In our warehouse, stock is available in reserve storage types, but the picking bin becomes empty or falls below the minimum quantity. The expected replenishment warehouse task is not created, which can affect outbound picking.

I would like to understand the complete replenishment process and the required configuration.

Please help with the following points:

• What is replenishment in SAP EWM and why is it used?
• What is the difference between planned replenishment, automatic replenishment, order-related replenishment, and direct replenishment?
• What master data is required for replenishment, including fixed bins, minimum quantity, maximum quantity, and replenishment quantity?
• How can we configure a storage type for replenishment?
• How does SAP EWM determine the source storage type and destination picking bin?
• How do warehouse process type, storage type search sequence, and stock removal rule affect replenishment?
• Why is replenishment not triggered even when the picking bin is below the minimum quantity?
• Can open warehouse tasks, blocked stock, stock type, or capacity checks prevent replenishment task creation?
• How can we run planned replenishment manually and schedule it as a background job?
• Which transactions and /SCWM/MON nodes should be checked for replenishment errors?
• What are common configuration mistakes and real-time troubleshooting scenarios?

A step-by-step guide with SAP EWM configuration paths, transaction codes, practical examples, and troubleshooting tips would be very helpful.

Issue Description

• Stock level in picking bin falls below minimum quantity

• Replenishment process expected to trigger automatically

System Behavior

• No replenishment warehouse task created

• No error message displayed

• Inventory data appears correct

However, automatic replenishment is not triggered.

Questions

What are the common reasons why replenishment is not triggered automatically?

Which configuration settings control replenishment in SAP EWM?

How can this issue be diagnosed step-by-step in a real project?

Which transactions or monitors should be checked first?

Looking for practical troubleshooting guidance from real SAP EWM implementation experience.

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.
