Diagnosing orders and order summaries that are not created
Key Takeaway
When an order or order summary isn't created, review the Checkout API responses for failures, then check "Setup > Process Exceptions" for recent exceptions.
In B2B Commerce, an order and its order summary are created from the buyer's cart at the end of checkout. In newer LWR stores, much of that work runs in the background after the buyer clicks "Place Order", so an order can fail without the buyer seeing it. To diagnose a missing order, you check the Checkout API responses, find concurrent cart changes, and review the process exceptions that the store creates when background order creation fails.
Why orders fail in the background
B2B stores created with the LWR template in Spring '23 or later process orders asynchronously. Asynchronous processing improves store performance, but an order can fail in the background. A failed order raises a PlaceOrderFailed exception, which is converted into a process exception record.
