Translating the material master into shared and released products

How SAP's view-based material master — one object extended across plants, sales organisations, and valuation areas — is re-expressed in D365's split model of shared product definition and per-legal-entity released product, with the choices that drives for dimension groups, item groups, and posting profiles.

What you will be able to do

• Describe the organisational extension model of the SAP material master and identify which views map to shared versus released product data in D365
• Explain the difference between a SAP material type and a D365 product type, and their respective roles in account determination
• Map SAP batch management and classification to D365 tracking dimension groups
• Identify the data quality issues in MARM and MBEW that most often block a product migration load

Introduction

The SAP material master is one of the most structurally important objects in any ECC migration, and one of the most misunderstood. On the surface it appears to be a single record per material. In reality it is a collection of views — each view a set of fields maintained at a specific organisational level — joined by the material number.

The SAP material master: views, types, and organisational extensions

A SAP material is defined at the client level in MARA. The MARA record carries the material number, material type (MTART), base unit of measure, material group (MATKL), industry sector (MBRSH), net and gross weight, dimensions, and a handful of cross-plant attributes. MARA has one record per material regardless of how many plants use it.

Units of measure, batch management, and variant configuration

The MARM table holds one conversion record per material per alternative unit. Each record carries the conversion factor (quantity in alternative UoM = factor × quantity in base UoM) and the denominator.

The D365 product model: shared product and released product

Shared product (EcoResProduct). One record per product per environment. Carries the product number, product name, product type (Item or Service), search name, and the product dimension group (if the product has configuration, size, colour, style, or version dimensions).

Product dimension groups and tracking dimensions

D365 uses two classes of dimension group to control how a product is tracked and identified in inventory.

Categories, item groups, and account determination

SAP material groups (MARA-MATKL) serve as procurement and reporting classifiers. In D365, procurement categories (EcoResCategory) play the same role in the purchasing workflow — purchase requisitions and purchase orders can be line-item categorised, and default posting rules can be attached to categories for non-stock procurement.

Summary

The SAP material master is one object with many organisational views. D365 separates product identity (shared product) from company-specific behaviour (released product). Every other aspect of the product data migration — dimension groups, unit conversions, batch management, item groups — builds on that split.
