SUDenergie

How SUDenergie is powering ahead with SAP FSM

When a digital foundation starts to show cracks, it’s time for a renovation. For SUDenergie, a utility provider based in Luxembourg, that moment arrived when SAP announced it would discontinue support for Workmanager, their long-standing mobile field service tool. With dozens of technicians relying on it daily, the stakes were high.

SUDenergie turned to SQLI to implement a future-proof, cloud-based alternative. The result: a full-scale transformation using SAP Field Service Management (FSM) to streamline service planning, dispatching, and execution in the field. But this wasn’t just a replacement. It was a smart, phased leap toward digital excellence. 

The challenge of SUDenergie

Until recently, SUDenergie operated its service workflows using SAP ISU (ECC) in combination with Workmanager. With Workmanager support ending in 2024, they needed a new mobile solution, fast. The requirements were clear: 

  • Seamless integration with existing SAP ISU systems
  • An intuitive mobile experience for technicians
  • Room to grow and evolve the platform over time 

Beyond functionality, SUDenergie also aimed to improve how interventions were scheduled and managed, while keeping disruption to a minimum for planners and technicians alike. 

SQLI’s approach and solution

SQLI presented a stable, SAP-native solution from SAP FSM Mobile supported by FSM Planning Board and FSM Cloud Connector (via Proaxia). There is a set 7-stage process to the project with clear milestones and very little risk involved.

The seven phases of transformation

  1. Preparation: Kick-off meetings, planning and tooling configuration
  2. Blueprint: Fit-gap workshops to plan the mapping of generic FSM features onto SUDenergie requirements
  3. Realization: FSM and Proaxia connector configuration and required custom developments
  4. Integration testing: Ensure that all the processes integrate well with one another
  5. Acceptance testing: Testing the customer based on real-world usage scenarios
  6. Final preparation & go-live: Production deployment, data migration, and user training
  7. Hypercare: Extensive support after going live to ensure acceptance and stability 

 

FSM in action

SAP FSM Mobile gives technicians a user-friendly interface to execute their tasks. Features include:

  • Digital workflows using Smartforms
  • Barcode scanning for equipment
  • Material tracking, time logging, and on-site photo uploads

FSM Planning Board is the technical scheduler, aligning activities developed in SAP ISU with FSM Mobile. Semi-automatic planning functionality has been implemented for future scalability. FSM Cloud Connector and a single Message Broker manage real-time synchronization between systems to enable flawless operation across platforms.


Results and impact 

The project was already well down the line towards January 2025 Go-Live, with numerous significant milestones already reached: 

  • Technical and functional blueprint completed
  • Development and test environments running
  • Specific extensions (e.g. mobile to make service call, report generation using JasperSoft) in development 

SUDenergie is now set up for more agile, efficient, and technician-friendly service delivery, powered by a cloud-native platform that evolves with their business.
 

Our 3 key takeaways for success

  1. Think beyond replacement 
    SUDenergie’s goal wasn’t just to swap out a tool, but to modernize how services are delivered in the field. By embracing SAP FSM and planning for future use of its full dispatching capabilities, the foundation is now set for long-term agility. 
  2. Design with the technician in mind 
    The mobile experience was built around real usage needs—from offline access to guided workflows and barcode scanning. Field usability wasn’t a nice-to-have, it was central to the solution. 
  3. Co-create your blueprint 
    Close collaboration between SQLI and SUDenergie made sure that some operating needs were not just heard, but embedded in the system from day one. This co-creation approach simplified the blueprint process, made it faster, clearer, and more future-oriented.
