Most large supply chains don’t run on a single system. They rely on a combination of platforms.
SAP manages:
Core business processes
Data and transactions
End-to-end visibility
While solutions like Manhattan Associates focus on:
Advanced warehouse execution
Order fulfilment
Supply chain optimisation
That’s where the concept of SAP Manhattan integration comes in. It’s about bringing these systems together through seamless integration, so planning, inventory and execution work as one with seamless data flow. If you’re reviewing your supply chain architecture or integration strategy, the goal is simple: Connect SAP with best-in-class execution systems. Coordinate the entire supply chain. Make operations efficient and visible.
There is no single product called “SAP Manhattan”. Instead, the term refers to: The integration between SAP systems and Manhattan Associates solutions.
This typically includes:
SAP S/4HANA (ERP)
SAP supply chain systems (SAP EWM, TM, IBP)
Manhattan Warehouse Management (WMS)
Manhattan Order Management (OMS)
That gives deep integration between SAP EWM and SAP S/4HANA across core supply chain processes.
Together, they create a hybrid supply chain architecture. SAP EWM also supports flexible deployment options, including on-premise, cloud, and hybrid models.
SAP provides:
Core transaction processing
Financial and operational data
Integrated enterprise processes
Manhattan provides:
Advanced warehouse capabilities
Sophisticated order fulfillment logic
High-volume execution performance
Organisations combine them when:
SAP alone does not meet complex warehouse needs
They want best-of-breed execution on top of ERP
Supply chain processes require advanced optimization across complex warehouse operations
There is a clear division of responsibilities.
ERP system of record
Manages orders, inventory management and finance
Provides data consistency
SAP EWM also provides granular inventory management at the storage bin level.
Execution platform with Manhattan Active
Manages warehouse tasks and fulfilment
Optimises operational performance
The relationship is SAP is decision and control. Manhattan Active Warehouse Management is execution and optimization.
It runs on cloud infrastructure with a cloud-native microservices architecture.
It also receives frequent updates every 90 days, with continuous updates that deliver new features.
Integration is critical. SAP EWM can connect not only to SAP applications but also to other software, including Oracle and microsoft dynamics.
Without it:
Systems operate in silos
Data becomes inconsistent
Processes break down
Integrations commonly rely on qRFC, web services, middleware, and APIs to support reliable data exchange.
The result:
SAP sends:
Sales orders
Purchase orders
Inventory data
Master data
Manhattan returns:
Inventory updates
Order fulfilment status
Shipping confirmations
This is usually handled through:
SAP BTP (Business Technology Platform)
Middleware (e.g. integration suites, APIs) connecting warehouse platforms with transportation management systems and other management systems
Event-driven architecture
The result:
Seamless data flow
Aligned processes
Consistent system behaviour
One of the most common use cases is warehouse management integration, where a warehouse management system WMS organizes, tracks, and optimizes warehouse operations before connecting with SAP and Manhattan. Its key features include real-time visibility, control of stock movements, and support for order fulfillment.
Complex, high-volume warehouses and large distribution centers
Advanced picking and fulfilment needs
Automation and robotics integration
Manhattan WMS is often chosen where productivity depends on automation and efficient handling of repetitive tasks.
SAP manages inventory ownership and tracks stock levels
Manhattan manages physical warehouse execution, including labor management
SAP receives an order
Order is sent to Manhattan
Manhattan executes picking and packing
Shipping data is returned to SAP
Once shipments are ready, this integration also supports seamless coordination with transportation management.
This ensures:
Operational efficiency
Data accuracy
End-to-end process visibility
Integration is also common in order fulfilment.
Order creation
Billing and financial processing
Order routing
Fulfilment optimisation, including a labor management module to improve execution performance
Delivery execution
This is particularly useful in:
Omnichannel retail
High-volume distribution environments
In a real-world scenario:
A customer order is created in SAP
Order is passed to Manhattan OMS/WMS
Manhattan determines fulfilment location
Warehouse executes the order
Shipment is confirmed back in SAP
This creates:
Faster fulfilment
Better customer experience
Real-time visibility
When implemented properly, integration delivers:
SAP for core ERP
Manhattan for advanced execution
Faster warehouse operations
Optimised fulfilment processes
Real-time tracking across systems
Supports large and complex supply chains, making it a fit for large enterprises with broader operational scale and more advanced requirements
Ability to combine multiple specialised tools
The result a more advanced and responsive supply chain.
Organisations often face:
Multiple systems to connect
Data mapping challenges
Inventory or order data not aligned
Systems not reflecting real workflows
Process disruptions can also stem from equipment failures when systems and warehouse automation are not coordinated.
Managing multiple platforms: Maintenance gets harder when teams balance SAP EWM deployment options across on-premise, cloud, and hybrid environments, with security also shaping those choices and older setups often bringing costly upgrades.
These challenges require strong integration design and governance.
Even well-integrated systems evolve.
Over time:
New processes are introduced
Volumes increase
Systems are extended
Without control:
Integration becomes fragile
Data becomes inconsistent
Efficiency declines
Integration must be continuously managed.
Application Management Services (AMS) support:
Integration monitoring
Issue resolution
Data synchronisation
Performance optimisation, including ongoing tuning of the labor management module
AMS ensures:
Systems remain aligned
Data stays consistent
Operations continue smoothly
SAP consultancy helps organisations:
Design integration architecture
Align SAP and Manhattan processes
Simplify complex system landscapes
Improve performance
This ensures:
Integration delivers value
Systems remain manageable
Modern landscapes often include:
SAP S/4HANA for ERP
Manhattan Active Warehouse Management for execution, built on cloud infrastructure with a cloud-native microservices architecture, plus continuous updates every 90 days and new features
SAP BTP for integration
Analytics platforms for reporting
This creates:
A hybrid supply chain ecosystem
Real-time operational visibility
Advanced execution capability
When it’s working well:
Systems are seamlessly integrated
Inventory is accurate in real time
Orders are fulfilled efficiently
Processes are aligned end to end
Data is consistent across platforms
The result is a connected supply chain, not disconnected systems.
