Why teams connect Infor LN and SAP S/4HANA
Two ERPs, one set of facts: Stacksync keeps Infor LN 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 Business partners, Sales orders, Purchase orders, Production orders in Infor LN with Deliveries, Journal Entries, Customer / Supplier Roles, Production 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 Run a two-way sync of business partners between LN and a CRM so sales and manufacturing share account data.
- 02 Keep inventory positions aligned between LN and distribution or aftermarket service systems.
- 03 Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.
- 04 Replicate material master and pricing data to e-commerce and quoting tools.
Common sync patterns
Shared master data
Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.
Split by function
Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.
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.
What you can sync between Infor LN 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 LN objects | SAP S/4HANA objects | How this pairing syncs | |
|---|---|---|---|
| Business partners LN's unified customer/supplier records matched against CRM accounts. | Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping. | |
| Sales orders Demand documents synced in from EDI and commerce channels. | 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 Supply documents shared with supplier and procurement systems. | 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. | |
| Production orders Shop-floor work orders synced with MES for execution visibility. | Production Orders Manufacturing order status surfaced in planning and operations tools. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Items Manufacturing item masters synced to PLM, MES, and commerce systems. | Deliveries Outbound delivery status synced to customer-facing systems for order tracking. | Items is specific to Infor LN and Deliveries to SAP S/4HANA — each maps to any object or custom field on the other side. | |
| Bills of material Product structures shared with engineering and planning tools. | Journal Entries Financial postings read into warehouses and consolidation tools for reporting. | Bills of material is specific to Infor LN and Journal Entries to SAP S/4HANA — each maps to any object or custom field on the other side. |
How changes propagate between Infor LN 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 LN SAP S/4HANA Interval-based propagation
DetectionStacksync polls Infor LN for changes on an incremental schedule, reading only records changed since the previous pass. Event-style BOD publications through Infor ION where configured.
DeliveryEach detected change is written to SAP S/4HANA through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations
- Infor LN: Subject to the ION API gateway's tenant rate limits in cloud deployments.
- SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.

-
Yes. Stacksync provides a managed, real-time two-way integration between Infor LN and SAP S/4HANA: authenticate both systems, choose the objects to sync (such as Infor LN's Business partners and Sales orders), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Change detection on Infor LN: Event-style BOD publications through Infor ION where configured; otherwise polling. 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.
-
On the Infor LN side: Business partners, Sales orders, Purchase orders, Production orders, plus custom fields where Infor LN exposes them. On the SAP S/4HANA side: Deliveries, Journal Entries, Customer / Supplier Roles, Production Orders. Stacksync auto-detects both schemas and converts types between the two systems.
-
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 LN and SAP S/4HANA: Shared master data; Split by function; Two-tier roll-up. Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.
