First-Expired-First-Out (FEFO) is a method for selecting which items to pick first from inventory, by which the program prioritizes items with the earliest expiration dates to be picked first.
In order for FEFO to work in the program the location and items must meet the following criteria:
The Pick According to FEFO field in the location card must contain a check mark. For locations that do not require pick, this field does not affect how items are selected for shipment.
The item tracking code for the item must be set up for serial-number-specific or lot-specific warehouse tracking.
The item entries must be registered and posted with expiration dates.
When all of these criteria are met, the program creates picks according to FEFO in pick and movement documents only when the source document line does not already contain item tracking information as to which serial or lot number should be used. If only part of the quantity of the line is defined with specific lot or serial numbers, the program uses FEFO to define the remaining quantity to be picked.
When picking by FEFO, the program selects available items that expire first and the result is a temporary item tracking list based on expiration date. If two items have the same expiration date, then the program selects the item with the lowest lot or serial number. If the lot or serial numbers are the same, then the program selects the item that was registered first. The criteria for selecting a pick bin such as Bin Ranking and Break Bulk is applied to this temporary FEFO item tracking list.
When picking serial/lot-numbered items in locations set up for directed put-away and pick, only quantities on bins of type Pick are picked by FEFO.
To create movements according to FEFO, leave the From Bin empty in the Movement Worksheet.
