HR & Identity integration
Keep Workday people data aligned with SAP finance responsibilities.
A hire, transfer or payroll cycle should not leave HR and finance working from different organizational structures. Nexus can move approved Workday changes into the required SAP process, validate cost assignments and return processing results without changing who owns the underlying records.
The problem
Why Workday + SAP needs a governed process
Workday identifies the employee and employment change, while SAP may define the company and cost centre used for accounting. An effective-dated transfer can therefore arrive before its destination cost centre exists, or payroll output can reference an assignment that finance no longer accepts.
Responsibility
How the systems divide responsibility
Workforce authority
Workday
Worker identity, employment status, organizational assignments and approved HR changes.
Finance and ERP authority
SAP
Company and cost-centre definitions, accounting structures and SAP financial documents.
Capabilities
What Nexus orchestrates
Pre-built action groups used in this pattern. Anything else runs through an API, protocol or database step, or Rules + Code, in the same workflow.

Architecture
One governed run across both systems
How work starts
Webhook, schedule or API poll
An employee joins, changes position or leaves, or a payroll output is approved for the next finance step. Future-dated changes remain tied to their effective date.
When a pre-built action does not cover it
Workflow patterns
What teams run across Workday + SAP
01
Hire-to-ERP readiness
Validate the worker's company and cost assignment before preparing the required SAP record or downstream action.
02
Effective-dated transfer
Check that the new organizational and finance mappings are valid for the transfer date. Hold changes that would apply in the wrong period.
03
Payroll output to finance
Validate an approved payroll accounting batch against SAP account and cost-centre rules before submitting the configured posting operation.
04
Cost-centre mismatch review
Compare HR assignments with permitted SAP reference values and route unresolved differences to HR and finance together.
Direction and ownership
Which way each change moves
Workday supplies approved worker and employment changes. SAP provides the finance reference data and processing outcomes needed to validate them. Payroll ownership and posting responsibility are defined for the customer's actual configuration; Nexus coordinates the handoff rather than calculating payroll independently.
Workday SAP
Approved employment changes, cost assignments and payroll-related accounting inputs within scope.
SAP Workday
Permitted finance reference data, validation results and linked processing references.
Control
Approvals and exception handling
Human approval
Unrecognized cost assignments, retroactive changes and payroll batches outside the agreed checks wait for the named HR or finance owner. Accepted records proceed under the approved mapping; rejected records return to correction with their effective date and reason preserved.
Exceptions
- Missing worker cross-references or invalid cost centres hold the affected record for correction.
- Closed-period or SAP validation rejections stop posting and retain the full response.
- Repeated change events are matched to worker, effective date and change reference before another write.
Security, audit and deployment
Every run leaves a reviewable record
- The Workday change or approved batch that initiated the process.
- Effective date, worker cross-reference and finance mappings applied.
- Validation results, rule version and any named approval.
- SAP call outcome and resulting record or posting reference.
Credentials for Workday and SAP are held in the vault and used only by the steps that need them. Role-based permissions decide who can edit, approve and run the workflow. Nexus runs on premises, in private cloud or air-gapped, so the execution record stays inside your deployment boundary. Governance and audit

FAQ
Workday + SAP questions
- Which system owns employee information?
- Workday remains authoritative for the employment fields defined in the design. SAP remains authoritative for its finance structures and documents.
- Does this require copying payroll details into every connected system?
- No. The handoff can limit data to the identifiers, assignments and accounting values required by the agreed process.
- Can it handle future-dated and retroactive changes?
- The workflow can apply effective-date rules and route retroactive changes for review. The permitted destination operations depend on your SAP configuration.
