What SAP MFS is
Material flow controlled directly from EWM
SAP MFS (Material Flow System) is a native part of SAP EWM that communicates directly with the control units (PLC) of automated warehouse equipment. This removes the separate middle layer (WCS) between the warehouse system and the machines.
In practice this means EWM doesn't just plan but also directly controls the movement of goods on conveyors, stacker cranes, or automated vehicles. One system, one set of data, one place to monitor the warehouse.
What MFS connects
The equipment EWM controls through MFS
MFS is open to various types of automation. The exact scope always depends on your equipment and supplier. These are the typical areas we work with.
Stacker cranes (AS/RS)
Automated put-away and retrieval in high-bay racking, controlled directly from EWM via MFS.
Conveyor systems
Routing goods along conveyors, splitting and merging flows according to the current warehouse tasks.
Robots and AGVs
Connecting mobile robots and automated guided vehicles to transport goods between warehouse zones.
Control units (PLC)
Direct telegram communication with equipment PLCs, without a separate WCS layer that would need to be maintained on its own.
Identification and scanning
Integrating scanners, readers, and weighing points into the automated flow for continuous checking and tracking.
Integration with EWM processes
Automation doesn't sit on the side. It ties into receiving, picking, and shipping run by standard EWM processes.
What automation brings
Why control equipment directly from SAP
The main advantage of MFS is that it removes a separate middle layer. Fewer systems means fewer places where something can break, and simpler maintenance.
Higher warehouse throughput
Automated equipment handles more movements than manual handling and works without breaks.
Fewer errors and fewer systems
Direct control from EWM without a WCS layer means one set of data and fewer places where a mismatch can arise.
Scalability
Automation can be expanded gradually. You add equipment and zones as your volume grows.
Operation without breaks
Automated zones can run outside shifts too, increasing throughput without a proportional increase in headcount.
Frequently asked questions
What's the difference between MFS and WCS?
A WCS (Warehouse Control System) is a separate layer between the warehouse system and the equipment. MFS fills that role directly inside SAP EWM, so you don't have to run and maintain another standalone system.
Do we need advanced EWM for MFS?
Yes, MFS is an advanced SAP EWM capability. If you're planning warehouse automation, that's one of the reasons to choose advanced EWM as your warehouse system.
What equipment can MFS work with?
MFS communicates with control units (PLCs) using standard telegrams, so it's open to various suppliers of conveyors, stacker cranes, and robots. We always verify the exact scope with you and your equipment supplier.
Can we roll out automation gradually?
Yes. It makes sense to start with a selected zone or process and expand the automation as volume grows and the first phase proves itself.
