Auto Guided Vehicle or Autonomous Logistics Vehicle
AGV/ALV Integration with SAP Extended Warehouse Management (EWM) refers to connecting Automated Guided Vehicles (AGV) or Autonomous Logistics Vehicles (ALV) with SAP warehouse processes so that material movement is automated and controlled through SAP.
Below is a structured explanation.
1. What are AGV / ALV in Warehousing
AGV (Automated Guided Vehicle) – Driverless vehicle that follows predefined paths using sensors, magnets, or lasers to move pallets or bins.
ALV (Autonomous Logistics Vehicle) – More advanced than AGV; can navigate dynamically using AI, SLAM mapping, and obstacle detection.
These vehicles automate internal warehouse transport.
2. Role of SAP EWM in Automation
SAP Extended Warehouse Management manages:
Warehouse tasks
Storage bins
Material movement
Resource management
Integration with automation equipment
EWM sends warehouse tasks to automation systems, including AGV fleets.
3. Integration Architecture
Typical architecture:
SAP S/4HANA / SAP EWM
│
│ (Warehouse Task / Telegram / API)
▼
Warehouse Control System (WCS)
│
│ (Vehicle Commands)
▼
AGV Fleet Management System
│
▼
AGV / ALV VehiclesKey Layer: WCS
The Warehouse Control System (WCS) acts as middleware between EWM and the AGV system.
4. Integration Methods
1. SAP EWM MFS (Material Flow System)
SAP EWM Material Flow System is used to control automated equipment directly.
Capabilities:
Communication with PLCs
Telegram-based messaging
Real-time equipment control
For AGV:
EWM sends warehouse tasks
MFS converts tasks into telegram commands
AGV system executes movement.
2. WCS Middleware Integration
Common in modern warehouses.
Integration technologies:
REST APIs
IDoc
RFC
Message queues
SAP Plant Connectivity (PCo)
Typical flow:
Warehouse Task created in EWM
Sent to WCS
WCS assigns AGV
AGV performs movement
Confirmation sent back to EWM
3. SAP EWM Resource Management
EWM treats AGVs as resources.
Functions include:
Queue management
Task prioritization
Resource allocation
Status tracking
5. Typical Process Flow
Example: Pallet movement from production to storage
Production confirms finished pallet.
EWM creates Warehouse Task (WT).
WT sent to WCS/AGV Fleet Manager.
AGV receives command:
Pickup location
Destination bin
AGV moves pallet.
AGV sends completion message.
EWM confirms WT.
6. Common Use Cases
AGV integration is used for:
Pallet transport
Production line feeding
Goods receipt transport
Automated storage system feeding
Cross-docking movement
Industries:
Automotive
FMCG
Pharmaceuticals
Manufacturing
7. Major Benefits
8. Key SAP Objects Used
Important EWM objects:
Warehouse Tasks (WT)
Resources
Communication channels
Queues
Storage bins
Telegram messages (MFS)
9. Popular AGV Vendors Integrated with SAP
Examples:
Daifuku
SSI Schaefer
Dematic
Toyota Material Handling
These vendors provide AGV fleet management systems integrated with SAP EWM.
