How RJR Designs HCM Integrations: From Boomi to Production

A manufacturer goes live on UKG Pro. Three weeks later, the payroll team is spending six hours every pay period manually reconciling labor cost data between UKG and their ERP. The integration was built, it runs on schedule, but the field mappings don't account for the client's cost center structure, so the numbers land in the wrong buckets and someone has to fix them by hand.

This is the most common integration failure pattern RJR sees: an integration that works technically but doesn't work operationally. The data moves. It just moves to the wrong place.

How RJR approaches integration design

Every integration engagement starts with a current-state assessment before any development work begins. RJR documents the source system's data model, the target system's expected format, and the transformation logic required to map one to the other accurately. For payroll-adjacent integrations, that assessment includes a field-by-field review of how cost centers, job codes, pay components, and deduction codes are represented in each system.

RJR's primary middleware platform is Dell Boomi. Boomi's pre-built connectors support most major ERP and HRIS platforms, and its process-library architecture allows reuse of transformation logic across similar integrations. For clients running SAP, Sage, QuickBooks, IFS, Acumatica, Viewpoint, COINS, NCR Aloha, or Toast, RJR has established connector patterns that reduce build time and eliminate the mapping errors that come from starting from scratch.

Common integration types RJR builds

• Payroll-to-ERP: labor cost posting, general ledger allocation, cost center reconciliation
• Time-and-attendance-to-payroll: shift data, overtime calculations, paid time off accruals
• Benefits-to-carrier: eligibility files to insurance carriers, 834 transaction sets, real-time enrollment updates
• HCM-to-background-screening: new hire data transfer, status callbacks, adverse action workflows
• POS-to-scheduling: demand signal feeds from point-of-sale systems for retail and food service scheduling
• ERP-to-HCM: new-hire position data, job code synchronization, cost center updates

UAT discipline

RJR does not sign off on an integration until it has been tested against real payroll data, not sample records. Test records miss the edge cases that real payroll exposes: employees with multiple rate changes in a single period, retroactive adjustments, garnishments that interact with overtime calculations, mid-period terminations. UAT with real data surfaces these before go-live. UAT with sample data surfaces them in production.

Every integration RJR delivers includes field-mapping documentation that travels with the engagement: source field, target field, transformation rule, and known exception handling. When the client's ERP is upgraded six months later and a field name changes, the documentation tells the team exactly where to look.

What ongoing integration management looks like

Integrations break. API versions change, ERP upgrades modify data structures, and payroll platform updates sometimes alter field formats without notice. RJR offers post-go-live integration monitoring as part of managed services engagements, catching failures before the next payroll run, not after.

RJR has built integrations across more than 100 HCM implementations. The firm knows which platform version combinations have known connector issues and which transformation patterns require extra validation logic. That pattern library is what separates an integration that works on day one from one that works indefinitely.
