Why teams connect QAD ERP and SAP S/4HANA

Two ERPs, one set of facts: Stacksync keeps QAD ERP and SAP S/4HANA consistent in real time, whether they split the business or one is replacing the other.

Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.

Stacksync syncs Purchase orders, Work orders, Inventory balances, General ledger transactions in QAD ERP with Deliveries, Journal Entries, Customer / Supplier Roles, Production Orders in SAP S/4HANA bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.

Common use cases

  • 01 Replicate inventory and work-order data into a warehouse for supply chain analytics across plants.
  • 02 Push EDI orders from trading partners into QAD as sales orders.
  • 03 Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.
  • 04 Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.

Common sync patterns

Two-tier roll-up

Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.

Migration in parallel

When one system is replacing the other, run both fully live during the transition and cut over without a data freeze.

Shared master data

Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

What you can sync between QAD ERP and SAP S/4HANA

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.

QAD ERP objects SAP S/4HANA objects How this pairing syncs
Sales orders Demand records written in from EDI or e-commerce and read out for status Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Purchase orders Procurement documents mirrored to planning and finance systems Purchase Orders Procurement documents shared with supplier portals and spend-management tools. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Inventory balances Stock levels by site and location, synced for multi-plant visibility Journal Entries Financial postings read into warehouses and consolidation tools for reporting. Inventory balances is specific to QAD ERP and Journal Entries to SAP S/4HANA — each maps to any object or custom field on the other side.
General ledger transactions Financial postings exported for consolidated reporting Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. General ledger transactions is specific to QAD ERP and Customer / Supplier Roles to SAP S/4HANA — each maps to any object or custom field on the other side.
Items Item master records shared with CRM, e-commerce, and planning systems Production Orders Manufacturing order status surfaced in planning and operations tools. Items is specific to QAD ERP and Production Orders to SAP S/4HANA — each maps to any object or custom field on the other side.
Customers Account records kept consistent with the sales team's CRM Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs. Customers is specific to QAD ERP and Business Partners to SAP S/4HANA — each maps to any object or custom field on the other side.

How changes propagate between QAD ERP and SAP S/4HANA

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

QAD ERP SAP S/4HANA Interval-based propagation

DetectionStacksync polls QAD ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling on the API surface.

DeliveryEach detected change is written to SAP S/4HANA through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • QAD ERP: Subject to instance capacity and the platform's API limits.
  • SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.
