A technician repairing unfamiliar equipment may need details from an earlier visit before deciding what to check next. The dispatcher may know who has worked on the asset, yet that knowledge sits in a colleague’s inbox or a separate system. Meanwhile, service managers need a reliable view of assignments without asking every engineer for an update. These small gaps interrupt routine work and leave field teams switching between applications to find information they need.

The OPUS Extension Suite comprises 11 SAP FSM Extensions that connect SAP Field Service Management with the tools service teams use every day. Swiss consulting and technology firm OPUSm AG offers extensions for collaboration, calendar synchronisation, remote assistance and connections to other enterprise systems. Each addresses a defined workflow rather than replacing the core field service platform. For service leaders, the practical question is which missing connection causes the most friction and whether an existing extension can address it without bespoke development.

The Microsoft Teams integration lets an engineer open Teams from the SAP FSM mobile app and contact a colleague who knows the equipment. The connection also gives access to the asset’s service history. OPUS InviteOut sends service assignments to Outlook, while OPUS InviteIn transfers Outlook appointments to the planning board as reservations. SightCall brings live video and augmented reality into remote service sessions. These tools address different moments in a job, from checking past repairs to resolving a fault without sending another technician.

The technical fit matters as much as the feature itself. OPUSm AG handles requirements engineering, solution design and ERP integration, then carries the work through key-user training, go-live assistance and ongoing support. Its ERP connectors link SAP FSM with platforms such as Microsoft Dynamics, Abacus and SAP Business One, as well as document management and help desk systems.

For Heads of Service and SAP Managers, the first step is to pinpoint where staff leave SAP FSM to find information, check calendars or contact a specialist. That evidence can guide a focused discussion about which extension fits the workflow and whether integration work is needed. OPUSm AG’s consulting team can review the requirement against its existing portfolio.
