# Arena PLM and Oracle NetSuite: syncing items, BOMs and ECOs > Source: https://netray.co/stack/arena-plm-oracle-netsuite > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: ERP Stack ## Short answer Arena is the system of record for engineering items, BOMs and change orders, and NetSuite is the system of record for purchasing, inventory and production. The usual pattern is that a released item or BOM revision in Arena is pushed to NetSuite through a connector or middleware, so purchasing and manufacturing never work from a draft. ## Erp Oracle NetSuite ## Erp Key netsuite ## On Prem false ## Product Arena PLM ## Vendor Arena (a PTC company) ## Category PLM ## Integration **Method:** PLM-to-ERP connector or middleware (BOM and ECO sync) **Detail:** Arena publishes integration guidance for sending released item and BOM data to an ERP. For NetSuite, teams typically use a connector or an integration platform that calls Arena's REST API on one side and NetSuite's SuiteTalk or RESTlets on the other. Which route fits depends on your volume and who maintains it; treat any given mapping as a project, not a switch. **Method:** Release-triggered push **Detail:** The sync is normally keyed on the ECO release status in Arena. When the change order is implemented, the new item revision and BOM are written to NetSuite as inventory or assembly items and bill of materials revisions, with an effective date taken from the ECO. ## Data Flows **From:** Arena **To:** NetSuite **Data:** Item master: number, description, UoM, category, lifecycle status **Trigger:** Item or ECO released in Arena **From:** Arena **To:** NetSuite **Data:** BOM structure with quantities, reference designators and effectivity **Trigger:** ECO implemented **From:** Arena **To:** NetSuite **Data:** Approved manufacturer and vendor parts for purchasing **Trigger:** Sourcing record approved **From:** NetSuite **To:** Arena **Data:** Item numbers or cost and inventory status where the design reads them back **Trigger:** Scheduled or on request **From:** Arena **To:** NetSuite **Data:** ECO number and revision as reference on the item or BOM revision **Trigger:** ECO release ## Setup ### Decide item ownership **Detail:** Agree which fields Arena owns (number, description, revision, BOM) and which NetSuite owns (costing, reorder points, preferred vendor, locations). Write it down before building anything. ### Align the item numbering scheme **Detail:** Make the Arena item number the NetSuite item name or a unique external ID, so the sync can upsert instead of creating duplicates. ### Map item categories and types **Detail:** Map Arena categories to NetSuite item types (inventory, assembly, non-inventory) and to NetSuite item classes or custom fields. ### Map units of measure **Detail:** Confirm every Arena UoM exists in a NetSuite units type and that purchase, stock and sale units agree. ### Build or configure the connector **Detail:** Set up the integration user and role in NetSuite, token-based authentication, and the Arena API credentials. Keep a sandbox NetSuite account for testing. ### Define the BOM revision strategy **Detail:** Decide whether each ECO creates a new BOM revision with an effective date or overwrites the current one, and how component substitutions are handled. ### Pilot one product family **Detail:** Release a real ECO for a small assembly, compare Arena and NetSuite BOMs line by line, and fix mapping gaps. ### Add monitoring **Detail:** Log every sync call with the ECO number and result, and alert someone when a release fails to land in NetSuite. ## Pitfalls - Duplicate items when the Arena number and the NetSuite item name differ by a prefix, a trailing space or case. - Revision handling: a BOM pushed without an effective date goes live immediately and can disrupt open work orders. - Unit of measure mismatches cause quantities to be off by a pack size without any error being raised. - Partial failures: a parent assembly is created but a child component item failed, leaving an incomplete BOM. - Fields edited directly in NetSuite are overwritten on the next sync if ownership was never agreed. - Sandbox refreshes wipe tokens and integration roles, so a working test setup silently stops. ## Ai Layer ### Release reconciliation **Description:** A private assistant reads Arena BOMs and NetSuite BOM revisions, and lists differences in components, quantities or effective dates after each ECO, so engineering reviews exceptions instead of comparing screens. ### Failed sync triage **Description:** It reads the integration log, explains in plain language why an ECO did not land (missing UoM, unknown item type, locked record) and drafts the fix for a person to approve. ### Where-used questions **Description:** Buyers and planners ask which open purchase orders or work orders use a component that an ECO is about to obsolete, with the NetSuite query shown. ### ECO impact summaries **Description:** For a released change, it drafts a summary of affected open orders and on-hand stock for the change board, grounded in both systems. ## Alternatives - For a small catalogue, manual BOM entry in NetSuite with a controlled spreadsheet release process may be enough. - If your CAD tool is the starting point, a CAD BOM integration such as OpenBOM may be simpler than a full PLM. - A general integration platform you already run may be cheaper than a dedicated connector, at the cost of building the mappings yourself. ## Faq ### Does Arena write directly into NetSuite? **Answer:** Not on its own in most projects. Teams use a connector or an integration platform that reads released data from Arena's API and writes items and BOMs to NetSuite. Ask the vendor or your integrator exactly which route they support, and what is configuration versus custom work. ### Which system should own the BOM? **Answer:** Usually Arena owns the engineering BOM and NetSuite holds the manufacturing copy used for planning and work orders. Keep one direction of change for structure fields, and let NetSuite own costing and supply data. ### How are engineering changes handled? **Answer:** The ECO release in Arena is the trigger. The new revision and effectivity are sent to NetSuite so open work orders keep their old revision while new ones use the new one, provided you configure revisions rather than overwrite. ### Can AI help here without sending data to a public service? **Answer:** Yes. A model hosted privately can read exports or read-only queries from both systems to flag mismatches and explain sync errors. Any change to NetSuite or Arena should stay a human-approved step. ## Source https://www.houseblend.io/articles/en/guide-integration-arena-netsuite ## Search terms arena plm netsuite integration, arena plm netsuite bom sync, plm to netsuite eco release, netsuite bom revision from plm, arena netsuite item master, sync engineering bom to netsuite --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
