There are two ways to deal with the situation:
1) If the parcel has been sent out and the invoice for the outbound order has been completed, a return order may be issued. The return order method can be “add back to stock” After receipt of the return order, the product will be added back to the inventory.
2) If the package has not been sent, the outbound order can be canceled in the “to ship” state and the quantity of the outbound order will be updated to the inventory automatically. The inventory of the SKU involved in the outbound order will be shown in the “Cancellation Storage ” section, where you can transfer the inventory.
