The Inventory Pick process supports the pick and shipment process based on an inventory pick document, optionally with or without the use of bins. In Microsoft Dynamics 365 Business Central, a pick document is generated in advance for one of the following:
Purchase return order
Sales order
Transfer order, outbound
Production consumption
This process has a sequential variant, please see link below.
Splitting pick document lines and posting of the pick document as receipt to the related order is integrated in the mobile process.
