Why teams connect Dynamics 365 F&O and SAP S/4HANA
Two ERPs, one set of facts: Stacksync keeps Dynamics 365 F&O and SAP S/4HANA consistent in real time, whether they split the business or one is replacing the other.
Large enterprises frequently operate Dynamics 365 F&O and SAP S/4HANA side by side across regions, divisions, or post-merger entities. Bi-directional sync between F&O Customers and Vendors and S/4HANA Business Partners, and between the two systems' Sales Orders and Purchase Orders, keeps master data and transaction state consistent across both tier-1 ERPs.
Stacksync syncs General Journal Entries, On-hand Inventory, Customers, Vendors in Dynamics 365 F&O with Business Partners, Sales Orders, Purchase Orders, Products / Materials in SAP S/4HANA bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.
Common use cases
- 01 Maintain one customer and vendor master across divisions split between F&O and S/4HANA after a merger.
- 02 Run a multi-year ERP consolidation with Products / Materials and Released Products kept in lockstep during coexistence.
- 03 Give group finance matched Billing Documents and Customer Invoices without spreadsheet reconciliation.
- 04 Distribute product and price master data from F&O to downstream channels through a synced database.
Common sync patterns
Master data harmonization
S/4HANA Business Partners and Products / Materials sync with F&O Customers, Vendors, and Released Products across both ERPs.
Cross-ERP order processing
Sales Orders and Purchase Orders replicate between F&O and S/4HANA so divisions trading with each other see the same order state.
Billing reconciliation
S/4HANA Billing Documents stay matched to F&O Customer Invoices for group-level receivables reporting.
What you can sync between Dynamics 365 F&O and SAP S/4HANA
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.
| Dynamics 365 F&O objects | SAP S/4HANA objects | How this pairing syncs | |
|---|---|---|---|
| Sales Orders Order transactions; written in from storefronts or CRM and tracked through fulfillment. | Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Purchase Orders Procurement transactions; extracted for spend and supply chain reporting. | Purchase Orders Procurement documents shared with supplier portals and spend-management tools. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Vendors Supplier master records; synced with procurement and AP tools. | Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs. | Vendors is specific to Dynamics 365 F&O and Business Partners to SAP S/4HANA — each maps to any object or custom field on the other side. | |
| Released Products Sellable product master; read out to commerce channels and CRM catalogs. | Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs. | Released Products is specific to Dynamics 365 F&O and Products / Materials to SAP S/4HANA — each maps to any object or custom field on the other side. | |
| Customer Invoices AR billing documents; status synced back to CRM and customer success tools. | Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility. | Customer Invoices is specific to Dynamics 365 F&O and Billing Documents (Invoices) to SAP S/4HANA — each maps to any object or custom field on the other side. | |
| Vendor Invoices AP documents; synced with invoice automation systems. | Deliveries Outbound delivery status synced to customer-facing systems for order tracking. | Vendor Invoices is specific to Dynamics 365 F&O and Deliveries to SAP S/4HANA — each maps to any object or custom field on the other side. |
How changes propagate between Dynamics 365 F&O and SAP S/4HANA
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.
Dynamics 365 F&O SAP S/4HANA Sub-second propagation
DetectionDynamics 365 F&O pushes changes as they happen — webhook events backed by change data capture. Change data capture via the Dynamics 365 Change Tracking feature, enabled per entity.
DeliveryEach detected change is written to SAP S/4HANA through its API, with automatic retries and rate-limit backoff.
SAP S/4HANA Dynamics 365 F&O Interval-based propagation
DetectionStacksync polls SAP S/4HANA for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change timestamps exposed by the OData services.
DeliveryEach detected change is written to Dynamics 365 F&O through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Dynamics 365 F&O: OData requests are subject to platform throttling; high-volume loads belong in the Data Management Framework.
- SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.

FAQ
Dynamics 365 F&O and SAP S/4HANA integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Dynamics 365 F&O and SAP S/4HANA: authenticate both systems, choose the objects to sync (such as Dynamics 365 F&O's Sales Orders and Purchase Orders), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Dynamics 365 F&O: Integration goes through data entities, which are denormalized views over the underlying tables; raw tables are not exposed directly. SAP S/4HANA: The Business Partner model consolidates what older SAP systems split into separate customer and vendor masters. Stacksync's field mapping accounts for these differences between Dynamics 365 F&O and SAP S/4HANA without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Dynamics 365 F&O and SAP S/4HANA records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Dynamics 365 F&O and SAP S/4HANA connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Dynamics 365 F&O–SAP S/4HANA integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Dynamics 365 F&O and SAP S/4HANA. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Dynamics 365 F&O: Change data capture via the Dynamics 365 Change Tracking feature, enabled per entity; falls back to periodic full-sync where change tracking is unavailable. On SAP S/4HANA: Polling on change timestamps exposed by the OData services; business events can be emitted through SAP's event infrastructure on cloud editions. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
