Wave planning functionality contains the logic for pick-by-level algorithms; therefore, when picking for waves, you must assign pick-by-level algorithms in Algorithm Assignment Maintenance (4.6.9). For example, use a pick-by-level-by-date algorithm to pick in all areas for items by the most recent date first. If you do not use a pick-by-level algorithm, warehouse staff can pick in the wrong areas during wave release and replenishment. This is because only pick-by-level algorithms consider full pallet areas.
