Lot products
In SA Administrator Options-Documents-Sales Orders-Entry Settings, the Force Lot/Serial Input option must be selected. This setting enables you assign lot numbers from Distribution SX.e when you enter the order. Specify only one lot per line. Otherwise, the lot is not released to TWL for suggested picking.
The first available lot is found by TWL based on the assigned location type that contains the largest quantity of available stock. If the location type is not specified, lots are selected alphabetically. When the product has an expiration date, that date is checked by TWL. This validation ensures that date is greater than the date you drop the order.
