Raw materials should be arranged in a manner that allows for first in–first out (FIFO) or first expired–first out (FEFO) stock rotation. When raw materials are moved to staging for production, a best practice would be to record the lot codes and quantity moved so that all locations of the lot can be tracked. This record would be a KDE.
