In today's competitive supply chain landscape, operational efficiency and inventory accuracy are crucial to meeting customer expectations and reducing fulfillment costs. Automatic Replenishment in SAP EWM is a strategic tool that helps businesses maintain seamless warehouse operations by ensuring that picking locations are consistently stocked without manual intervention. By automating the movement of goods from reserve areas to fixed picking bins based on real-time stock levels, businesses can prevent order delays, optimize labor utilization, and reduce stockouts. In this blog, we’ll explore how automatic replenishment supports warehouse efficiency and demonstrates its functionality through a practical test scenario.

Let’s dive into the key configuration steps that make this process work effortlessly behind the scenes.
Configuration:
1. Activate Replenishment strategies in storage type
Path: SIMG>SCM EWM> EWM>Internal warehouse process> Replenish Control> Activate Replenishment strategies in storage type |

2. Maintain Document types and item types for warehouse request
Path: SIMG>SCM EWM> EWM>Internal warehouse process> Replenish Control> Maintain Document/item Categories for replenishment |

3. Assign Fixed Bins to the products

4. Stock Removal Strategies

Test Case:
In this test scenario, we will walk through a practical example to validate how Automatic Replenishment works in SAP EWM. The goal is to demonstrate that a Warehouse Task is automatically created when the stock in a bin drop below the predefined minimum quantity threshold.
We’ll simulate a real-life outbound process, starting from the creation of a Sales Order, triggering a pick from fixed bins, and observing how the system handles replenishment post-picking. Verify that the system automatically triggers replenishment when the stock in a fixed bin falls below the minimum quantity after a picking confirmation.
Pre-requisites:
1. Ensure Sufficient Stock is Maintained in the Reserve Area
Before testing replenishment, verify that adequate stock is available in the Reserve Area (HLR1). This stock will be used by the system to automatically replenish the Fixed Bin once the stock level falls below the defined minimum threshold. The replenishment warehouse task will move stock from the reserve area to the fixed bin to ensure seamless picking operations.

2. Ensure Sufficient Stock is Available for Order Picking
Verify that enough stock is available in the Fixed Bin to fulfill the outbound delivery. Once the picking is executed and confirmed, the system checks if the remaining quantity in the bin has fallen below the configured minimum quantity. If so, the follow-up replenishment process is automatically triggered, creating a warehouse task to replenish the fixed bin from the reserve area ensuring readiness for future picking demands.
3. Stock Removal Strategies are Preconfigured for Order Picking
As a prerequisite, ensure that appropriate Stock Removal Strategies are already configured in the system. These strategies determine how the system selects stock from storage bins during the picking process for outbound deliveries. Having this in place ensures that the system can efficiently identify and pick stock from the correct bins when processing the sales order.
Create a Sales Order (T-Code: VA01)
Sales Order is created with a quantity of 26 units. Each fixed bin holds 10 units, and the minimum quantity is configured as 5 units (as shown in Step 3). After the picking process, we expect the system to identify that the stock has dropped below the minimum threshold and automatically trigger a replenishment task from the reserve area.
Create an Outbound Delivery in S/4HANA and Distribute to EWM (T-Code: VL01N)
Generate the outbound delivery based on the sales order and distribute it to the EWM system.
Process the Outbound Delivery Order in EWM (T-Code: /N/SCWM/PRDO)
Access the outbound delivery order and create the picking warehouse tasks.

Create Warehouse Task:
Outbound Delivery > Follow-on Functions > Warehouse Task

Three Warehouse Tasks have been Successfully Created for Picking. As expected, the system generated three warehouse tasks one for each fixed bin, each containing 10 units, to fulfill the 26-unit Sales Order. Upon confirmation of these tasks, the stock level in each bin is evaluated. Since the remaining quantity falls below the defined minimum threshold, the system is expected to automatically trigger three replenishment tasks from the reserve area.

Let’s now verify these replenishment tasks in the Warehouse Monitor. à Filter with Open Warehouse Task and Whse Process Type - 3010


Immediate Replenishment tasks have been automatically Created. The system has instantly generated replenishment tasks following the confirmation of picking tasks. The automatic creation of replenishment warehouse tasks is a result of the key configuration settings completed earlier such as activating automatic replenishment, defining the appropriate process type, and setting up effective stock removal strategies (as outlined in Steps 1, 4, and 5). These configurations work together to ensure seamless replenishment when fixed bin stock falls below the minimum threshold.
Before proceeding with the confirmation of these replenishment tasks, let’s first review the current stock levels in the fixed bins for the relevant products. This will help us validate that the system correctly identified the stock falling below the minimum quantity threshold and responded as expected.

Stock Status Before Replenishment Confirmation
One bin shows 4 units remaining, while the other two bins have disappeared from available stock, likely due to full depletion. Let’s confirm the replenishment tasks and verify the updated stock levels in the fixed bins.

Post Replenishment Task Confirmation
After confirming the replenishment tasks, all fixed bins are fully restocked and now ready for picking in upcoming outbound processes, as illustrated in the image below.

This example demonstrates how Automatic Replenishment functions in SAP EWM. When stock levels in the picking area fall below the defined minimum quantity, the system proactively creates replenishment tasks to transfer stock from the reserve area to the fixed bins. This ensures that stock is consistently available for picking, supporting uninterrupted outbound operations and enhancing overall warehouse efficiency. It's a powerful feature that helps businesses maintain optimal stock levels and streamline their fulfillment processes.
