Why teams connect Dynamics 365 Business Central and SAP S/4HANA

Two ERPs, one set of facts: Stacksync keeps Dynamics 365 Business Central 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 Journals, Dimensions, Payments, Customers in Dynamics 365 Business Central 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 Sync vendor and purchase order data with procurement or AP automation tools.
  • 02 Create sales orders in Business Central automatically from e-commerce or CRM order records, and sync fulfillment status back.
  • 03 Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.
  • 04 Replicate material master and pricing data to e-commerce and quoting tools.

Common sync patterns

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.

Split by function

Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.

What you can sync between Dynamics 365 Business Central 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.

Dynamics 365 Business Central objects SAP S/4HANA objects How this pairing syncs
Sales Orders Order headers and lines created from external channels and read back for fulfillment 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 exchanged with supplier-facing 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.
Dimensions Analytical tags (department, project) that syncs preserve for reporting integrity. Production Orders Manufacturing order status surfaced in planning and operations tools. Dimensions is specific to Dynamics 365 Business Central and Production Orders to SAP S/4HANA — each maps to any object or custom field on the other side.
Payments Customer and vendor payment records reconciled against invoices. Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs. Payments is specific to Dynamics 365 Business Central and Business Partners to SAP S/4HANA — each maps to any object or custom field on the other side.
Customers Core master data synced with CRMs so sales and finance share one customer list. Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs. Customers is specific to Dynamics 365 Business Central and Products / Materials to SAP S/4HANA — each maps to any object or custom field on the other side.
Vendors Supplier master data synced with procurement and AP automation tools. Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility. Vendors is specific to Dynamics 365 Business Central and Billing Documents (Invoices) to SAP S/4HANA — each maps to any object or custom field on the other side.

How changes propagate between Dynamics 365 Business Central 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.

Dynamics 365 Business Central SAP S/4HANA Sub-second propagation

DetectionDynamics 365 Business Central notifies Stacksync of record changes through webhook events. API webhooks (change notifications on subscribed entities) plus polling on lastModifiedDateTime.

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

SAP S/4HANA Dynamics 365 Business Central Interval-based propagation

DetectionStacksync polls SAP S/4HANA for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change timestamps exposed by the OData services.

DeliveryEach detected change is written to Dynamics 365 Business Central through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

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