Why teams connect SAP S/4HANA and ServiceNow

Bridge the tools people work in and the system the business runs on: real-time, two-way sync between ServiceNow and SAP S/4HANA.

The ERP holds the records the business is run on, and it is rarely where day-to-day work happens. ServiceNow is closer to the work, and the two often need the same facts about the same people, organizations, and transactions. Bridging them by hand, or by nightly file transfer, leaves each side out of date for hours at a time.

Stacksync syncs Knowledge Articles, Custom Tables, Incidents, Change Requests in ServiceNow with Business Partners, Sales Orders, Purchase Orders, Products / Materials in SAP S/4HANA bi-directionally and in real time, with field-level mapping and rules for which system wins on conflict. Changes made where the work happens reach the system of record within seconds, and the reverse.

Common use cases

  • Keep CMDB configuration items aligned with asset inventories and cloud resource databases
  • Sync sys_user records with the HR system or identity provider so assignment groups stay accurate
  • Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.
  • Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.

Where ServiceNow faces customers and SAP S/4HANA carries account records

Order, invoice, or account status from SAP S/4HANA appears alongside the customer in ServiceNow, so front-line teams answer from live data.

Where SAP S/4HANA is the HR or people system of record

Worker and organization data from SAP S/4HANA stays current in ServiceNow, so the tools people use daily reflect the org as it actually is.

Master data corrections travel

A customer, supplier, or contact detail corrected in either system updates the other, ending duplicate maintenance.
