High Scale Orders and order ingestion troubleshooting
Key Takeaway
With High Scale Orders, each Order is built from its OrderSummary, so only fields that exist on OrderSummary can carry over to the Order.
High Scale Orders is a B2B Commerce feature for handling high order volume at checkout in LWR stores. The feature changes how orders are created. An OrderSummary comes first, then the Order, and the Automated Process user creates both instead of the shopper. So developers need to finish its setup, adjust Apex and flows to fit it, and know where to look when orders don't appear.
Which stores use High Scale Orders
Starting in Summer '24, High Scale Orders is on by default at checkout for new B2B stores created with the LWR template. When you set up one of these stores with the Commerce Setup Assistant, high-scale order ingestion (HSOI) is enabled by default. B2B Commerce Aura stores don't support High Scale Orders.
