Legacy combined mode uses one combined order for payment and the parcel. Split payment/shipment mode uses a payment order for the fee and a separate shipment order for the parcel. Original orders preserve the original purchases. Never pack from the split-mode payment copy.
By default, originals are reconciled when the physical shipment is fulfilled. Auto-complete orders after payment is a separate existing setting that can close originals earlier. Do not change it just to print. Review Which order to fulfill before changing warehouse automation.
Use Addora packing slips to exclude billed portions from originals. Check Order tags for OMS when configuring another fulfillment tool.
