Configuration

Configure Order Split in Magento Admin:

Stores >Configuration > MageB2B > Order Split

1. General Settings

• Enable Order Split: Turn the extension on.
• Vendor Product Attribute: Choose a select or multiselect attribute that represents the vendor.
• Behavior When Vendor Is Missing: Block checkout, keep one order, or use an empty vendor group.
• Allowed Payment Methods: Split orders for listed methods. If this list is empty, all payment methods are treated as allowed.
• Behavior for Disallowed Payment: Block checkout or keep a single order.
• Behavior When Shipping Method Is Missing: Choose whether checkout is blocked or falls back to a single order if a split shipping method is unavailable.
• Checkout Split Notice: Optionally show a checkout notice that split order placement rules are active.
• Checkout Split Notice Text / Payment Method Visibility: Configure notice text and how payment options are shown when split rules apply.

2. Inventory (MSI)

• Use MSI Source Selection: Enable if you want splits by warehouse/source.
• Source Selection Algorithm: Use the default or a custom algorithm.
• Behavior When MSI Is Disabled: Split by vendor only, keep a single order, or block checkout.
• Behavior When Source Is Missing: Block, split by vendor only, or keep a single order.

3. Order Numbering

• Numbering Mode: Standard or Base ID with suffix.
• Base Suffix Format: Use {base} and {n} (example: {base}-{n}).
• Start Index / Max Attempts: Control suffix sequence and conflicts.

4. Totals Handling

Choose how totals are handled across split orders:

• Discount Split Mode
• Shipping Split Mode
• Tax Split Mode

All three modes must use the same strategy (Proportional or Recalculate). Mixed mode combinations are not supported and will block order placement.
