To integrate SAP with Microsoft Copilot and Power Platform in 2026 you choose among four proven patterns: the SAP ERP and SAP OData connectors for building Power Apps, Power Automate flows, and custom Copilot Studio agents on SAP data; the managed SAP Joule and Microsoft 365 Copilot integration for out-of-the-box question-and-answer across both systems; agent-to-agent (A2A) interoperability for orchestrating Copilot Studio and Joule agents together; and SAP Business Data Cloud Connect for Microsoft Fabric for zero-copy analytics. Which one you pick depends on whether you need to build custom logic, surface SAP data to Microsoft 365 users, coordinate agents across both stacks, or run analytics without moving data.

This guide is written for IT directors, enterprise architects, and operations leaders who already run SAP and Microsoft 365 and want a straight answer on how the two connect, what each pattern costs to stand up, and where the governance work actually lives. Roughly 70% of the Fortune 500 run both SAP and Microsoft's enterprise stack, so this is one of the most common integration decisions on the table right now.

Key Takeaways

• There are four distinct SAP-to-Microsoft patterns, not one. Connectors, managed Joule-Copilot, agent-to-agent orchestration, and Fabric data sharing solve different problems and are often combined.
• The choice starts with a single question: build or consume. If you need custom logic and actions, use the Power Platform SAP connectors; if you need SAP answers inside Microsoft 365 with no build, use the managed Joule integration.
• The managed Joule-Copilot integration does not cover custom Copilot Studio agents. Microsoft is explicit that custom-built agents are a separate path that uses the connectors or A2A, not the out-of-the-box feature.
• Identity is the hard part, not the pipe. Every pattern depends on a correctly configured trust between Microsoft Entra ID and SAP, whether that is Kerberos, certificates, or SAP Cloud Identity Services.
• 2026 changed the analytics story. SAP Business Data Cloud Connect for Microsoft Fabric reaches general availability in Q3 2026, enabling zero-copy sharing to OneLake and removing the nightly SAP-to-Power BI extract.

What are the ways to connect SAP and Microsoft, and which do you need?

The short answer: pick the pattern that matches your goal, then layer identity and governance underneath it. Most enterprises end up running two or three of these together rather than choosing one.

• Build custom apps, flows, or agents on SAP data — use the Power Platform SAP ERP or SAP OData connectors.
• Give Microsoft 365 users SAP answers with no development — use the managed SAP Joule and Microsoft 365 Copilot integration.
• Coordinate Copilot Studio and Joule agents in one workflow — use agent-to-agent (A2A) interoperability.
• Run Power BI and Fabric analytics on SAP data without ETL — use SAP Business Data Cloud Connect for Microsoft Fabric.

What are the SAP connectors for Power Platform, and when do you use each?

Microsoft ships two first-party connectors for SAP, and the difference between them is protocol and reach. Both support encryption in motion, and both let you build apps, automated flows, and custom Copilot Studio agents that read and write SAP data, per Microsoft Learn's Power Platform and SAP connection guidance.

SAP ERP connector versus SAP OData connector

SAP ERP connector

• Protocol: SAP Remote Function Calls (RFCs), including BAPIs, tables, and IDOCs.
• Works with: SAP ECC, S/4HANA, and any SAP product on the NetWeaver stack.
• Operations: Create, read, and update SAP data on SAP's API layer, which typically outperforms the same activity run through the SAP GUI.
• Authentication: SAP authentication, Windows authentication, Microsoft Entra ID via Kerberos, and Microsoft Entra ID via certificates.
• Best for: Deep transactional integration — for example calling BAPI_SALESORDER_CREATEFROMDAT2 to create a sales order from a Power App.

SAP OData connector

• Protocol: OData Version 4.01 over HTTP.
• Works with: Any SAP product that exposes OData 4.01 endpoints; ECC and earlier need endpoints configured that are not in the out-of-box setup.
• Operations: Standardized, HTTP-based data access that is generally simpler to consume.
• Authentication: Basic, anonymous, Microsoft Entra ID via Azure API Management, and Microsoft Entra ID via SuccessFactors.
• Best for: Modern S/4HANA and cloud SAP landscapes where clean OData services already exist.

For on-premises SAP, both connectors reach the system through an on-premises data gateway, which acts as a secure proxy between your Microsoft cloud tenant and SAP. Microsoft recommends a Windows VM with at least 8 GB of RAM, a clustered gateway for production to avoid single points of failure, and a separate gateway per environment so development testing never touches production.

How does the managed SAP Joule and Microsoft Copilot integration work?

The managed integration is the no-build option. It brings SAP's Joule assistant into Microsoft Copilot and Teams so users can ask SAP questions without opening a Fiori screen, and lets Joule users reach Microsoft 365 context in return. Microsoft's Joule and Copilot integration documentation describes it as a bidirectional, trust-based feature that needs no custom agent.

In practice, a user in Copilot or Teams tags a request with "@Joule" — for example, "@Joule show me open purchase orders past their expected delivery date" — and the request routes to SAP for processing before the answer returns inside Copilot. It works today with SAP S/4HANA Cloud (Private and Public Edition), SAP SuccessFactors, and selected SAP Ariba scenarios.

The prerequisites are specific: a Microsoft 365 Copilot license plus the corresponding SAP licenses, an SAP Business Technology Platform account with Identity Authentication Service configured in SAP Cloud Identity Services, and a Microsoft Entra ID tenant with admin access. The integration rests on a trust relationship between SAP Cloud Identity Services and Entra ID that maps each Microsoft user to an SAP user. One critical boundary: this managed feature does not route custom agents built in Copilot Studio — those need the connectors or A2A instead.

What is agent-to-agent (A2A) integration between Copilot Studio and Joule?

