Microsoft Graph API integration with SAP PO/CPI is one of the most reliable methods for connecting enterprise SAP systems with the Microsoft 365 ecosystem — Azure AD, SharePoint, OneDrive, Teams, and Outlook. This OAuth 2.0-based connection is configured through standard HTTP Adapter channels in both SAP PI/PO and SAP Integration Suite (CPI), eliminating manual data transfers, reducing human error, and enabling seamless process flow between both ecosystems.

Microsoft Graph API is a unified REST API that provides programmatic access to all Microsoft Cloud services through a single endpoint (https://graph.microsoft.com). With a single API key, you can reach data across Azure AD, Exchange Online, SharePoint, OneDrive, Microsoft Teams, OneNote, Planner, and Excel. According to Microsoft’s official documentation, Graph API serves as the gateway to the data of more than 300 million enterprise users in Microsoft 365.

The main operation categories accessible via Graph API include:
Data exchange between SAP systems and Microsoft Graph API is established through SAP PI/PO or SAP Integration Suite (CPI). Both platforms support the OAuth 2.0 Client Credentials flow via standard HTTP Adapter channels — no custom code development is required for the integration.
The technical flow of the integration consists of these steps:

At MDP Group, we have delivered hundreds of projects integrating SAP with the Microsoft ecosystem. The following scenarios represent the most common use cases we encounter when setting up Microsoft Graph API integration with SAP PO/CPI in enterprise environments.
When a new employee is created in the SAP Human Resources module, that information is automatically transferred to Azure AD via the Graph API. The IT team no longer needs to manually create user accounts; the account is ready by the time onboarding begins. Similarly, when an employee leaves, the account is automatically disabled. This scenario significantly accelerates IT processes during large-scale hiring periods.
Reports, invoices, or notifications generated by the SAP ERP system are automatically uploaded to a specified SharePoint folder or OneDrive via the Graph API. This structure creates a centralized archive — especially useful for document sharing with external business partners. Users access their documents without ever logging into SAP.
Critical SAP events (stock threshold reached, invoice pending approval, work order created, etc.) are delivered in real time as messages to a specific Teams channel or user. Thanks to API integration, these notifications are triggered directly by the SAP workflow — no additional middleware required. Teams receive critical alerts instantly without checking any SAP screen.
Work orders, task assignments, or project milestones in SAP are automatically transferred to users’ Outlook calendars via the Graph API. Users can track their tasks from Outlook without logging into SAP at all. This integration is especially beneficial for field teams and frequently traveling managers.
Data collected through SharePoint Power Apps — such as purchase requests, leave forms, or customer records — is forwarded to SAP via the Graph API. This scenario allows end users to enter data without needing access to the SAP interface. User experience improves and data entry errors are reduced.
Several critical points must be considered to ensure the Microsoft Graph API integration with SAP PO/CPI runs smoothly:
Both platforms support Graph API integration, but there are important differences in configuration ease and maintenance. For modern integration architectures, CPI offers a more current option with cloud-native connectors and centralized security management.
If you are planning a migration from SAP PO to CPI, explore our SAP Integration Suite consultancy services or read our comparison of SAP Integration Suite service plans to find the right fit for your organization.
MDP Group designs and deploys Microsoft Graph API integrations on SAP PI/PO and SAP Integration Suite for both standard and customized scenarios. Our solutions cover token management, error handling, retry mechanisms, and monitoring infrastructure. Based on our project experience, using pre-built SAP CPI iFlow templates for most scenarios both reduces implementation time and lowers operational risk. To connect your organization’s Microsoft 365 ecosystem seamlessly through SAP, contact us.
SAP PO and CPI use the OAuth 2.0 Client Credentials flow to connect to Microsoft Graph API. An application registration is created in Azure AD; on the SAP side, Client ID, Client Secret, and Tenant ID are configured. Token acquisition and renewal are managed automatically by the SAP platform — no manual intervention is required.
Synchronization can work in both real-time (event-driven) and batch modes. When an event such as employee creation or update is triggered in SAP HR, the SAP integration platform immediately calls the Graph API to update Azure AD. In batch mode, SAP jobs run at defined intervals to synchronize bulk changes.
SAP Integration Suite (CPI) is the recommended choice for new projects. CPI offers cloud-native OAuth2 security materials, automatic platform updates, and lower maintenance costs. Given SAP PO’s end-of-maintenance date in 2027, existing PO integrations should also be planned for migration to CPI.
Microsoft Graph API enforces request quotas per service. If SAP batch processes generate too many API calls, a 429 (Too Many Requests) error may occur. To prevent this, exponential backoff logic and request batching mechanisms should be implemented in SAP integration flows.
The HTTP Receiver Adapter is used in SAP Integration Suite to connect to Microsoft Graph API. OAuth2 credentials are defined as SAP BTP Security Materials and referenced within the iFlow. This keeps Client Secret values encrypted and centrally manageable across all integration flows.
