# Infor LN > Source: https://netray.co/glossary/infor-ln > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: Glossary ## Short answer Infor LN is Infor's enterprise ERP suite for complex discrete manufacturers, descended from Baan IV and Baan V. It is deployed as on-premises LN 10.x or as an Infor CloudSuite edition, and covers manufacturing, warehousing, projects, service and multi-company finance. ## Aliases - Infor ERP LN - ERP LN - ERPLN - LN ERP - SSA ERP LN - LN ## Category infor-ln ## Full Definition Infor LN is the enterprise-tier ERP product in Infor's manufacturing portfolio, aimed at companies with engineer-to-order, project-driven, configured or highly regulated production. Its heritage runs from Baan IV through Baan V to SSA ERP LN, after which Infor continued the line as Infor ERP LN and then the LN 10 series. It sits alongside, not underneath, Infor SyteLine: LN targets multi-entity global complexity, while SyteLine targets faster-moving mid-market discrete manufacturing. The functional core spans item and business partner master data, sales and procurement, Warehousing with its own order and procedure model, manufacturing with routings and shop floor control, Enterprise Planning for supply planning, Project for contract and program work, Service for installed base and field work, and Financials with a multi-company ledger. Aerospace and defense customers lean particularly on project pegging, configuration control and traceability, which is why LN shows up so often in that sector. Technically LN still runs on the Baan platform lineage: sessions identified by codes such as tdsls4101m000, a Tools data dictionary describing every table and field, 3GL and 4GL scripts compiled to pseudo-code and executed by the bshell, porting sets adapting the runtime to each operating system and database, and VRC layering separating standard code from site code. What has changed is the front end and the customization model: a modern web UI and the extension framework rather than modified standard source. Deployment options now split between on-premises or hosted LN 10.x and Infor's cloud editions, where LN is delivered as CloudSuite Industrial Enterprise and the industry variants built on it, such as the aerospace and defense CloudSuite. The cloud editions apply Infor's update cadence, which is the practical reason extensions replaced classic customizations: only code that lives outside the standard layer survives frequent, vendor-controlled updates. ## Why It Matters - LN is one of the few ERP products that natively handles project-pegged inventory and multi-company manufacturing without heavy bolt-ons. - Choosing LN versus SyteLine sets your cost, implementation length and staffing model for a decade, so the selection deserves real analysis. - The extension framework determines whether you can adopt cloud updates or become stuck on a customized on-premises release. - LN's Baan lineage means legacy Baan knowledge is transferable, which changes the calculus on retaining or retraining existing staff. ## In Practice A recurring LN implementation gotcha is treating the enterprise structure as an afterthought. Sites, enterprise units, logistic companies and financial companies must be modeled before master data loads, because changing them later means reconverting inventory, orders and ledger history. Spend the design time up front, and validate the model against a full intercompany transaction before you commit. ## Faq ### Is Infor LN the same as Baan? **Answer:** Infor LN is the continuation of the Baan product line. Baan IV and Baan V were followed by SSA ERP LN after SSA Global acquired the product, and Infor renamed and continued it as Infor LN. The platform concepts, session naming and much of the data model are inherited directly, which is why practitioners still use the two names interchangeably in conversation. ### Who is Infor LN best suited for? **Answer:** LN fits manufacturers with genuine enterprise complexity: multiple plants or legal entities, engineer-to-order or project-driven production, deep configuration requirements, and regulated traceability such as aerospace and defense. Companies with a single plant and straightforward make-to-stock production usually find SyteLine or CloudSuite Industrial faster to implement and cheaper to own over a full lifecycle. ### What is Infor LN and what is its full form? **Answer:** Infor LN is Infor's ERP suite for complex discrete manufacturers. It is also written Infor ERP LN, ERP LN, ERPLN or simply LN ERP. LN is a product name rather than an acronym with an official expansion, so the full form people usually mean is Infor ERP LN, short for Infor Enterprise Resource Planning LN. ### What is the difference between Infor ERP LN and Infor LN? **Answer:** None in practice. Infor ERP LN was the product name used for earlier releases, and the line is now called Infor LN, with the LN 10 series as the current on-premises generation. Both names refer to the same product that descends from Baan, and search results and job posts use them interchangeably. ## Search terms what is infor ln, infor ln erp explained, infor ln meaning, infor ln vs syteline, infor ln 10.7 features --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
