Why teams connect Dynamics 365 Business Central and SAP

Two ERPs, one set of facts: Stacksync keeps Dynamics 365 Business Central and SAP 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, General Ledger Entries, Journals, Dimensions in Dynamics 365 Business Central with Cost Centers, Business Partners, Materials (Products), Sales Orders in SAP 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

  • Mirror items and inventory levels into external channels so stock data stays current outside the ERP.
  • Replicate GL entries and dimensions into a SQL database for financial reporting without giving analysts ERP logins.
  • Replicate journal entries and billing documents to a warehouse for finance analytics without loading the ERP.
  • Keep MES and WMS systems aligned with production orders and goods movements.

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.

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.
