Why teams connect Ceridian Dayforce and SAP S/4HANA

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

Ceridian Dayforce 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 Time Away From Work & Balances, Employee (HR / Person Details), Employment Status, Work Assignments in Ceridian Dayforce 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 Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.
  • 02 Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.
  • 03 Sync time data by posting raw clock entries from a third-party scheduling tool into Dayforce, or pulling Employee Punches and Schedules into a workforce-analytics database.
  • 04 Two-way sync of Employee and Work Assignment data (position, department, location, org unit) into Postgres so provisioning, internal apps, and analytics read current worker and org data in SQL while HR keeps editing in Dayforce.

Common sync patterns

Reporting lines drive approvals

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

Where Ceridian Dayforce runs payroll: labor cost in the books

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

Where Ceridian Dayforce is the worker system of record: one employee master

When a worker is hired, moved, or offboarded in Ceridian Dayforce, 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 Ceridian Dayforce 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.

Ceridian Dayforce objects SAP S/4HANA objects How this pairing syncs
Employment Status Effective-dated employment status and type (active, leave, terminated) that drives active/terminated state for downstream provisioning; read, and writable as new dated status records. Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. Employment Status is specific to Ceridian Dayforce and Customer / Supplier Roles to SAP S/4HANA — each maps to any object or custom field on the other side.
Work Assignments Effective-dated position, department, location, and org-unit assignment; the most-synced record for org charts, provisioning, and analytics. Read and updatable via PATCH. Production Orders Manufacturing order status surfaced in planning and operations tools. Work Assignments is specific to Ceridian Dayforce and Production Orders to SAP S/4HANA — each maps to any object or custom field on the other side.
Compensation Summary & Pay Adjustments Compensation Summary returns pay rate and frequency for reporting; Employee Pay Adjustments are written as effective-dated records via PATCH to post pay changes back to Dayforce. Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs. Compensation Summary & Pay Adjustments is specific to Ceridian Dayforce and Business Partners to SAP S/4HANA — each maps to any object or custom field on the other side.
Employee Punches & Raw Clock Entries Time-and-attendance punches; raw clock entries are added with POST and punches removed with DELETE, so time data flows both ways between Dayforce and scheduling or workforce tools. Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended. Employee Punches & Raw Clock Entries is specific to Ceridian Dayforce and Sales Orders to SAP S/4HANA — each maps to any object or custom field on the other side.
Employee Schedules Shift and schedule assignments; created and updated through POST and PATCH schedule endpoints and paged with pageSize, used to push schedules from a WFM tool or pull them for analytics. Purchase Orders Procurement documents shared with supplier portals and spend-management tools. Employee Schedules is specific to Ceridian Dayforce and Purchase Orders to SAP S/4HANA — each maps to any object or custom field on the other side.
Org Units, Departments, Jobs & Positions Configuration reference data; POST creates org units and departments and PATCH updates job, position, department, and org-unit data. Used to resolve and validate XRefCodes when mapping employee writes. Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs. Org Units, Departments, Jobs & Positions is specific to Ceridian Dayforce and Products / Materials to SAP S/4HANA — each maps to any object or custom field on the other side.

How changes propagate between Ceridian Dayforce 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.

Ceridian Dayforce SAP S/4HANA Sub-second propagation

DetectionCeridian Dayforce 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.

SAP S/4HANA Ceridian Dayforce 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 Ceridian Dayforce through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Ceridian Dayforce: Dayforce does not publish numeric rate limits; thresholds vary by tenant and exceeding them returns HTTP 429, so large employee reads are paged (pageSize) and throttled with backoff. Employee list calls return XRefCodes only, so each employee needs a follow-up GET.
  • SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.

How the Ceridian Dayforce and SAP S/4HANA connectors work

Ceridian Dayforce

Integration surface
REST API (Dayforce RESTful Web Services, v1/v2), JSON payloads
Authentication
HTTP Basic authentication with a dedicated Web Services user plus the client namespace (Company ID), or an OAuth 2.0 access token from the Dayforce identity endpoint (POST dfid.dayforcehcm.com/connect/token, client_id Dayforce.HCMAnywhere.Client). Token-based auth is recommended, and the Web Services role with the Read Data subfeature must be enabled on the account.
Change detection
No CDC stream. Broad change detection uses delta polling on GET Employees with filterUpdatedStartDate/filterUpdatedEndDate and filterUpdatedEntities to pull only records changed in a window. Dayforce also has native Event Notifications (the Notification Publisher) for lifecycle events — hire, rehire, terminate, and workflow validation — delivered by push to a receiver service or by querying unacknowledged notifications; the publisher runs roughly hourly and each notification must be acknowledged.
