What is Infor XA? Modules, integrations and alternatives
Infor XA, formerly known as MAPICS XA, is an ERP suite for discrete manufacturers that runs on IBM i (AS/400) systems. It covers MRP, production, order management, purchasing and financials. It remains in use at many established manufacturers, and is often the subject of modernisation planning.
Also known as: MAPICS XA, Infor ERP XA, XA ERP, Infor XA IBM i
Infor XA is a long-established manufacturing ERP originally from the MAPICS family. It supports discrete manufacturing with bills of material, routings, shop orders, MRP, inventory, purchasing, order entry and financial accounting. Names such as MAPICS XA and Infor ERP XA are still used by long-time customers and in searches.
Typical users are mid-sized discrete manufacturers, including automotive suppliers, industrial products, and consumer or electrical goods makers, that adopted it years ago and run it on IBM i servers. For many, the system is stable and deeply customised, which is both its strength and the reason modernisation is difficult.
XA runs on IBM i, with application logic in RPG and related languages and data in the integrated Db2 for i database. Integration is commonly done through database access, data queues, file transfer, and add-on middleware or web service wrappers built by the customer or partners. In many plants XA sits next to warehouse, shop floor and EDI systems built up over years, and decisions often centre on whether to extend, wrap, upgrade or replace it.
Modules and capabilities
Product data management
Item master, bills of material and routings for discrete products.
Master production scheduling and MRP
Planning of requirements and capacity using time-phased logic.
Shop floor control
Shop orders, material issues, labour reporting and completions.
Customer order management
Order entry, pricing, allocation, shipping and invoicing.
Purchasing
Purchase orders, receiving and supplier management.
Inventory management
Stock control across locations, with lot or serial support depending on configuration.
Financials
General ledger, payables, receivables and cost accounting.
Integrations and data access
Db2 for i database
Data resides in the IBM i database, which can be read through standard database connectivity, with care around production load and locking.
RPG customisation
Many sites have custom RPG programs and screens, which define what integration points already exist.
Data queues and file transfer
IBM i data queues, flat files and FTP-style transfers are common integration building blocks.
Web service wrappers
Customers and partners often expose business functions as web services on top of RPG programs to connect modern applications.
EDI and shop floor systems
EDI translators and data collection systems commonly connect through files or database interfaces.
Reporting and analytics
Data is frequently replicated to a separate reporting database or data platform.
Strengths
- Proven, stable platform for plants that have run it for years.
- IBM i is known for reliability and low operational overhead.
- Deep customisation can encode company-specific processes exactly.
- Core MRP and shop floor functions are mature.
- Continuity for sites that want to avoid disruptive replacement.
Limitations
- Dependence on IBM i and RPG skills, which are getting harder to hire in many regions.
- Green-screen style user experience compared with modern web interfaces.
- Integration with cloud and modern tools usually needs custom wrappers.
- Heavy customisation makes upgrades and migration complex.
- Vendor roadmap and support terms for the product should be confirmed directly.
Where AI helps Infor XA users
- - Natural-language reporting over replicated XA data, avoiding load on the production IBM i system.
- - Reading and documenting legacy RPG programs to help teams understand customisations before a migration decision.
- - Generating web service wrappers or API specifications for key business functions, reviewed by IBM i developers.
- - Mapping XA data structures to a target ERP for migration planning, with humans validating the mapping.
- - Private retrieval over manuals, work instructions and quality records using locally hosted models.
Evaluating Infor XA? Check these
- Decide early between extend, wrap, upgrade and replace, and size each option honestly.
- Inventory custom RPG programs, screens and interfaces before any planning.
- Confirm vendor support terms and roadmap for your exact XA release.
- Plan for IBM i skills continuity, including partners and succession.
- Use a replicated data layer for analytics and AI instead of querying production directly.
- If migrating, plan open orders, WIP and inventory cutover separately from master data.

Frequently asked questions
Is Infor XA the same as MAPICS XA?
Yes. MAPICS XA is the earlier name of the product that Infor now calls Infor XA, sometimes Infor ERP XA. Customers and consultants use these names interchangeably, so check the release when reading documentation or job descriptions.
What platform does Infor XA run on?
It runs on IBM i, formerly AS/400 or System i, with data in the integrated Db2 for i database and application logic largely in RPG. Many customers run it on their own hardware, while others use partner-hosted IBM i environments.
Can XA connect to modern cloud tools?
Yes, but usually through added layers: web service wrappers around RPG programs, database connectivity, data queues, file exchange or replication to a data platform. The approach depends on how customised your XA installation is and what skills you have.
Should we migrate off XA?
It depends on business risk, not age alone. Factors include IBM i skill availability, customisation depth, integration needs and vendor support terms. Many sites extend XA with APIs and reporting first, and plan replacement in stages when the cost or risk of staying becomes higher.
Can AI help with an XA estate?
Yes. Useful, lower-risk uses include natural-language reporting on replicated data, documenting legacy RPG, and mapping data for migration. Direct write-back to XA should be limited and approval-gated, and models can be hosted privately where data must stay on premises.
