Why teams connect Dun And Bradstreet and IBM AS/400

Treat Dun And Bradstreet like part of your database: its records live in IBM AS/400 as real tables, and writes in either place sync to the other in seconds.

Dun And Bradstreet is a read-only source: Stacksync reads its data in real time and delivers it into IBM AS/400, so IBM AS/400 always reflects the current state of Dun And Bradstreet — without exports, scripts, or schedulers.

Product and engineering teams constantly need CRM data, and the CRM API is a poor way to get it: rate limits, pagination, custom objects, and integration code that breaks when an admin renames a field. What they actually want is the data in IBM AS/400, where it can be queried and joined like everything else.

Common use cases

  • 01 Sync the D&B corporate family tree (parent and subsidiary DUNS) into the CRM so ABM and territory owners see full account hierarchies and roll pipeline up to the global ultimate.
  • 02 Build target-account lists with Criteria Search and land the resulting DUNS plus firmographics in a database for outbound and TAM analysis.
  • 03 Expose AS/400 order, inventory, and item master data to modern SaaS tools without rewriting green-screen applications.
  • 04 Use journal-based change capture to replicate IBM i data into a cloud warehouse for reporting.

Common sync patterns

Internal tools without API code

Back-office apps read and write the synced tables; Stacksync handles the Dun And Bradstreet API, limits, and retries.

Trigger workflows from CRM changes

Field and stage updates in Dun And Bradstreet arrive as row changes in IBM AS/400, ready to drive jobs and notifications.

Query the CRM like a database

Accounts, contacts, and custom objects from Dun And Bradstreet become tables in IBM AS/400 you can join with application data directly.

What you can sync between Dun And Bradstreet and IBM AS/400

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.

Dun And Bradstreet objects IBM AS/400 objects How this pairing syncs
Monitoring Notifications Change notices for a registered portfolio of DUNS; read-only feed pulled from the notifications endpoint (retained ~60 days) or delivered as bundled push. Data queues Program-to-program messaging objects sometimes used to hand events off to integrations. Monitoring Notifications is specific to Dun And Bradstreet and Data queues to IBM AS/400 — each maps to any object or custom field on the other side.
Company Information (Data Block) Core firmographics for a D-U-N-S Number - legal name, addresses, industry codes, employees, sales, status. Retrieved read-only via the Enrich endpoint; blocks come in levels L1-L4. Libraries The schema-equivalent containers that scope which files a sync reads. Company Information (Data Block) is specific to Dun And Bradstreet and Libraries to IBM AS/400 — each maps to any object or custom field on the other side.
Principals & Contacts (Data Block) Company officers, executives, and contacts tied to a D-U-N-S Number; read-only enrichment used to populate CRM contact and account-owner fields. Physical files (tables) The Db2 for i tables mapped directly to sync targets. Principals & Contacts (Data Block) is specific to Dun And Bradstreet and Physical files (tables) to IBM AS/400 — each maps to any object or custom field on the other side.
Company Hierarchy & Connections (Family Tree) Parent, subsidiary, branch, and global-ultimate DUNS relationships; read-only, used to build account hierarchies and corporate-family rollups. Logical files (views) Indexed or filtered views over physical files, usable as read sources. Company Hierarchy & Connections (Family Tree) is specific to Dun And Bradstreet and Logical files (views) to IBM AS/400 — each maps to any object or custom field on the other side.
Financial Strength & Risk Insight (Data Block) D&B risk and credit signals - D&B Rating, PAYDEX, Failure Score, Delinquency Score, Viability - keyed by D-U-N-S Number; read-only. Members Sub-partitions of files in legacy applications, flattened or selected during syncs. Financial Strength & Risk Insight (Data Block) is specific to Dun And Bradstreet and Members to IBM AS/400 — each maps to any object or custom field on the other side.
Identity Resolution (Match / cleanseMatch) Sends a company name and address and returns ranked candidate DUNS with confidence codes and a MatchGrade; read-only scored match, not an exact lookup. Rows / records The unit of read and write, accessed via SQL or record-level access. Identity Resolution (Match / cleanseMatch) is specific to Dun And Bradstreet and Rows / records to IBM AS/400 — each maps to any object or custom field on the other side.

How changes propagate between Dun And Bradstreet and IBM AS/400

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.

Dun And Bradstreet IBM AS/400 Interval-based propagation

DetectionStacksync polls Dun And Bradstreet for changes on an incremental schedule, reading only records changed since the previous pass. Polling via D&B Monitoring - register a portfolio of DUNS and pull change notices from the notifications endpoint (retained ~60 days).

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

IBM AS/400 Dun And Bradstreet 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.

DeliveryDun And Bradstreet does not accept inbound record writes, so this direction carries requests rather than records: Dun And Bradstreet's output flows back as field updates on the originating IBM AS/400 records.

Rate-limit considerations

  • Dun And Bradstreet: Per-contract transactions-per-second cap plus weekly/monthly/yearly quotas; exceeding TPS returns HTTP 429 with error 0045/0046 (0047 on spike arrest). Quotas reset on UTC boundaries.
  • IBM AS/400: Bounded by system resources and subsystem configuration rather than an API quota.
