First-Expired-First-Out (FEFO) is a sorting method that ensures that the oldest items, those with the earliest expiration dates, are picked first.
This functionality only works when the following criteria are met:
-
The item must have a serial/lot number.
-
On the item’s item tracking code setup, the SN-Specific Warehouse Tracking field or the Lot-Specific Warehouse Tracking field must be selected.
-
The item must be posted to inventory with an expiration date.
-
On the location card, the Require Pick check box must be selected.
-
On the location card, the Pick According to FEFO check box must be selected.
-
On the location card, the Bin Mandatory check box must be selected.
When all the criteria are met, then serial/lot-numbered items to be picked are sorted with the oldest first in all picks and movements, except for items that use SN-specific or lot-specific tracking.

| If some serial/lot-numbered items use specific tracking, then those are respected first and under them, the remaining, non-specific, serial/lot numbers are listed according to FEFO. |
If two serial/lot-numbered items have the same expiration date, then the program selects the item with the lowest serial or lot number. If the serial or lot numbers are the same, then the program selects the item that was registered first.
