What must happen before using the mobile device to receive a purchase order?

The correct answer is that the purchase order must be created before using the mobile device to receive a purchase order. In the context of supply chain management and Dynamics 365, a purchase order is the official request made to a vendor to supply goods or services. Before receiving inventory through mobile devices or any means, the purchase order serves as the foundational document that outlines what has been ordered, the quantities, and agreed prices.

Creating the purchase order ensures that there is a record of the transaction, which facilitates inventory management upon the arrival of items. This foundational step sets the stage for all subsequent actions related to the receipt of goods, such as verifying purchase orders against incoming shipments, managing stock levels, and updating records.

While it may seem logical that the delivery must arrive at the dock first, without the prior creation of a purchase order, there would be no authorization or record of what is expected to be delivered. Thus, the order must be established before any receiving activities can take place.
