Why teams connect SAP S/4HANA and Ukg Ready
Sync the workers, org structure, and cost centers that SAP S/4HANA and Ukg Ready share in real time, so the people Ukg Ready manages stay current in the system that runs finance and operations.
Ukg Ready is the system of record for people: who was hired, which department and location they sit in, who they report to, and how they are paid. SAP S/4HANA runs finance and operations, and much of what it does depends on that same information, from booking labor cost to approving an expense report to staffing a project. Where the two are bridged by re-keying or an overnight file, each side spends the day out of step, with new hires missing from the systems they need and leavers still active where they should not be.
Stacksync syncs Products / Materials, Billing Documents (Invoices), Deliveries, Journal Entries in SAP S/4HANA with Employees, Employment / Positions, Compensation, Timesheet Entries in Ukg Ready field by field, in real time, and in both directions. You decide which system owns which fields, so the people side stays authoritative for worker data while SAP S/4HANA keeps its own accounting and operational detail, and every change made in one is reflected in the other within seconds instead of at the next batch run.
Common use cases
- 01 Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.
- 02 Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.
- 03 Import computed Earnings and deductions into UKG Ready payroll runs from a warehouse or external time-tracking system ahead of each pay period.
- 04 Create new-hire Employee records in UKG Ready from an ATS or onboarding workflow, including position, cost center, and compensation fields.
Common sync patterns
New hires ready to transact in SAP S/4HANA
A new person set up in Ukg Ready becomes an employee record in SAP S/4HANA in time to submit expenses, enter time, or approve a purchase, without waiting on manual setup.
One org structure
Departments, cost centers, and locations that both systems reference stay in agreement, so labor cost, approvals, and reporting in SAP S/4HANA roll up to the same structure Ukg Ready maintains.
Reporting lines drive approvals
Manager and reporting-hierarchy changes in Ukg Ready keep expense and purchase approval chains in SAP S/4HANA pointed at the right people.
What you can sync between SAP S/4HANA and Ukg Ready
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 | Ukg Ready objects | How this pairing syncs | |
|---|---|---|---|
| Purchase Orders Procurement documents shared with supplier portals and spend-management tools. | Payroll (Earnings / Deductions / Employee Payroll Runs) Earnings and deductions can be imported into pay runs; Employee Payroll Runs (gross, net, taxes) read back for GL posting and analytics. | Purchase Orders is specific to SAP S/4HANA and Payroll (Earnings / Deductions / Employee Payroll Runs) to Ukg Ready — each maps to any object or custom field on the other side. | |
| Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs. | Benefits Plan enrollments, coverage tiers, contributions, and effective dates; typically read into benefits or finance systems. | Products / Materials is specific to SAP S/4HANA and Benefits to Ukg Ready — each maps to any object or custom field on the other side. | |
| Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility. | Cost Centers / Groups Departments, locations, and hierarchy used as org structure; read to align headcount and budget models across systems. | Billing Documents (Invoices) is specific to SAP S/4HANA and Cost Centers / Groups to Ukg Ready — each maps to any object or custom field on the other side. | |
| Deliveries Outbound delivery status synced to customer-facing systems for order tracking. | Reports (Report-as-a-Service) Scheduled IBM Cognos extracts used for bulk historical pulls that the per-employee REST endpoints are not built for. | Deliveries is specific to SAP S/4HANA and Reports (Report-as-a-Service) to Ukg Ready — each maps to any object or custom field on the other side. | |
| Journal Entries Financial postings read into warehouses and consolidation tools for reporting. | Employees Core person records (demographics, contact info, status, work location); synced two-way and mapped to HRIS or person tables in a database. | Journal Entries is specific to SAP S/4HANA and Employees to Ukg Ready — 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. | Employment / Positions Job title, department, employment type, hire and termination dates; read for org modeling and written when roles change. | Customer / Supplier Roles is specific to SAP S/4HANA and Employment / Positions to Ukg Ready — each maps to any object or custom field on the other side. |
How changes propagate between SAP S/4HANA and Ukg Ready
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 Ukg Ready 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 Ukg Ready through its API, with automatic retries and rate-limit backoff.
Ukg Ready SAP S/4HANA Sub-second propagation
DetectionUkg Ready notifies Stacksync of record changes through webhook events. UKG Webhooks for select events (employee.created, employee.updated, account/org changes) with HMAC signing.
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.
- Ukg Ready: Rate limits apply over roughly a 1-minute window and return HTTP 429 when exceeded (back off / exponential retry); UKG Webhooks run on a tiered quota with a free tier around 10,000 event notifications per month and 14-day event retention.

FAQ
SAP S/4HANA and Ukg Ready integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between SAP S/4HANA and Ukg Ready: authenticate both systems, choose the objects to sync (such as SAP S/4HANA's Purchase Orders and Products / Materials), 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. Ukg Ready: Rate limits apply over roughly a 1-minute window; exceeding them returns HTTP 429, so high-volume syncs need pacing and backoff. Stacksync's field mapping accounts for these differences between SAP S/4HANA and Ukg Ready 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 Ukg Ready 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 Ukg Ready connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom SAP S/4HANA–Ukg Ready integration in-house.
-
Yes — Stacksync ships production-grade connectors for both SAP S/4HANA and Ukg Ready. 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 Ukg Ready: UKG Webhooks for select events (employee.created, employee.updated, account/org changes) with HMAC signing; broad change capture via polling REST endpoints with date filters or scheduled Report-as-a-Service extracts. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
