Why teams connect Microsoft 365 and SAP Hana

Mirror Microsoft 365's data into SAP Hana so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Microsoft 365 through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in SAP Hana.

Stacksync mirrors Mail Messages, Calendar Events, Contacts, OneDrive Files (driveItems) from Microsoft 365 into Calculation views, SQL views, Schemas, Sequences in SAP Hana and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Microsoft 365, so the tool and the database never disagree.

Common use cases

  • 01 Keep CRM contacts and Microsoft 365 contacts aligned in both directions.
  • 02 Sync employee records from an HR system into Entra ID users and group memberships.
  • 03 Read SYS.TABLES and TABLE_COLUMNS system views to auto-discover schema and generate field mappings when new tables are added to the sync.
  • 04 Detect inserts, updates, and deletes on high-write tables via AFTER triggers or a last-modified column and replicate the deltas downstream near-real-time.

Common sync patterns

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Microsoft 365 with a query

Records from Microsoft 365 are ordinary rows in SAP Hana; join them, index them, and use them in application logic without touching the vendor API.

Automate Microsoft 365 from your codebase

Write to the synced tables in SAP Hana and Stacksync propagates the change into Microsoft 365, replacing custom integration code.

What you can sync between Microsoft 365 and SAP Hana

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Microsoft 365 objects SAP Hana objects How this pairing syncs
Mail Messages Exchange Online messages read for logging, archiving, or activity capture. Sequences Server-generated key values; relevant when writing rows into tables whose identity is assigned HANA-side rather than by the source system. Mail Messages is specific to Microsoft 365 and Sequences to SAP Hana — each maps to any object or custom field on the other side.
Calendar Events Events synced with scheduling tools and CRMs for meeting visibility. Triggers AFTER INSERT/UPDATE/DELETE triggers capture changes into a shadow/logging table so updates and deletes are detected near-real-time without full scans. Calendar Events is specific to Microsoft 365 and Triggers to SAP Hana — each maps to any object or custom field on the other side.
Contacts Personal and org contacts kept consistent with CRM contact records. System-versioned temporal tables Column store tables with a history table tracking each row's validity period; used to reconstruct update and delete history for change capture. Contacts is specific to Microsoft 365 and System-versioned temporal tables to SAP Hana — each maps to any object or custom field on the other side.
OneDrive Files (driveItems) File and folder metadata synced for document workflows and audits. System views (SYS schema) Catalog and monitoring views such as SYS.TABLES and TABLE_COLUMNS; read to discover schema and auto-generate field mappings for new tables. OneDrive Files (driveItems) is specific to Microsoft 365 and System views (SYS schema) to SAP Hana — each maps to any object or custom field on the other side.
SharePoint Sites & Lists List items read and written like lightweight database tables. Column store tables HANA's default table type, optimized for analytics; synced two-way as rows over the SQL interface with the primary key driving upserts and delete tracking. SharePoint Sites & Lists is specific to Microsoft 365 and Column store tables to SAP Hana — each maps to any object or custom field on the other side.
Teams Team and membership data provisioned from upstream systems. Row store tables OLTP-oriented tables held fully in memory; read and written the same way through the SAP HANA client for high-write operational tables. Teams is specific to Microsoft 365 and Row store tables to SAP Hana — each maps to any object or custom field on the other side.

How changes propagate between Microsoft 365 and SAP Hana

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Microsoft 365 SAP Hana Sub-second propagation

DetectionMicrosoft 365 notifies Stacksync of record changes through webhook events. Graph change notifications (webhooks) plus delta queries for incremental sync.

DeliveryEach detected change is applied to SAP Hana as a row-level write, with types converted between the two schemas.

SAP Hana Microsoft 365 Sub-second propagation

DetectionChanges in SAP Hana are captured at the source via change data capture — no polling loop against its API. Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table.

DeliveryEach detected change is written to Microsoft 365 through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • SAP Hana: No SaaS-style request quota; throughput is bounded by connection limits, statement memory caps, and workload-class admission control (concurrency/memory limits) that share capacity with production queries.
