Item master, product variants, and dimension groups

How to translate LN's single multi-view item record — with its item types, item groups, item-site and item-warehouse data, and generic-item configurator — into D365 shared products, released products per legal entity, product dimension groups, and product categories.

What you will be able to do

• Name LN's item types and explain how each maps to a D365 product type or default order type
• Explain why an LN item becomes a shared product released into each legal entity in D365
• Describe LN item-site and item-warehouse data and their D365 equivalents
• Map LN unit sets and conversion factors to D365 UoM conversions
• Explain how LN generic items and the product configurator map to D365 constraint-based configuration or product variants

Introduction

The item master is the foundation on which all supply-chain and manufacturing processes stand. Get it wrong and every downstream flow — BOMs, purchase orders, production orders, inventory positions — is built on incorrect assumptions. In LN the item is a single record with multiple views;

LN item types and the item-group split

The item group in LN is a multi-purpose classification that simultaneously controls: IMS posting-account resolution (which GL accounts receive inventory receipts, issues, and adjustments for this item), MRP parameters (planning horizons, lot sizes, safety stock), and operational classification (ABC analysis, cycle count frequency).

Item-site and item-warehouse data

LN stores planning and stocking parameters at three levels: the base item record, the item-site record, and the item-warehouse record. This layered structure allows the same item to have different reorder points, lead times, costing methods, and procurement sources across different sites and warehouses in the same Logistic Company.

Unit sets, conversion factors, and item codes

LN groups related units of measure into unit sets and defines the conversion factors between them. A typical unit set for a discrete mechanical item might define: kg (the stocking unit), each (sales and purchase unit), and pallet (goods-receipt unit), with the conversion factors between them.

Generic items and the product configurator

LN's generic item is a template item without a fixed BOM or routing. When a customer places an order for a generic item, a product configurator session generates an order-specific set of specifications — typically a variant code, an order-specific BOM, and an order-specific routing — from a predefined configuration model.

Summary

The item master migration is deceptively broad. It is not just about moving item records — it is about correctly mapping LN's multi-purpose item group into D365's distributed object model, translating per-site and per-warehouse parameters into site-scoped default order settings, and deciding whether LN generic items become…
