Enable Picking Items by FEFO

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 Warehouse Tracking field or the Lot Warehouse Tracking field must be selected.
  • The item must be posted to inventory with an expiration date.
  • On the location, the Require Pick, Pick According to FEFO, and Bin Mandatory toggles must be turned on.

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 or 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 or lot-numbered items have the same expiration date, then the application selects the item with the lowest serial or lot number.

When picking serial or lot-numbered items in locations set up for directed put-away and pick, only quantities on bins of type Pick are picked according to FEFO.

To enable movements according to FEFO, leave the From Bin field empty on the Inventory Movement page or the Movement Worksheet pages.

If the Strict Expiration Posting field is selected on the Item Tracking Code Card, only items that are not expired will be included in the pick, and the lines are sorted according to the FEFO principle.
