Why teams connect IBM AS/400 and SAP Business One

Give your engineers SAP Business One'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 Deliveries, Journal Entries, Warehouses, Price Lists from SAP Business One into IBM AS/400 and keeps both sides consistent in real time. Whatever SAP Business One 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 SAP Business One with its validations respected.

Common use cases

  • 01 Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
  • 02 Keep customer and item files aligned with an ecommerce platform or modern ERP during phased modernization.
  • 03 Two-way sync of business partners between SAP Business One and a CRM so sales edits and finance records converge on one customer master.
  • 04 Create sales orders in Business One from e-commerce platforms and sync delivery and invoice status back to the storefront.

Common sync patterns

React to ERP changes

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

Where SAP Business One 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.

Controlled write-back

Choose exactly which tables and fields may flow from IBM AS/400 back into SAP Business One, keeping the ERP authoritative.

What you can sync between IBM AS/400 and SAP Business One

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 SAP Business One objects How this pairing syncs
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Business Partners Combined customer, vendor, and lead master records; the anchor object for most syncs. Physical files (tables) is specific to IBM AS/400 and Business Partners to SAP Business One — each maps to any object or custom field on the other side.
Logical files (views) Indexed or filtered views over physical files, usable as read sources. Items Product master data including inventory levels, aligned with e-commerce and warehouse systems. Logical files (views) is specific to IBM AS/400 and Items to SAP Business One — each maps to any object or custom field on the other side.
Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Sales Orders Order documents with header and line structure created from external channels. Members is specific to IBM AS/400 and Sales Orders to SAP Business One — each maps to any object or custom field on the other side.
Rows / records The unit of read and write, accessed via SQL or record-level access. A/R Invoices Billing documents synced outward for CRM visibility and payment tracking. Rows / records is specific to IBM AS/400 and A/R Invoices to SAP Business One — each maps to any object or custom field on the other side.
Journals and journal receivers The change log that enables log-based CDC on journaled files. Purchase Orders Procurement documents exchanged with supplier-facing tools. Journals and journal receivers is specific to IBM AS/400 and Purchase Orders to SAP Business One — each maps to any object or custom field on the other side.
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Deliveries Fulfillment documents read to update shipment status in external systems. Data queues is specific to IBM AS/400 and Deliveries to SAP Business One — each maps to any object or custom field on the other side.

How changes propagate between IBM AS/400 and SAP Business One

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.

IBM AS/400 SAP Business One Sub-second propagation

DetectionChanges in IBM AS/400 are captured at the source via change data capture — no polling loop against its API. Journal-based CDC by reading journal receivers on journaled files.

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

SAP Business One IBM AS/400 Interval-based propagation

DetectionStacksync polls SAP Business One for changes on an incremental schedule, reading only records changed since the previous pass. Polling on update timestamps.

DeliveryEach detected change is applied to IBM AS/400 as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.
