Which document primarily manages the picking process in warehouse management?

The outbound delivery order is pivotal for managing the picking process in warehouse management as it initiates the preparation of goods for shipment to customers. This document is generated after the sales order and contains vital information regarding the items to be picked, their quantities, and the destination.

When the outbound delivery order is created, it triggers specific warehouse management processes, including the selection of the appropriate storage locations, determination of picking strategies, and the execution of picking tasks. This ensures that the correct items are gathered to fulfill the customer's order efficiently.

In contrast, while a sales order indicates customer demand, it does not directly manage the logistics of picking. Stock transfers primarily deal with the movement of stock between different locations rather than fulfilling customer orders. A purchase order refers to procurement activities and is not involved in picking processes related to outbound deliveries. Thus, the outbound delivery order is uniquely suited for overseeing the picking process in the context of warehouse management.
