Warehouse Fulfillment - Invoicing/Order Completion

Once the inventory that is required for the orders to be shipped out of the warehouse is received into inventory, the system allocates the available inventory to the orders.

Picklists are then generated for the orders which have allocated lines with schedule dates that are within the current Picklist Window, and which are not on hold for any reason.

The picklists specify the items and quantities, to be picked for the order and the bins that the items should be picked from.  Once the goods for the order have been picked, the picklist is used to invoice or complete the order and the goods are sent out to the customer.
