Why teams connect SAP S/4HANA and Ukg Pro

Sync the workers, org structure, and cost centers that SAP S/4HANA and Ukg Pro share in real time, so the people Ukg Pro manages stay current in the system that runs finance and operations.

Ukg Pro 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 Business Partners, Sales Orders, Purchase Orders, Products / Materials in SAP S/4HANA with Employee (Person Details), Employment Details, Job / Position History, Compensation Details in Ukg Pro 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 Replicate material master and pricing data to e-commerce and quoting tools.
  • 02 Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.
  • 03 Deprovision accounts by subscribing to UKG Pro termination and job-change webhook events to disable IdP and app access as changes become effective.
  • 04 Keep Configuration code tables (jobs, locations, departments, cost centers) aligned between UKG Pro and an ERP so org and cost-center hierarchies match.

Common sync patterns

Reporting lines drive approvals

Manager and reporting-hierarchy changes in Ukg Pro keep expense and purchase approval chains in SAP S/4HANA pointed at the right people.

Where Ukg Pro runs payroll: labor cost in the books

Pay and compensation data from Ukg Pro posts into SAP S/4HANA as labor cost, so finance sees workforce spend without re-entering it by hand.

Where Ukg Pro is the worker system of record: one employee master

When a worker is hired, moved, or offboarded in Ukg Pro, the matching employee record in SAP S/4HANA is created, updated, or deactivated, so the business system reflects the workforce as it actually is.

What you can sync between SAP S/4HANA and Ukg Pro

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 Pro objects How this pairing syncs
Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility. Terminations Termination transactions posted with a terminationDate and a reason code that must match the tenant's configured reason table; drives account deprovisioning. Billing Documents (Invoices) is specific to SAP S/4HANA and Terminations to Ukg Pro — each maps to any object or custom field on the other side.
Deliveries Outbound delivery status synced to customer-facing systems for order tracking. Configuration Setup (Code Tables) Reference data such as jobs, locations, positions, earnings, and deduction codes; used to resolve and validate field values when mapping records during sync. Deliveries is specific to SAP S/4HANA and Configuration Setup (Code Tables) to Ukg Pro — each maps to any object or custom field on the other side.
Journal Entries Financial postings read into warehouses and consolidation tools for reporting. Time & Attendance (UTA) Timekeeping and worked-hours data exposed by the UTA services; synced into scheduling, payroll, or workforce-analytics databases. Journal Entries is specific to SAP S/4HANA and Time & Attendance (UTA) to Ukg Pro — 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. Employee (Person Details) Core worker record with demographics and identifiers; read by listing employee IDs then fetching each profile, and created on hire via the personnel/onboarding endpoints. Customer / Supplier Roles is specific to SAP S/4HANA and Employee (Person Details) to Ukg Pro — each maps to any object or custom field on the other side.
Production Orders Manufacturing order status surfaced in planning and operations tools. Employment Details Employment status, hire and service dates, and company assignment; the record that drives active/terminated state for provisioning downstream. Production Orders is specific to SAP S/4HANA and Employment Details to Ukg Pro — each maps to any object or custom field on the other side.
Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs. Job / Position History Effective-dated job, position, department, supervisor, location, and cost center; the most-synced record for org charts, provisioning, and analytics. Business Partners is specific to SAP S/4HANA and Job / Position History to Ukg Pro — each maps to any object or custom field on the other side.

How changes propagate between SAP S/4HANA and Ukg Pro

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 Pro 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 Pro through its API, with automatic retries and rate-limit backoff.

Ukg Pro SAP S/4HANA Sub-second propagation

DetectionUkg Pro notifies Stacksync of record changes through webhook events. No CDC stream.

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 Pro: An API gateway throttles calls per client over a rolling window (typically per minute); UKG does not publish exact numeric thresholds. Exceeding the limit returns HTTP 429, and UKG recommends a roughly one-second looping backoff before resuming (a Retry-After header is not yet standard). Reads are offset-paginated.

How the SAP S/4HANA and Ukg Pro connectors work

SAP S/4HANA

Integration surface
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
Change detection

Ukg Pro

Integration surface
REST API (UKG Pro HCM REST services) with separate Onboarding and Recruiting REST APIs, plus legacy SOAP-based UKG Pro Web Services
Authentication
Core HCM REST APIs use HTTP Basic authentication with a dedicated web service account, plus a Customer API Key and a User API Key sent as headers (found under System Configuration > Security > Service Account Administration); the Onboarding and Recruiting REST APIs instead require a bearer Authorization Token from the token endpoint.
Change detection
No CDC stream. UKG Pro publishes Pro HCM Webhook Events for changes such as new hire, employee and job detail changes, termination, and PTO, which Stacksync subscribes to for near-real-time triggers; bulk and historical loads use paged reads with each service's modified-since filters.
