Asset Repository Showdown: Why Business Network Asset Collaboration Leads the Way
Carlos Lemos, SAP Business Network Asset Collaboration marketing lead
When managing asset information, not all repositories are created equal. The difference between SAP Business Network Asset Collaboration (BNAC) and traditional CMMS (Computerized Maintenance Management Systems)/ERP repositories goes far beyond data storage — it’s about the future of asset collaboration in an interconnected world.
The Strategic Edge of BNAC
BNAC is purpose-built for today’s ecosystem-driven reality. Its power lies not just in storing asset data, but in enabling real-time, multi-party collaboration across the asset lifecycle - a critical advantage in industries where assets are commissioned by one party, operated by another, and maintained by a third.
What makes BNAC different - and better?
Ecosystem-Wide Visibility
BNAC operates as a neutral, cloud-native hub for asset data. OEMs, operators, and service providers can contribute to and access a single source of truth - whether it’s specifications, digital twins, or maintenance records.
Real-Time Collaboration Without Borders
Unlike static systems that update in silos, BNAC reflects changes instantly across all parties. This is indispensable during critical phases like commissioning, troubleshooting, or warranty claims.
Lifecycle-Centric Design
BNAC was designed to span the full operation and maintenance lifecycle of an asset — from handover, maintenance to retirement. It ensures that collaboration and context don’t end when the asset goes live — they evolve with it.
Faster Time-to-Value Across the Network
Because it’s cloud-based and shared, BNAC can be deployed quickly and scaled across a partner ecosystem, reducing coordination costs, system integrations and aligning all players.
BNAC isn’t just an asset repository. It’s a collaboration engine that turns asset data into a living, evolving asset narrative shared across stakeholders.
CMMS/ERP: Important, but Internally Focused
While CMMS and ERP systems (like SAP S/4HANA) remain essential for internal operational execution, their architecture is inherently inward-facing.
They excel at linking asset data to maintenance work orders, financial tracking, or inventory management — but within one organization’s four walls.
They offer detailed control and customization, but typically require manual updates or integration to connect externally.
Their role is essential in executing maintenance and financial processes, not in managing shared understanding across a supply chain.
Key Differences in Context
- Scope: BNAC is outward facing, connecting your organization with their teams and with external partners. A CMMS or ERP is inward-facing, focusing on your internal workflows and systems.
- Collaboration vs. Control: BNAC prioritizes multi-party collaboration. Prioritizing shared visibility. A CMMS or ERP prioritizes control and depth within your own domain, with collaboration typically limited to internal teams or manual data exchanges with partners.
- Deployment: BNAC’s cloud-based, network-driven approach makes it faster to deploy across an ecosystem. A CMMS or ERP often requires more setup (especially if on-premises) but integrates more tightly with your existing tech stack.
Best of Both: Integration, Not Duplication
Forward-thinking organizations are increasingly adopting a hybrid model. In practice, many businesses use both. BNAC can serve as central and collaborative front-end repository, syncing ecosystem data into a CMMS or ERP (like S/4HANA via SAP BTP) for internal processing. For instance, an operator might use BNAC to make available asset information globally. Or an asset owner might use BNAC to access an OEM’s commissioning docs, then feed that data into their ERP to manage the asset’s lifecycle internally. This hybrid model leverages BNAC’s external connectivity and the CMMS/ERP’s internal depth.
In summary:
- BNAC is used as the external-facing, collaborative repository to manage and enrich multi-party asset information.
- CMMS/ERP systems are driven by internal workflows and financial tracking keeping full control over asset data within the organization
The choice—or blend of the two—depends on whether your priority is uniting an external network or optimizing your internal operations.
Summary: Why BNAC Should Be Your Strategic Front-End
In essence, BNAC’s advantage lies in breaking down silos between organizations, fostering proactive collaboration, and providing a dynamic, shared repository that evolves with input from the entire ecosystem. It’s less about internal management and more about external alignment.
BNAC can serve as an extension to your CMMS or ERP system. It is not just an operational add-on, but the strategic front-end repository that makes your internal systems smarter, faster, and more connected — and your processes more agile and efficient.
