Replenishment is the process of moving stock from bulk storage (reserve/storage bins) to picking areas (forward picking bins) so that enough stock is always available for picking.

Think of it like restocking supermarket shelves:

• Bulk storage = Warehouse backroom.

• Forward picking bins = Shelves for customers.

• Replenishment = Staff bringing items from the backroom to refill shelves.

Why is Replenishment Needed?

• Picking bins usually have limited space.

• If stock runs out, picking tasks cannot be executed.

• Replenishment ensures continuous availability of stock in picking areas.

Types of Replenishment in SAP EWM

1. Planned Replenishment

   • Triggered before picking bins are empty.

   • System checks minimum stock / reorder point.

   • Example: If forward bin requires 100 pcs min, and stock falls to 80 → replenishment triggered.

2. Automatic (or Demand-Driven) Replenishment

   • Triggered during picking if bin is empty or doesn’t have enough stock.

   • Example: Picker needs 20 pcs, bin has 5 pcs → system creates replenishment task automatically.

3. Manual Replenishment

   • User manually triggers replenishment based on operational needs.

   • Example: Supervisor sees low stock in a bin and creates replenishment task.

How Replenishment Works in EWM

1. System checks stock levels in forward picking bins.

2. If stock is below threshold, system creates a Warehouse Task (WT):

   • Source bin = Reserve/bulk storage.

   • Destination bin = Forward picking bin.

3. Operator confirms task via RF device or desktop.

4. Stock is moved and replenished.

Transactions / Tools for Replenishment

• /SCWM/REPL → Replenishment control.

• /SCWM/MON → Warehouse Monitor → Replenishment node.

• /SCWM/WT → Warehouse Task monitor (to check replenishment tasks).

• RF Transactions → Mobile execution of replenishment tasks.

Configuration (High-Level)

• Define replenishment control parameters (per storage type/bin).

• Set:

  • Minimum quantity.

  • Maximum quantity.

  • Replenishment quantity (how much to move).

• Assign control to storage type → so EWM knows when to trigger replenishment.

Example

• Forward bin capacity = 100 pcs.

• Minimum stock = 20 pcs.

• Current stock = 15 pcs.

• System automatically creates WT: Move 85 pcs from bulk storage to forward bin.
