Why teams connect IBM AS/400 and NetSuite

Give your engineers NetSuite'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 Tax Type, Sales Tax Item, Billing Schedule Customer Subsidiary Relationship, Account from NetSuite into IBM AS/400 and keeps both sides consistent in real time. Whatever NetSuite 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 NetSuite with its validations respected.

Common use cases

  • 01 Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • 02 Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.
  • 03 Expose item and inventory data to internal applications through a continuously synced database table.
  • 04 Mirror journal entries and transaction lines into a warehouse for financial reporting without CSV exports.

Common sync patterns

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the NetSuite interface, limits, and retries.

React to ERP changes

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

Where NetSuite 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 NetSuite

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 NetSuite objects How this pairing syncs
Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Nexus Synced with incremental and full sync per the Stacksync docs. Data queues is specific to IBM AS/400 and Nexus to NetSuite — each maps to any object or custom field on the other side.
Libraries The schema-equivalent containers that scope which files a sync reads. Tax Type Synced with incremental and full sync per the Stacksync docs. Libraries is specific to IBM AS/400 and Tax Type to NetSuite — each maps to any object or custom field on the other side.
Physical files (tables) The Db2 for i tables mapped directly to sync targets. Sales Tax Item Synced with incremental and full sync per the Stacksync docs. Physical files (tables) is specific to IBM AS/400 and Sales Tax Item to NetSuite — 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. Billing Schedule Customer Subsidiary Relationship Synced with incremental and full sync per the Stacksync docs. Logical files (views) is specific to IBM AS/400 and Billing Schedule Customer Subsidiary Relationship to NetSuite — 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. Account Synced with incremental and full sync per the Stacksync docs. Members is specific to IBM AS/400 and Account to NetSuite — 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. Accounting Period Synced with incremental and full sync per the Stacksync docs. Rows / records is specific to IBM AS/400 and Accounting Period to NetSuite — each maps to any object or custom field on the other side.

How changes propagate between IBM AS/400 and NetSuite

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 NetSuite 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 NetSuite through its API, with automatic retries and rate-limit backoff.

NetSuite IBM AS/400 Interval-based propagation

DetectionStacksync polls NetSuite for changes on an incremental schedule, reading only records changed since the previous pass. Polling on lastModifiedDate via SuiteQL or saved searches.

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.
  • NetSuite: API concurrency is governed per account; sync tools queue and throttle requests.
