Wave Replenishment
When you know the items needed for each order, you can ensure that stock moves from the reserve area to the picking area before the picking takes place.
Wave replenishment typically includes the following three steps; however, depending on the setup, you may not use all steps:
Step 1: Full-pallet picking
Step 2: Box picking from the reserve area
Step 3: Picking area replenishment
Wave replenishment is not mandatory. If your warehouse does not have a dedicated picking area and all stock is randomly distributed in the warehouse, replenishment is usually not required.
