Final answer:
The document used to authorize the movement of goods from a warehouse to shipping is the Bill of lading.
Step-by-step explanation:
The document used when filling a sales order to authorize the movement of goods from a warehouse to shipping is the Bill of lading. It is a legal document issued by a carrier or shipping company that provides details about the shipment, including the description of the goods, quantity, weight, and destination.
The Bill of lading serves as a receipt of shipment, evidence of the contract of carriage, and a document of title. It is important for both parties involved in the transaction, as it ensures that the goods are properly accounted for and delivered to the correct location.
