Why teams connect IBM AS/400 and Workday

Work with Workday's financial data straight from IBM AS/400: read it with ordinary queries, write to it from your own code, and let Stacksync keep both sides consistent.

Engineers need finance data more often than finance systems make it easy to get: for internal tools, reporting services, or logic that reacts to invoices and payments. Working through the vendor API means rate limits, pagination, and glue code that has to be maintained forever.

Stacksync mirrors Positions, Compensation, Time Off and Absence, Payroll Results from Workday into Libraries, Physical files (tables), Logical files (views), Members in IBM AS/400 and keeps the two in sync bi-directionally and in real time. Your services read finance records with normal queries against IBM AS/400, and rows your code writes or updates flow back into Workday with validation, so the finance system stays the system of record.

Common use cases

  • Replicate worker, organization, and compensation data into a secured database for people analytics without giving analysts tenant access.
  • Push completed payroll results into a finance system or data warehouse each pay cycle.
  • Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.

Write back safely

Updates written to the synced tables in IBM AS/400 propagate into Workday, so automations can create or correct finance records without custom integration code.

React to financial events

Changes in Workday appear in IBM AS/400 as row changes, so you can trigger downstream logic with the database tooling you already use.

Query finance data like any other data

Customers, invoices, and payments from Workday live in IBM AS/400 as regular tables or collections your team can join, index, and query.

What you can sync between IBM AS/400 and Workday

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.

IBM AS/400 objects Workday objects
Libraries The schema-equivalent containers that scope which files a sync reads. Payroll Results Completed pay data exported to finance and benefits systems.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Suppliers Workday Financials vendor records aligned with procurement tools.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Customers and Invoices Financials receivables objects synced for billing visibility where Workday Financials is used.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Journal Entries Accounting entries imported from external subledgers into Workday Financials.
Rows / records The unit of read and write, accessed via SQL or record-level access. Custom Reports (RaaS) Tenant-defined reports exposed as web service endpoints, often the practical read surface for syncs.
Journals and journal receivers The change log that enables log-based CDC on journaled files. Workers The central HCM record covering employment, job, and personal data; the anchor of most syncs.

How the IBM AS/400 and Workday connectors work

IBM AS/400

Integration surface
SQL over JDBC/ODBC to Db2 for i (for example the JTOpen/jt400 driver), alongside native record-level access
Authentication
IBM i user profile credentials (database credentials)
Change detection
Journal-based CDC by reading journal receivers on journaled files; polling as a fallback
Capabilities
read · write · CDC
Rate limits
Bounded by system resources and subsystem configuration rather than an API quota.

Workday

Integration surface
SOAP Workday Web Services (WWS), a REST API, and Reports-as-a-Service (RaaS) endpoints for custom reports
Authentication
OAuth 2.0 for the REST API; integration system users with WS-Security or certificate-based auth for SOAP
Change detection
Polling, including transaction-log criteria on SOAP operations to fetch objects changed since a given moment; no general webhook surface
Capabilities
read · write
