The Serialized flag is used to identify Inventory items for which Serial Number tracking is required.
If the Serialized field is enabled, Keystroke requires the entry or selection of a Serial Number whenever the item is bought or sold.
When a serialized item is sold: Enter a serial number or select one from the list.
When a serialized item is received: Enter the item's serial number to place it on the list.
