Request access to the Workday Financial Management web service with Journal Lines domain security
Call Get_Journal_Sources to identify the payroll journal source reference ID used in your tenant
Call Get_Journals with a date range filter and the payroll journal source reference to retrieve posted payroll journal entries
Parse each Journal_Line_Data element for account, cost center, amount, debit/credit indicator, and memo to map to ERP chart-of-accounts
Transmit the normalized journal payload to the ERP system (e.g., via REST or file export) and reconcile net payroll totals against the payroll register before posting
Known gotchas
Workday journals are only available after the payroll run completes and accounting is posted; there is a processing lag between payroll finalization and journal availability
Multi-entity Workday tenants segment journals by company; ensure your query filters by the correct company reference to avoid mixing entities
Workday's chart-of-accounts segment structure (worktags) must be mapped to ERP account codes separately; there is no automatic cross-system COA mapping
