# Infor ION Scripting and ETL: Transformation Options Explained

## Short answer

ION is an integration and messaging layer, not a general ETL tool. Transformation happens in mappings inside document flows (field mapping, functions, conditions) and in Data Lake ingestion; for heavy or multi-source ETL you normally pair ION with a dedicated tool. Scripting capabilities depend on the ION component and version.

## Kind

how-to

## System

infor-os

## Erp

Infor ION (Infor OS)

## Module

ION Connect / Mapping / Data Lake

## Query

infor ion scripting

## Alternate Queries

- infor ion etl tool
- infor ion data transformation
- infor ion mapping functions

## Applies To

Infor ION in Infor OS (cloud and on-premise). Capabilities of the mapper and scripting vary by version; confirm in the ION documentation.

## Steps

### How to approach transformation in ION

**Items:**

- Clarify the need: moving a business document between applications (ION Connect), loading data to the Data Lake, or heavy batch ETL. Each uses a different part of the platform.
- For application-to-application flows, open ION Desk and the Connect area, and build a document flow between connection points.
- Add a mapping between the source and target BOD or document and map fields one to one first.
- Use the mapper's functions and conditions for transformations such as concatenation, lookups or defaults, and use script steps only where your version supports them.
- Test with a real sample document through the monitor; compare the output with the target's expected schema.
- For analytics, send documents to the Data Lake and transform there or in the analytics layer rather than in the flow.
- For high-volume or complex joins, use a dedicated ETL tool and use ION only for event delivery.
- Version and document each mapping; changes in the ERP's BOD structure after an upgrade will break them.

## Sections

### Where logic lives in an ION flow

**Body:**

A document flow moves BODs (Business Object Documents) between connection points. The mapping between two document types is where you shape data: renaming, restructuring, computing values and filtering.

Keep mappings simple and push business rules into the source or target application where possible, because logic hidden in a mapping is hard to find during an upgrade.

### ION versus a real ETL tool

**Body:**

ION is good at event-driven messaging with guaranteed delivery and monitoring. It is not designed for large set-based transformations, slowly changing dimensions or multi-gigabyte batch loads.

A realistic pattern is ION for operational integration and the Data Lake for landing data, with transformation in the analytics layer or in a tool such as an external ETL service for heavy lifting.

### Calling out to code

**Body:**

When a mapping cannot express a rule, the usual alternatives are an API call through the ION API gateway to a small service you own, or a custom extension in the ERP. This keeps code testable and versioned outside the mapper.

Secure such calls with service accounts and the .ionapi credential, and log failures where operations staff will see them.

## Pitfalls

- Treating ION as a batch ETL engine and overloading flows with large payloads.
- Burying business rules in mappings with no documentation.
- Not retesting mappings after an ERP upgrade changes the BOD structure.
- Skipping the monitor: failed documents sit in error queues unnoticed.
- Embedding credentials in mappings or flows instead of using managed service accounts.

## Ai Angle

An assistant can read your BOD definitions and mappings and explain, in plain language, what a flow does or why a document failed, which is slow to do by hand. Netray builds such assistants on private models next to your Infor environment so integration definitions stay in house. It does not replace your integration monitoring.

## Faq

### Does Infor ION support scripting?

**Answer:** ION offers mapping functions and, depending on component and version, extension points. For complex logic most teams call a service through the ION API. Check your version's documentation for what the mapper supports.

### Is ION an ETL tool?

**Answer:** Not in the classic sense. It is an integration and messaging platform. For bulk transformation use the Data Lake and analytics tooling or an external ETL tool.

### Where do I see failed documents?

**Answer:** In the ION monitoring area, which lists documents and their status per flow and connection point, allowing you to inspect errors and resubmit.

### Can I use ION on premise?

**Answer:** Yes, ION is available for on-premise Infor OS deployments, though features and update cadence differ from the cloud edition. Confirm with Infor.
