# What is Infor LN? Modules, integrations and alternatives > Source: https://netray.co/software/infor-ln > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: Manufacturing Software Encyclopedia ## Short answer Infor LN is an enterprise ERP suite for complex manufacturing, project-driven and service-oriented businesses, descended from the Baan product line. It is known for deep support of engineer-to-order, aerospace and defense, industrial machinery and high-tech environments. Customisation is done through Infor LN Tools, with integration through Infor ION and APIs. ## Vendor Infor ## Category erp ## Aliases - Baan - Baan ERP - Baan IV - Baan V - Infor ERP LN - Infor Baan LN ## Overview Infor LN covers manufacturing, order management, project control, service, warehousing, enterprise planning, procurement, quality and finance. It is built for organisations with complicated product structures, long lead times, project-based delivery, or multiple sites and legal entities. Its heritage is the Baan product family, and the name Baan is still widely used when people search for it, particularly for older versions such as Baan IV and Baan V. Typical users are large and upper mid-market manufacturers: aerospace and defense, industrial machinery and equipment, electronics and high-tech, automotive suppliers, and project-driven builders. Functions that matter for these businesses, such as project control, configurable products, subcontracting, multi-company operation and service contracts, are part of the standard model rather than add-ons. Technically, LN runs on a tools layer that provides the session and form framework, the data access layer (DAL) for business logic, and the application database connection. Customers extend it using Infor LN Studio and DAL hooks, and exchange data with other systems through Infor ION, business object documents and application APIs. In a manufacturing stack it often sits beside PLM, MES, warehouse systems and financial consolidation tools, and many sites also run mixed estates with older Baan versions still in service. ## Best For - Engineer-to-order and project-driven manufacturers that need project control, cost and progress tracking in the ERP. - Aerospace and defense suppliers with complex bills of material and traceability requirements. - Industrial machinery and capital equipment builders with configurable products and after-sales service. - Multi-company, multi-site groups that need to run several legal entities on one platform. - Existing Baan customers planning an upgrade or modernisation path within the same product family. ## Modules ### Manufacturing **Description:** Production orders, routings, shop floor control, assembly and make-to-order or engineer-to-order flows. ### Order management **Description:** Sales quotations, orders, schedules, pricing, contracts and shipping. ### Project control (PCS) **Description:** Project structures, budgets, cost and progress tracking and project-linked procurement and production. ### Enterprise planning **Description:** Demand and supply planning, MRP and capacity planning across plants. ### Warehousing **Description:** Warehouse and inventory control with inbound, outbound and storage management functions. ### Procurement **Description:** Purchase orders, schedules, contracts, supplier relationships and subcontracting. ### Service **Description:** Installed base, service orders, contracts and field service handling. ### Finance **Description:** General ledger, accounts payable and receivable, fixed assets, intercompany and consolidation support. ## Deployment Available as vendor-hosted cloud and as customer-managed on-premises installations, with older Baan-era versions still running in many plants under customer management. ## Integrations ### Infor ION and BODs **Detail:** ION carries business object documents between LN and other systems. Publishing and consuming BODs is the standard Infor-sanctioned integration pattern. ### Application APIs and DAL **Detail:** LN exposes business logic through the data access layer, and web-service style access is possible through the platform's integration capabilities. ### Infor LN Studio **Detail:** Custom sessions, reports, scripts and DAL extensions are built with the Studio tooling, which defines how deep customisation is carried out. ### Database layer **Detail:** Data sits in a supported relational database. Direct reads for reporting are common but should follow vendor guidance on table and domain structures. ### EDI and file exchange **Detail:** EDI usually runs through an external translator or integration platform, with LN handling schedules, orders and invoices. ### PLM, MES and warehouse connectors **Detail:** Item, BOM and routing data typically flow from PLM, while production and warehouse events return from MES and automation layers. ## Strengths - Deep functionality for project-driven and engineer-to-order manufacturing, including project control. - Strong multi-company, multi-site and multi-currency model for global groups. - Broad scope within a single product: manufacturing, warehousing, service and finance share a model. - A well-defined tools layer with DAL gives structured, supported customisation points. - Continuity for Baan customers who want to stay in the same product family. ## Limitations - Implementation and customisation can be heavy; skills are specialised and concentrated in a limited consulting pool. - The learning curve and session-based interface can feel dated to users coming from modern web-first systems. - Heavily customised legacy installations can make upgrades slow and require careful impact analysis. - May be more system than a small, simple manufacturer needs. - Documentation and community material is thinner than for the largest ERP brands, and older Baan terminology can confuse searches. ## Alternatives - Infor M3 - SAP S/4HANA - IFS Cloud - Oracle Fusion Cloud ERP - Microsoft Dynamics 365 Finance and Supply Chain - QAD Adaptive ERP ## Ai Opportunities - Natural-language access to orders, project cost, inventory and supply plans, read-only and respecting LN authorisations. - Assisting developers with DAL hooks, scripts and session changes, with generated code reviewed and tested in a non-production company. - Upgrade and Baan-to-LN modernisation analysis: inventorying customisations and mapping them to current standard functions. - Project controllers asking for variance and forecast explanations across cost lines, with the source records shown. - Private retrieval over engineering documents and quality records using locally hosted models for sensitive programmes. ## Selection Tips - Confirm the version and deployment model on offer, since LN is both a current product and a long upgrade history. - Test project control with a real project structure, including change orders and subcontracted work. - Review customisation depth in your current Baan or LN estate before choosing between upgrade and re-implementation. - Ask how your PLM and MES will connect through ION or APIs and who maintains those interfaces. - Check the availability of LN-skilled consultants in your region and time zone before committing. - Plan data migration for open orders, WIP and project balances separately from master data. ## Faq ### Is Infor LN the same as Baan? **Answer:** Infor LN is the current name for the product line that grew out of Baan. Earlier versions were called Baan IV and Baan V. Infor now sells LN, and many documents and job postings still say Baan, so searches often mix both names for what is a continuous product lineage. ### Who uses Infor LN? **Answer:** It is commonly used by larger discrete manufacturers, especially in aerospace and defense, industrial machinery, electronics and project-driven businesses. Its project control, multi-company and complex product support suit engineer-to-order environments better than simple make-to-stock operations. ### How is Infor LN customised? **Answer:** Customisation is done with Infor LN Studio and the tools layer: custom sessions, reports, scripts and DAL hooks that add validation or logic to business objects. The aim is to extend without changing standard code, but heavy customisation still raises upgrade effort. ### How does LN integrate with other systems? **Answer:** The standard route is Infor ION with business object documents, supplemented by application APIs and EDI through an external translator. Direct database reads are used for reporting. The best route depends on whether data flows one way, needs near real time, or requires write-back. ### Can AI work with Infor LN data? **Answer:** Yes. Common patterns include read-only natural-language queries over LN data, developer assistants for DAL and session scripts, and retrieval over related documents. Write operations should be approval-gated, and models can be hosted privately when data may not leave the company network. ## Search terms what is Infor LN, Infor LN modules, Infor LN alternatives, Baan ERP vs Infor LN, Infor LN API, Infor LN Studio, Infor LN DAL, Infor LN project control, Infor LN vs SAP, Infor LN AI integration --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
