Why teams connect SAP S/4HANA and Workday

Keep Workday and SAP S/4HANA agreeing on customers, invoices, and balances, whether they split the finance workload or one is replacing the other.

A dedicated finance tool and an ERP end up side by side for practical reasons: a subsidiary runs lighter software than headquarters, billing runs in a specialist system while the enterprise system holds the wider view, or the company is mid-migration and both are live. Whatever the split, the two systems describe overlapping customers and transactions, and that overlap drifts without a live connection.

Stacksync syncs Organizations, Positions, Compensation, Time Off and Absence in Workday with Deliveries, Journal Entries, Customer / Supplier Roles, Production Orders in SAP S/4HANA in real time and in both directions. You decide which system wins on which field, and every change made in one is reflected in the other within seconds instead of at the next batch run.

Common use cases

  • Sync worker records from Workday into IT and identity systems so hires, transfers, and terminations provision access automatically.
  • Replicate worker, organization, and compensation data into a secured database for people analytics without giving analysts tenant access.
  • Replicate material master and pricing data to e-commerce and quoting tools.
  • Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.

Migration without a hard cutover

When one system is replacing the other, run both in parallel with records matching until the switch is complete.

One customer and vendor master

Where both systems keep records of the same organizations, corrections made in either propagate to the other.

Subsidiary to headquarters

Where Workday serves a business unit and SAP S/4HANA is the group system, transactions and customer records roll up continuously, so consolidation starts from live data.
