Chart of accounts and the dimension model

How Maconomy's chart of accounts and analysis dimensions translate into D365 main accounts, financial dimensions, account structures and advanced rules — including the five-step chart workstream and the false-parity warning.

What you will be able to do

Introduction

Maconomy's chart of accounts and analysis dimensions are the financial backbone of every professional-services firm running the platform. The chart carries natural accounts — revenue, cost, balance sheet — while analysis dimensions (cost centre, department, location, project, activity and others) provide the cross-cutting analytical axes…

The five-step chart workstream

The playbook defines a five-step process for translating the Maconomy chart into D365. Each step has a gate: the next step cannot begin until the previous one is signed off by the finance owner.

Analysis dimensions and the D365 financial dimension model

Maconomy analysis dimensions provide the multi-axis analytical framework that professional-services firms use to slice data by cost centre, department, location, project, activity, client and any number of custom classifiers. A typical Maconomy implementation has four to seven analysis dimensions, with some reaching eight or more.

Account structures and advanced rules

Account structures define which financial dimensions are valid for a given main account range and what values are permitted. They replace Maconomy's combination-validity configuration with a structural, enforceable framework.

The false-parity warning

The playbook states explicitly: copying every source analysis axis into a Finance financial dimension creates unmanageable account combinations and duplicates first-class project, customer, vendor, worker or organisational data.

Dimension defaults and the posting engine interaction

In D365, the main account on a transaction is determined by a posting profile (covered in the Posting Engine chapter). Financial dimension values come from a separate mechanism: Default Dimensions on master records.

Practical dimension design for professional services

A typical Maconomy professional-services firm arrives with these analysis dimensions:

Opening balances and the chart transition

Opening balances must be stated against the target chart and target dimension model. This creates a dependency chain:

Summary

The chart and dimension workstream is the foundation of the financial migration. Every subsequent configuration — posting profiles, project categories, budgets, reports and integrations — depends on it being correct. The five-step process is sequential, gated and finance-owned.
