Why teams connect SAP S/4HANA and Unleashed Software
Two ERPs, one set of facts: Stacksync keeps SAP S/4HANA and Unleashed Software 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 Journal Entries, Customer / Supplier Roles, Production Orders, Business Partners in SAP S/4HANA with Warehouses, Stock Adjustments, Bills of Materials, Invoices in Unleashed Software 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 Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.
- 02 Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.
- 03 Keep Products and pricing aligned between Unleashed and accounting or PIM systems.
- 04 Mirror Purchase Orders and supplier data to a data warehouse for procurement reporting.
Common sync patterns
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.
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.
What you can sync between SAP S/4HANA and Unleashed Software
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.
| SAP S/4HANA objects | Unleashed Software objects | How this pairing syncs | |
|---|---|---|---|
| Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended. | Sales Orders Outbound orders with lines, status, and fulfillment detail; a common write target from storefronts and CRMs. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Purchase Orders Procurement documents shared with supplier portals and spend-management tools. | Purchase Orders Inbound supply orders synced for procurement visibility. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. | |
| Deliveries Outbound delivery status synced to customer-facing systems for order tracking. | Suppliers Vendor records referenced on purchase orders. | Deliveries is specific to SAP S/4HANA and Suppliers to Unleashed Software — each maps to any object or custom field on the other side. | |
| Journal Entries Financial postings read into warehouses and consolidation tools for reporting. | Warehouses Stock locations that scope inventory quantities and order fulfillment. | Journal Entries is specific to SAP S/4HANA and Warehouses to Unleashed Software — each maps to any object or custom field on the other side. | |
| Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. | Stock Adjustments Manual quantity or value corrections synced for audit and reporting. | Customer / Supplier Roles is specific to SAP S/4HANA and Stock Adjustments to Unleashed Software — each maps to any object or custom field on the other side. | |
| Production Orders Manufacturing order status surfaced in planning and operations tools. | Bills of Materials Production definitions used by assemblies; relevant for manufacturers syncing production data. | Production Orders is specific to SAP S/4HANA and Bills of Materials to Unleashed Software — each maps to any object or custom field on the other side. |
How changes propagate between SAP S/4HANA and Unleashed Software
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.
SAP S/4HANA Unleashed Software 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 Unleashed Software through its API, with automatic retries and rate-limit backoff.
Unleashed Software SAP S/4HANA Interval-based propagation
DetectionStacksync polls Unleashed Software for changes on an incremental schedule, reading only records changed since the previous pass. Polling with modified-date filters on list endpoints.
DeliveryEach detected change is written to SAP S/4HANA through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.
- Unleashed Software: Subject to the platform's API rate limits; paginate list endpoints and batch where possible.

FAQ
SAP S/4HANA and Unleashed Software integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between SAP S/4HANA and Unleashed Software: authenticate both systems, choose the objects to sync (such as SAP S/4HANA's Sales Orders and Purchase Orders), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
SAP S/4HANA: The Business Partner model consolidates what older SAP systems split into separate customer and vendor masters. Unleashed Software: Inventory quantities are tracked per warehouse, so stock syncs are warehouse-scoped rather than a single global figure. Stacksync's field mapping accounts for these differences between SAP S/4HANA and Unleashed Software 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 SAP S/4HANA and Unleashed Software records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed SAP S/4HANA and Unleashed Software connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom SAP S/4HANA–Unleashed Software integration in-house.
-
Yes — Stacksync ships production-grade connectors for both SAP S/4HANA and Unleashed Software. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection 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. On Unleashed Software: Polling with modified-date filters on list endpoints. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
