The Order Splits grid links every group to its child Magento orders. It records the base number, customer, order count, combined total and child order numbers. Order comments add vendor and source context to the individual records.
Use this view to answer which orders came from one checkout. It is not a financial audit log and does not replace payment-provider, tax or warehouse records.
If orders are temporarily missing from the group, check registry recovery before creating manual links or duplicate orders.
