MSI Source Routing

When MSI is enabled, Order Split can also group items by warehouse/source.

How It Works

• Magento's MSI source selection algorithm is used to resolve a source for item groups.
• When a single source can be resolved for a group, orders can be split so each warehouse ships its own items.

MSI Fallbacks

If MSI is disabled or no source can be determined, you can decide whether to:

• Split by vendor only
• Keep a single order
• Block checkout

Per-warehouse splitting depends on successful source resolution. If resolution is not possible, configured fallback behavior applies.
