, and it contains information such as the exception type, status, message, etc. Verified References:https://help.salesforce.com/s/articleView?id=sf.order_management_process_exception.htm &type=5

The object that the administrator should look at to find payment information about a returned item on an Order Summary is Credit Memo. A Credit Memo is a record that represents a refund or credit issued to a customer for a returned item. A Credit Memo has a lookup relationship to both Order Summary and Return Order objects, and it contains information such as the credit amount, status, payment method, etc. Verified References:https://help.salesforce.com/s/articleView?id=sf.order_management_credit_memo.htm &type=5

Two APIs that an admin can suggest so that customers can initiate order cancellations and returns from the B2C Commerce storefront and have their action carry out the cancel and return operations in Order Management are:

• Connect APIs. These are RESTful APIs that expose resources in Order Management, such as orders, payments, shipments, etc. They allow customers to perform CRUD (create, read, update, delete) operations on these resources from external systems, such as B2C Commerce.
• REST APIs. These are HTTP-based APIs that enable developers to access data in Order Management using standard HTTP methods, such as GET, POST, PUT, PATCH, and DELETE. They allow customers to interact with Order Management resources using JSON or XML formats.

Three steps that are required when deploying changes via change sets are:

• Create the change set in the sandbox org. This is the first step where the administrator selects the metadata components that they want to deploy and adds them to a change set in the source org, which is usually a sandbox org.
• Upload the change set to the target org. This is the second step where the administrator sends the change set from the source org to the destination org, which is usually a production org or another sandbox org. The administrator needs to have a deployment connection with the target org and permission to upload change sets.
• Deploy the change set in the target org. This is the final step where the administrator validates and deploys the change set in the destination org. The administrator needs to have permission to deploy change sets and resolve any deployment errors or warnings.

The correct way for an administrator to allow an org to publish a change set to another org is to open Deployment Settings in the target org, select the environments to allow publishing from and move them to the Enabled list. This creates a deployment connection between the source org and the target org, which allows the source org to upload change sets to the target org.

Two likely causes that could make the second submission of the same JSON payload fail are:

• The payment data must be updated. The payment data in the JSON payload contains information such as the payment method, amount, and authorization code. If the same payment data is used for the second order, it may cause a duplicate payment error or an invalid authorization error.
• The Order Reference Number must be updated. The Order Reference Number is a unique identifier for each order that is generated by the external system and sent in the JSON payload. If the same Order Reference Number is used for the second order, it may cause a duplicate order error or an invalid order error.

The best way for an administrator to synchronize licenses from the production org when preparing a sandbox for development is to run the Match Production Licenses to Sandbox without a Refresh tool in Setup. This tool allows administrators to match their sandbox licenses with their production licenses without refreshing their sandbox. This way, the administrator can ensure that the sandbox has the same number and type of licenses as the production org, and avoid any license-related issues when developing or testing in the sandbox.

Three things that the administrator can do to get more details for debugging when encountering an unhandled fault error are:

• Create a fault connector. A fault connector is a special type of connector that handles errors that occur in a flow element, such as an assignment, a loop, or an action. A fault connector can route the flow to another element or end the flow with an error message.
• Add a Display Text component which includes {! SFIow.FaultMessage}. A Display Text component is a screen component that displays text on a screen element in a flow. The {! SFIow.FaultMessage} is a system variable that contains information about the error that occurred in the flow, such as the element name, error type, and error message.
• Create an error connector. An error connector is a special type of connector that handles errors that occur in a screen element, such as invalid user input or required fields being left blank. An error connector can route the flow to another screen element or end the flow with an error message.

The best way for the administrator to meet this requirement is to modify the compact layout on the Credit Memo object. A Credit Memo is a record that represents a refund or credit issued to a customer for an order or part of an order. A Credit Memo has various fields and related lists that display information such as the credit amount, status, reason, etc. A compact layout is a type of layout that determines which fields appear in the highlights panel at the top of a record page in Lightning Experience or Salesforce mobile app. The administrator can use the Object Manager to modify the compact layout on the Credit Memo object and add the Total Amount field to the compact layout. This way, the sales team can see the Total Amount field in the highlights panel at the top of the Credit Memo record page.

Once the administrator has activated the integration between B2C Commerce and Order Management, orders being placed by customers will be sent to Order Management if the order status is set to Active or New. These are the two order statuses that indicate that an order has been created or confirmed by a customer, and that it needs to be processed by OrderManagement.
