SAP Business Network Asset Collaboration: Master Data, Service Partners, and Digital Twins

When maintenance teams work with OEMs, EPCs, and service partners, traditional point-to-point interfaces quickly hit their limits. SAP EAM maps internal processes cleanly, but the flow of information often stops at the plant gate: manufacturers deliver PDFs instead of a digital twin, external partners work with Excel or paper, and every new integration creates additional effort.

SAP Business Network Asset Collaboration (BNAC) directly addresses this gap—acting as a collaborative extension of SAP integration between operators, manufacturers, and service providers.

Many companies have built individual integrations over time: EDI, file drops, portals, or email workflows. These setups work, but they have typical weaknesses:

• high integration effort for each new partner

• little transparency on master data, documents, and history

• limited scalability as the partner landscape grows

ERP or EAM systems work well internally – but without robust connectivity to manufacturers and service providers, the picture remains incomplete.

SAP Business Network solves this by having partners connect to the network once, while the integration to SAP S/4HANA or ERP remains standardized. Operators no longer have to build and maintain a patchwork of custom interfaces.

BNAC focuses on collaboration around assets, equipment, and spare parts. From a business perspective, three core building blocks stand out.

Central asset repository

A cloud-based directory consolidates assets from one or more ERP or EAM systems – including technical data, documentation, history, and manufacturer links. Operators gain a unified view of their asset structure, independent of source and format.

Collaborative asset definition (digital handover)

Instead of PDFs, the manufacturer delivers a digital twin: serial numbers, structure, documentation, certificates, and spare parts lists are provided via the network and updated when changes occur.

This creates a complete, well-structured data set that can be taken over into SAP EAM without manual cleanup.

Collaborative maintenance

Operators share notifications and work orders directly with service partners. External providers process activities, time, and materials in BNAC and send confirmations back – directly into the operator’s SAP system.

External teams no longer work “next to” ERP and EAM, but as an integrated part of the process.

For operators, this means: more consistent master data, fewer breaks in the process and data flow, and less manual rework. Manufacturers and service providers gain direct digital access to the operator – including opportunities for service business and spare parts management.

Enel: millions of assets in a central repository

Energy provider Enel manages millions of assets across countries and systems. With BNAC, a central repository was set up that:

• consolidates asset structures from SAP and non-SAP systems

• holds digital twins including documents and history

• cleanly supports internal handovers (e.g. from project team to operations)

The result: less effort for master-data handovers, higher data quality – and a reliable foundation for future SAP APM or AI scenarios.

LESER: digital handover of safety valves

Manufacturer LESER delivers safety valves with a digital identifier (e.g. QR code). During production, all relevant data is written into a digital twin, including:

• specifications and pressure ratings

• test and acceptance documentation

• spare parts lists according to VDI 2770

No paper binder arrives at the operator anymore. By scanning the identifier, the digital twin is retrieved from the network and integrated into SAP EAM. For brownfield plants, valves can be tagged and enriched retrospectively.

External service providers: collaborative maintenance with BNAC and mobile app

Today, many external technicians still work with PDFs, Excel, or phone calls. With BNAC, the process becomes much clearer:

• the operator shares notifications and work orders from SAP directly with the partner

• the service provider sees structure, history, and the digital twin

• status, time, and materials flow back digitally

• if needed, even offline via an MDK app developed by Evora

The result: the process “SAP → BNAC → external technician → BNAC → SAP” becomes end-to-end, transparent, and significantly faster.

BNAC sits alongside and connects other building blocks in the SAP portfolio:

• SAP EAM maps internal processes and accounting logic

• SAP APM uses indicators, sensors, and analytics

• SSAM (SAP Service and Asset Manager) supports mobile maintenance

• BNAC connects external partners and manufacturers via digitized asset and service processes

These components are integrated via SAP Integration Suite on SAP BTP.

BNAC provides the collaborative layer: digital twins, structured partner data, joint order execution. EAM and APM access the same high-quality master data.

For ongoing operations, a structured SAP Application Management Services (AMS) model is recommended – especially when APM, EAM, BNAC, and SSAM are used together.

Instead of launching large programs, a step-by-step approach has proven effective:

1. Select a use case
A clearly defined area such as pumps, valves, handover of new plants, or a specific service partner – the key is clear business value and manageable complexity.

2. Onboard a pilot partner
A manufacturer or service provider who can support digital handover and delivers services regularly.

3. Proof of concept with Evora
Evora sets up BNAC in a preconfigured environment, integrates initial assets, and tests the end-to-end process – from the digital twin through to the external technician’s feedback.

4. Assess scaling potential
Based on real data, ROI can be quantified clearly. Then comes the decision which areas, sites, or partners to onboard next.

If you are already working with SAP APM, SAP EAM, or SAP Service and Asset Manager, BNAC extends your process chain to include the external partner channel – without creating new standalone solutions.
