Paycom to Oracle Fusion Data Mapping — Field-Level Crosswalks

Paycom data mapping is the field-level translation between Paycom's single-database HCM/Payroll schema and Oracle Fusion HCM/Payroll's Worker + Assignment + Element + Balance + ACA-record model. Every Paycom Employee field maps to a HcmWorker attribute, every Paycom Paycheck field maps to a Fusion Pay record (PayrollRun + Element Entry + Balance), every Paycom Deduction maps to a Fusion Element Entry, every Paycom 1095-C record maps to a Fusion ACA Employer Reporting record. Syntra ETL ships the paycom data mapping pre-built and refines it during discovery for tenant-specific deduction codes, garnishment rules and locality tax setup.

Paycom Employee maps to Fusion HcmWorker plus a Person record, a WorkRelationship, one or more Assignments and a set of subordinate entities (Address, PhoneNumber, Email, EmergencyContact, NationalIdentifier for SSN). Paycom employee_id is preserved as Fusion's source_system_id for round-trip traceability. Paycom hire_date maps to WorkRelationship date_start. Paycom termination_date maps to WorkRelationship date_end with appropriate termination reason mapping. Paycom employment_status maps to Assignment assignment_status_type with values like ACTIVE_PROCESS, SUSPENDED, INACTIVE_PROCESS. The full paycom data mapping for Employee covers 60+ source fields across 8 Fusion target entities.

Paycom Paycheck is the richest source entity in the paycom data mapping. It maps to Fusion's PayrollRun + Element Entry + Balance + Payment + Costing model. Paycheck header (employee, pay date, pay period, check number) maps to a PayrollRun Action. Each gross-pay line maps to an Element Entry against a Fusion Earnings Element. Each deduction maps to an Element Entry against a Pre-Tax, Voluntary Deduction or Involuntary Deduction Element. Each tax withholding maps to an Element Entry against a Tax Element with the correct jurisdiction. The aggregate YTD/QTD/MTD balances per balance type map to FBDI Payroll Balance Initialization records. Direct-deposit allocations map to Fusion Payment records.

Paycom Deductions split into two Fusion Element classifications. Voluntary pre-tax deductions (401(k), HSA, FSA, Section 125 benefits) map to Pre-Tax Deduction Elements with the correct iterative-calculation flag for tax shielding. Voluntary post-tax deductions (Roth 401(k), union dues, charitable contributions) map to Voluntary Deduction Elements. Garnishments are different — they map to Fusion Involuntary Deduction Elements with full priority order, exemption rules (federal CCPA, state-specific exemptions), and disposable-income calculation rules preserved from the original court order. The paycom data mapping for garnishments preserves the payee-routing instruction so payments continue to land at the right court or agency.

ACA Form 1095-C is mandatory for Applicable Large Employers (50+ FTE). The paycom data mapping for 1095-C covers: Part I (employee identifying information → Fusion ACA Employee record), Part II (offer-of-coverage codes by month → Fusion ACA Coverage Offer per month per employee), Part III (covered individuals for self-insured plans → Fusion ACA Covered Individual records), and the aggregate 1094-C transmittal record (→ Fusion ACA Employer Report). Every monthly code (1A through 1U for offers, 2A through 2I for safe harbors) is preserved with the original month-year so historical 1095-Cs remain re-printable for IRS retrieval through the 3-year retention window.

Yes. Beti — Paycom's employee-driven payroll workflow — generates an audit event per employee per pay cycle: employee verification timestamp, exceptions raised, manager override, final approval. Fusion has no direct equivalent, but the audit metadata still has to be preserved for SOX continuity. The paycom data mapping carries Beti audit events as Fusion extensible flexfield attributes against the PayrollRun Action record. The full Beti audit trail is queryable post-migration through Fusion BI Publisher and OTBI for any pay period from the Paycom history window. Compliance gets the substantiation; the new workflow lives in Fusion's checklist task model.

Maximally granular. The paycom data mapping walks every state, county, city and school district the employer is registered in. Each Paycom tax_jurisdiction maps to a Fusion Tax Reporting Unit with the correct State Tax Authority, Local Tax Authority and jurisdiction-specific calculation rules. Locality-specific quirks — NYC resident tax for non-resident PA workers, Philadelphia wage tax for non-resident employees, San Francisco payroll expense tax — are explicitly modeled, not approximated. Every withholding YTD balance is mapped per jurisdiction so quarterly 941 and state SUI filings reconcile to the penny across both systems during parallel run.

Every paycom data mapping is documented as a signed mapping specification: source entity, source field, source data type, target entity, target field, target data type, transformation rule, default value if source is null, validation rule, business owner sign-off. The mapping spec is generated automatically from the Syntra ETL crosswalk configuration so it stays in sync with what actually runs. The signed mapping spec ships in the cutover sign-off pack to internal audit. When auditors ask why a particular Paycom deduction code ended up in a particular Fusion Element classification, the answer is in the mapping spec with the date and the signature of the payroll director who signed it.