Agent-to-agent interoperability, announced at SAP Sapphire 2026, lets Copilot Studio agents and SAP Joule agents call each other through an open, vendor-neutral A2A protocol, with Copilot Studio acting as the orchestration layer that consumes Joule services as invokable skills. This is the pattern for cross-platform workflows that neither the connectors nor the managed integration handle cleanly on their own.

Concretely, a Microsoft Copilot agent handling a customer complaint in Dynamics 365 can hand off to a Joule agent to check open orders, credit limit, and delivery status in SAP, then hand back to complete the response. The value is that A2A removes the custom middleware that historically sat between the two ecosystems — integrations that once took months can be configured through the agent builders instead.

The pipe is rarely what stalls an SAP-to-Microsoft project; the identity trust, authorization objects, and data governance underneath it are.

If you are weighing whether to build custom Copilot Studio agents on SAP or lean on the managed and A2A paths, this is exactly the kind of decision BabyBots scopes in a fixed-fee SAP-and-Microsoft integration assessment — we map your landscape, the right pattern per use case, and the identity work before a line of production logic gets built. It is also where our published SAP integration case studies, spanning SAP Ariba EDI, SAP MDG intake, and SAP-to-Power BI reporting, come from.

How do you get SAP data into Power BI and Fabric without ETL?

The 2026 answer is SAP Business Data Cloud Connect for Microsoft Fabric, which reaches general availability in Q3 2026 and enables bidirectional zero-copy delta sharing between SAP Business Data Cloud and Microsoft OneLake. The point is that SAP data lands in OneLake as a live, governed, delta-shared dataset — no nightly extract, no replication pipeline, and SAP's governance perimeter stays intact.

For data teams, this collapses the parallel pipelines most organizations maintain today. Power BI reports built on governed SAP data products update from the source rather than a stale export, and Fabric machine-learning workloads can train on SAP data in place. If Power BI is your dominant BI tool, this is the pattern that finally makes real-time SAP analytics practical without maintaining a fragile extract-transform-load layer.

Which SAP-to-Microsoft integration pattern should you choose?

Match the pattern to the outcome you actually need, then expect to combine them. A useful decision sequence:

1. Do users just need SAP answers inside Microsoft 365? Start with the managed Joule-Copilot integration — it is the fastest path and requires no build.
2. Do you need to create, update, or act on SAP data from custom apps or agents? Use the SAP ERP connector for RFC/BAPI depth or the SAP OData connector for modern OData services.
3. Do you need a workflow that spans Copilot Studio and Joule agents? Use A2A orchestration.
4. Do you need governed SAP data in Power BI and Fabric? Use SAP Business Data Cloud Connect for Microsoft Fabric.

Handling SAP objects that lack an API is a common gotcha. For those, the connector guidance points to IDocs, batch input recordings, Legacy System Migration Workbench files, or a custom remote-enabled function module — and any BAPI or custom RFC call requires the executing user to hold the S_RFC authorization object in SAP.

Frequently Asked Questions

Do I need SAP BTP to connect SAP and Microsoft?

It depends on the pattern. The Power Platform SAP ERP and SAP OData connectors do not require SAP Business Technology Platform — they connect through a connector and, for on-premises SAP, an on-premises data gateway. The managed SAP Joule and Microsoft 365 Copilot integration does require a BTP account with Identity Authentication Service configured, because the trust relationship runs through SAP Cloud Identity Services.

What is the difference between the SAP ERP connector and the SAP OData connector?

The SAP ERP connector uses the RFC protocol and calls BAPIs, tables, and IDOCs, making it the right choice for deep transactional create/read/update work across ECC, S/4HANA, and NetWeaver systems. The SAP OData connector uses OData 4.01 over HTTP and is generally simpler to consume, which suits modern S/4HANA and cloud SAP landscapes that already expose clean OData services.

Can Microsoft Copilot write data back to SAP, or only read it?

Custom agents and flows built on the SAP ERP connector can create and update SAP data, not just read it — for example creating a sales order through a BAPI call. The managed Joule-Copilot integration is oriented toward retrieving answers and running Joule's built-in capabilities; custom write-back logic belongs in the connector or A2A patterns rather than the out-of-the-box feature.

Does the managed Joule-Copilot integration support custom Copilot Studio agents?

No. Microsoft is explicit that the managed integration is limited to Joule's built-in capabilities and does not route custom skills or agents built in Copilot Studio. If you need custom agents that reach SAP, you use the Power Platform connectors or agent-to-agent interoperability instead.

How do I secure the connection between Power Platform and on-premises SAP?

Traffic flows through an on-premises data gateway that acts as a proxy between your tenant and SAP, and Secure Network Communications encrypts data between the gateway and SAP. For production, run a clustered gateway to remove single points of failure and use a separate gateway per environment. Authentication should use Microsoft Entra ID via Kerberos or certificates where possible rather than static SAP credentials.

When will zero-copy SAP data sharing with Microsoft Fabric be available?

SAP Business Data Cloud Connect for Microsoft Fabric is targeted for general availability in Q3 2026. It enables bidirectional zero-copy delta sharing between SAP Business Data Cloud and Microsoft OneLake, which removes the need to replicate SAP data into Power BI through nightly extracts.

Where this is heading

The direction of travel is clear: SAP and Microsoft are converging their AI and data layers so that the boundary between systems of record and systems of engagement keeps thinning. As A2A orchestration and zero-copy Fabric sharing move to general availability, the hard part of these projects shifts away from connectivity and toward governance — identity mapping, authorization scoping, and keeping SAP's data governance intact as more Microsoft 365 users reach live SAP data. The enterprises that plan the identity and governance layer first will get value from these patterns; the ones that treat integration as a pipe will inherit a control problem.
