System Activity
Automatic Replenishment

3. Purpose
You use this warehouse process to fill up a picking area in accordance with the demand for products that you pick in this area. In this automatic replenishment process, you use warehouse orders (WOs) to execute replenishment. The system creates replenishment WOs in the background when you confirm a pick-WO, and the stock in the source bin falls below a predefined threshold. The system calculates the replenishment quantity in accordance with the maximum and minimum quantity maintained for the product in the product master.

4. Prerequisites You have integrated SAP EWM with SAP ERP.
You have configured the warehouse structure and master data.
You have configured your systems for this process.
You have open WOs from the Outbound Process Using Pick-HUs as Shipping HUs that decrease the stock below the threshold of replenishment during the confirmation.

5. Process Step Create replenishment warehouse orders (SAP EWM)
When a warehouse worker picks goods for an outbound process and confirms the pick-WO, the system determines in the background if a replenishment of the source bin is necessary. It calculates the replenishment quantity in accordance with the maximum and minimum quantity maintained for the product in the product master. The system creates replenishment warehouse tasks (WT) and warehouse orders (WO) when the stock is less than the minimum quantity. The system rounds down the replenishment quantity to a multiple of the minimum replenishment quantity. The replenishment WO is automatically assigned to a high priority queue.
In addition to the automatic replenishment, a background job regularly runs to trigger the replenishment of new products not stored yet in the picking area.

6. Process Step Replenish the goods (SAP EWM) – Step 1
A warehouse worker takes a vehicle (for example a fork lift) and logs on as a resource that is assigned to the high priority queue. The system guides the warehouse worker to the source bin of the first replenishment WT. The warehouse worker picks the required quantity of the product and puts the product onto his or her vehicle. He or she scans the source bin for verification purposes and enters the quantity. After all fields on the source screen have been verified, the warehouse worker is prompted to take the picked goods to the destination bin. When the worker arrives at the destination bin, he or she scans the destination bin for verification purposes again and confirms the replenishment WT in the system.

7. Process Step Replenish the goods (SAP EWM) – Step 2
If the warehouse worker finds a quantity smaller than the requested quantity in the storage bin, he or she enters an exception code, and records the quantity difference in the WT by entering the quantity he or she has actually picked. With the confirmation, the system reduces the stock on the current bin by the difference quantity. If necessary a new replenishment WT is created by the regular background job described in step 1.
When the last carton of a pallet is picked from the source bin, the empty pallet remains at the source bin and is removed during the putaway of a new pallet onto the bin.
