WAREHOUSE MODERNISATION WITH SAP LES / TRM
The AL-KO Group restructured its entire distribution logistics from scratch. Part of this project included comprehensive upgrading work on the systems deployed within the shipping centre operated at its Kötz premises.
Alongside the conversion of the conveyor control system from SIEMENS S5 to SIMATIC S7, one key focus was the complete replacement of the outdated warehouse management system, including material flow control in the automated high-bay warehouse, with the SAP Logistics Execution System (SAP LES) plus SAP TRM (SAP Task and Resource Management).
Thanks to the direct integration of SAP LES/TRM (Logistics Execution System/Task and Resource Management) with the underlying SIEMENS control systems, AL-KO dispensed with the material flow controller layer to deploy a two-tier architecture: SAP-PLC.
The AL-KO Group comprises three business segments: Automotive Technology, Garden & Hobby and Air Conditioning. Overall, the group employs around 4,000 people in over 40 companies worldwide.
The Group's largest segment (Automotive Technology) operates from 31 locations and currently employs a workforce of around 2,650.
With a wide range of chassis and component solutions involving the AMC Chassis, trailers, caravans and automotive, AL-KO is a leading international supplier and innovation leader.
At that time, ALOIS KOBLER GmbH began planning the restructuring of its entire distribution logistics. Part of this project included comprehensive upgrading work on the systems deployed within the shipping centre operated at its Kötz head office.
The legacy warehouse management system, "LLS", developed specifically for AL-KO, was replaced in its entirety by the SAP Logistics Execution System (SAP LES), since the existing WMS was incapable of offering adequate options in terms of extensibility, maintenance and backwards compatibility.
Accordingly, AL-KO decided to adopt a future-proof logistics platform based on the SAP software suite. With SAP LES (SAP Logistics Execution System) and SAP TRM (SAP Task and Resource Management), AL-KO now has all of its warehouse logistics processes mapped to a single system, and uses SAP to manage both manual storage and the fully-automated pallet warehouse.
AL-KO now sees itself as superbly equipped to face the future, and can also roll out the SAP LES/TRM (Logistics Execution System/Task and Resource Management) to other sites if necessary.
