Why teams connect IBM AS/400 and Dynamics 365 Business Central

Give your engineers Dynamics 365 Business Central's data in IBM AS/400: read it with normal queries, write back through the sync, and skip the ERP API entirely.

ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.

Stacksync mirrors Items, Sales Orders, Sales Invoices, Purchase Orders from Dynamics 365 Business Central into IBM AS/400 and keeps both sides consistent in real time. Whatever Dynamics 365 Business Central is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in IBM AS/400 sync back into Dynamics 365 Business Central with its validations respected.

Common use cases

  • Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.
  • Feed shipment and invoice data from the AS/400 into logistics and finance tools in near real time.
  • 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.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the Dynamics 365 Business Central interface, limits, and retries.

React to ERP changes

Updates in Dynamics 365 Business Central arrive as row changes in IBM AS/400, so jobs and triggers can respond as the business record changes.

Where Dynamics 365 Business Central is the HR system of record: people data for internal systems

Worker and org records stay current in IBM AS/400 for provisioning, access, and reporting systems that read from the database.

What you can sync between IBM AS/400 and Dynamics 365 Business Central

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.

IBM AS/400 objects Dynamics 365 Business Central objects
Rows / records The unit of read and write, accessed via SQL or record-level access. Purchase Orders Procurement documents exchanged with supplier-facing systems.
Journals and journal receivers The change log that enables log-based CDC on journaled files. General Ledger Entries Posted financial transactions read for reporting; posted entries are immutable.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Journals Staging records for financial postings created by integrations before posting.
Libraries The schema-equivalent containers that scope which files a sync reads. Dimensions Analytical tags (department, project) that syncs preserve for reporting integrity.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Payments Customer and vendor payment records reconciled against invoices.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Customers Core master data synced with CRMs so sales and finance share one customer list.
