Why teams connect SAP and Smartrecruiters

Sync the workers, org structure, and cost centers that SAP 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 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 Cost Centers, Business Partners, Materials (Products), Sales Orders in SAP with Interviews, Offers, Users, Approvals 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 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 journal entries and billing documents to a warehouse for finance analytics without loading the ERP.
  • 02 Keep MES and WMS systems aligned with production orders and goods movements.
  • 03 Stream Jobs and Job Postings into a reporting database for requisition, funnel, and time-to-fill dashboards.
  • 04 Export Interviews and Offers to a data warehouse to analyze interviewer load, offer-acceptance rates, and hiring outcomes.

Common sync patterns

Where Smartrecruiters runs payroll: labor cost in the books

Pay and compensation data from Smartrecruiters posts into SAP as labor cost, so finance sees workforce spend without re-entering it by hand.

Where Smartrecruiters is the worker system of record: one employee master

When a worker is hired, moved, or offboarded in Smartrecruiters, the matching employee record in SAP is created, updated, or deactivated, so the business system reflects the workforce as it actually is.

New hires ready to transact in SAP

A new person set up in Smartrecruiters becomes an employee record in SAP in time to submit expenses, enter time, or approve a purchase, without waiting on manual setup.

What you can sync between SAP 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 objects Smartrecruiters objects How this pairing syncs
Production Orders Manufacturing orders exchanged with MES and scheduling systems. 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. Production Orders is specific to SAP and Applications to Smartrecruiters — each maps to any object or custom field on the other side.
Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. 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. Inventory / Stock is specific to SAP and Jobs to Smartrecruiters — each maps to any object or custom field on the other side.
Cost Centers Controlling masters read for mapping costs in finance integrations. Job Postings Job ads and publications pushed to the career site and job boards; created and managed via the job publication endpoints (rate-limited to 2 requests/sec). Cost Centers is specific to SAP and Job Postings to Smartrecruiters — each maps to any object or custom field on the other side.
Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs. Interviews Interview types, timeslots, templates, and scheduled interviews with interviewers and times; created, updated, and read for scheduling and interviewer-load analytics. Business Partners is specific to SAP and Interviews to Smartrecruiters — each maps to any object or custom field on the other side.
Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. 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). Materials (Products) is specific to SAP and Offers to Smartrecruiters — each maps to any object or custom field on the other side.
Sales Orders Order documents written from external channels and read for status and fulfillment. Users Company users (recruiters, hiring managers) with roles, access groups, and activation state; read and written via the User Management API. Sales Orders is specific to SAP and Users to Smartrecruiters — each maps to any object or custom field on the other side.

How changes propagate between SAP 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 Smartrecruiters Sub-second propagation

DetectionSAP notifies Stacksync of record changes through webhook events. Business events via SAP Event Mesh on S/4HANA.

DeliveryEach detected change is written to Smartrecruiters through its API, with automatic retries and rate-limit backoff.

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

Rate-limit considerations

  • SAP: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.
  • 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.
