The process of inspection and logistical follow-up can be integrated into two types of warehouse management system:
SAP Warehouse Management System (WMS) of the SAP Logistics Execution (LE) component
This means that goods movements and stock changes are managed in the warehouse at storage bin level using quants. Stock movements can be introduced with a transfer requirement or executed with a transfer order in the warehouse.
For more information, see Warehouse Management System (WMS).
Lean Warehouse Management
Here, inventory management takes place solely at storage location level. The system does not update the stock data at storage bin level using the quants.
For more information, see Warehouse Management with Lean WM.
The following is an example of the full integration of the SAP Warehouse Management System (WMS) into Advanced Returns Management
. The WMS comes into play at two points in the process: during returns document creation, and during inspection with a resulting logistical follow-up activity.
A returns order is created. The returned goods must be received into the plant for inspection, so the processing employee selects follow-up activity Receive into Plant
. The system creates a returns delivery. If a warehouse number is assigned to the combination of plant and storage location, the goods receipt cannot be posted until all warehouse management activities have been completed. A transfer order is therefore created for the inbound delivery. This results in the returned goods being moved from the interim storage bin to the specified destination storage bin. The system determines these from Customizing.
Once the transfer order is confirmed, the goods receipt is posted, and the system updates the stock available at the destination storage bin.
Note
Whether a transfer order is created and confirmed automatically or by a user depends on the settings made in Customizing for Warehouse Management
.
An example of a transfer order created for a returns delivery to execute the relevant goods movements is shown in the figure below:

The warehouse inspector examines the returned goods and assigns the appropriate inspection code, splitting the items where necessary.
The warehouse manager selects and confirms the appropriate follow-up activity for each item and its splits. When logistical follow-up is confirmed, the system creates a new transfer order to record the stock splits resulting from inspection in the warehouse management system. This transfer order is automatically confirmed as it does not result in any physical movement of stock.
An example of a transfer order created to record stock splits resulting from inspection is shown in the figure below:
Stock Changes for Split Item
Note
Items 20 and 30 are not included in this transfer order because they were not split and do not require stock changes.
Based on the selected follow-up activities, the system creates the relevant goods movements or outbound deliveries for each inspection item and inspection split item. Another transfer order is created to execute the associated goods movements. The system ensures that the correct stock is moved from the correct storage locations.
