Chart of accounts, dimensional analysis fields and account structures
How Plex's thinly documented chart of accounts and dimensional analysis fields translate into D365 main accounts, financial dimensions, account structures and advanced rules — and why the topology decision made in the organisation chapter determines the entire design.
Design a D365 chart of accounts from a Plex GL export rather than from configuration documentation
Translate Plex's dimensional analysis fields into D365 financial dimensions using the correct dimension type
Build account structures that enforce dimension requirements by account range, within the eleven-segment ceiling
State the dependency between the site/plant topology decision and the chart of accounts design
Introduction
Plex ERP's Financial Management module provides a general ledger, accounts payable and receivable, fixed assets, budgeting, and cash management — the same functional surface every manufacturing ERP offers.
The Plex source: what is confirmed and what is not
Rockwell Automation's Financial Management product page confirms the following capabilities at module level:
The D365 target: main accounts, dimensions, and account structures
D365 Finance models the chart of accounts through three interlocking constructs. Understanding all three is essential before attempting the Plex translation, because the source side is too thinly documented to drive the design on its own — the target model must be understood independently.
The topology dependency: why finance cannot start alone
Legal entity per plant means intercompany accounting is required between plants, consolidation is required for group reporting, and each entity can have different fiscal calendars, currencies, and ledger configurations.
The discovery method: building a chart of accounts from evidence
Because Plex publishes no account-structure reference, the D365 chart of accounts must be designed from a GL export extracted from the client's live Plex tenant. The method:
The difference between a dimension and a reporting attribute
Not every Plex analysis field should become a D365 financial dimension. The distinction matters:
Multi-site reporting: consolidation versus dimensional filtering
Plex's Financial Management page describes "ad hoc analysis across multiple manufacturing locations" — a form of multi-site reporting. How this translates depends, again, on the topology decision:
Knowledge check
Summary
Plex's chart of accounts and dimensional analysis fields are real — they drive every transaction in the platform — but they are not publicly documented at a schema level. The design of the D365 chart of accounts and financial dimensions must therefore be evidence-based: extract, measure, design, and test, rather than translate from…
