Why teams connect Infor M3 and SAP S/4HANA
Two ERPs, one set of facts: Stacksync keeps Infor M3 and SAP S/4HANA consistent in real time, whether they split the business or one is replacing the other.
Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.
Stacksync syncs Customers, Suppliers, Customer Orders, Purchase Orders in Infor M3 with Production Orders, Business Partners, Sales Orders, Purchase Orders 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 Keep supplier and purchase order data aligned between M3 and procurement tools
- 02 Consolidate M3 transactional data into an analytics database for cross-plant reporting
- 03 Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.
- 04 Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.
Common sync patterns
Two-tier roll-up
Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.
Migration in parallel
When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.
Shared master data
Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.
What you can sync between Infor M3 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.
| Infor M3 objects | SAP S/4HANA objects | How this pairing syncs | |
|---|---|---|---|
| Purchase Orders PO headers and lines sync outward so buyers and receiving teams see the same demand. | 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. | |
| Manufacturing Orders Production order status feeds portals and CRMs so promised dates reflect the shop floor. | Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. | Manufacturing Orders is specific to Infor M3 and Customer / Supplier Roles to SAP S/4HANA — each maps to any object or custom field on the other side. | |
| Inventory Balances On-hand quantities by warehouse drive available-to-promise in downstream channels. | Production Orders Manufacturing order status surfaced in planning and operations tools. | Inventory Balances is specific to Infor M3 and Production Orders to SAP S/4HANA — each maps to any object or custom field on the other side. | |
| Invoices Billing documents flow to finance and CRM tools for AR visibility. | Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs. | Invoices is specific to Infor M3 and Business Partners to SAP S/4HANA — each maps to any object or custom field on the other side. | |
| Warehouses Warehouse and facility records scope inventory and order data during mapping. | Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended. | Warehouses is specific to Infor M3 and Sales Orders to SAP S/4HANA — each maps to any object or custom field on the other side. | |
| Price Lists Pricing data keeps quoting tools consistent with the prices M3 will actually invoice. | Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs. | Price Lists is specific to Infor M3 and Products / Materials to SAP S/4HANA — each maps to any object or custom field on the other side. |
How changes propagate between Infor M3 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.
Infor M3 SAP S/4HANA Sub-second propagation
DetectionInfor M3 notifies Stacksync of record changes through webhook events. Event publishing through Infor ION (Business Object Documents), configured in ION, or scheduled polling of API endpoints.
DeliveryEach detected change is written to SAP S/4HANA through its API, with automatic retries and rate-limit backoff.
SAP S/4HANA Infor M3 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 Infor M3 through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Infor M3: Subject to Infor ION API gateway throttling policies.
- SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.

FAQ
Infor M3 and SAP S/4HANA integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Infor M3 and SAP S/4HANA: authenticate both systems, choose the objects to sync (such as Infor M3's Purchase Orders and Manufacturing Orders), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
-
Common patterns for Infor M3 and SAP S/4HANA: Two-tier roll-up; Migration in parallel; Shared master data. Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.
-
Infor M3: REST API (M3 API programs exposed through the Infor ION API gateway). Authentication: OAuth 2.0 via Infor OS / ION API authorization. SAP S/4HANA: OData REST APIs (v2/v4), with SOAP, BAPI/RFC, and IDoc interfaces on on-premise editions. Authentication: OAuth 2.0 with communication arrangements on cloud editions; basic auth or certificate-based on-premise. Stacksync manages authentication, retries, and rate limits on both sides.
-
Infor M3: Most M3 records are scoped by a company, division, facility, and warehouse hierarchy, which integration mappings need to carry explicitly. 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 Infor M3 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 Infor M3 and SAP S/4HANA records are not retained after a sync operation.
