Why teams connect SAP S/4HANA and Smartrecruiters
Sync the workers, org structure, and cost centers that SAP S/4HANA and Smartrecruiters share in real time, so the people Smartrecruiters manages stay current in the system that runs finance and operations.
Smartrecruiters 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 Jobs, Job Postings, Interviews, Offers in Smartrecruiters 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 Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.
- 02 Replicate material master and pricing data to e-commerce and quoting tools.
- 03 Export Interviews and Offers to a data warehouse to analyze interviewer load, offer-acceptance rates, and hiring outcomes.
- 04 Subscribe to the Webhooks API to react to new applications and status changes in near real time across downstream systems.
Common sync patterns
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 Smartrecruiters maintains.
Reporting lines drive approvals
Manager and reporting-hierarchy changes in Smartrecruiters keep expense and purchase approval chains in SAP S/4HANA pointed at the right people.
Where Smartrecruiters runs payroll: labor cost in the books
Pay and compensation data from Smartrecruiters posts into SAP S/4HANA as labor cost, so finance sees workforce spend without re-entering it by hand.
What you can sync between SAP S/4HANA and Smartrecruiters
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 | Smartrecruiters objects | How this pairing syncs | |
|---|---|---|---|
| Production Orders Manufacturing order status surfaced in planning and operations tools. | Offers Offer records tied to an Application with status, custom offer fields, and offer documents; readable and writable, commonly synced to an HRIS on hire (documents endpoint limited to 2 requests/sec). | Production Orders is specific to SAP S/4HANA and Offers to Smartrecruiters — 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. | Users Company users (recruiters, hiring managers) with roles, access groups, and activation state; read and written via the User Management API. | Business Partners is specific to SAP S/4HANA and Users to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended. | Approvals Approval requests for jobs and offers; requests can be created, retrieved as pending, commented on, and approved or rejected via the Approvals API. | Sales Orders is specific to SAP S/4HANA and Approvals to Smartrecruiters — each maps to any object or custom field on the other side. | |
| Purchase Orders Procurement documents shared with supplier portals and spend-management tools. | Candidates Person records with contact details, tags, attachments, custom properties, and consent; created, updated, and searched via the Candidates API, often populated from sourcing or enrichment pipelines. | Purchase Orders is specific to SAP S/4HANA and Candidates to Smartrecruiters — 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. | Applications Links a Candidate to a Job and carries the current hiring status and source; created and advanced through statuses (screening, interview, offer, hired, rejected) via the Application API. | Products / Materials is specific to SAP S/4HANA and Applications to Smartrecruiters — 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. | Jobs Requisitions (positions) with openings, departments, locations, and hiring team; created, patched, and read out for requisition and time-to-fill reporting via the Jobs API. | Billing Documents (Invoices) is specific to SAP S/4HANA and Jobs to Smartrecruiters — each maps to any object or custom field on the other side. |
How changes propagate between SAP S/4HANA and Smartrecruiters
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 Smartrecruiters 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 Smartrecruiters through its API, with automatic retries and rate-limit backoff.
Smartrecruiters SAP S/4HANA Sub-second propagation
DetectionSmartrecruiters notifies Stacksync of record changes through webhook events. Webhooks API — subscribe to events (new application, candidate updated, status changed) delivered with a signing secret and retrievable callback logs.
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.
- Smartrecruiters: Per API credential: most endpoints allow up to 10 requests/sec (job publication and offer documents 2/sec), plus a concurrency limiter of up to 8 simultaneous requests (GET /candidates capped at 1). Exceeding returns 429; responses carry X-RateLimit-Limit/Remaining and concurrent-limit headers.
