Enterprise ERP Blueprint & Technical Reference Manual

System Architecture & Core Ledger Principles

This cloud-ready Enterprise Resource Planning (ERP) platform is built on a high-throughput PHP engine and relational database architecture. Designed to mirror the operational mechanics of Microsoft Dynamics 365 Business Central, it enforces strict ledger immutability: once posted, journals and documents are sealed permanently in primary ledger tables. Adjustments are executed exclusively through explicit Storno reversal entries, preserving full audit integrity across financial and operational cycles.

⚙️ Three-Tier Cloud Architecture Specification

1. Presentation Layer (TypeScript / Tailwind Web Client)

Renders role-tailored workspaces, FastTabs, dynamic grid controls, and real-time status notifications over REST/OData endpoints.

2. Middleware Logic Engine (PHP 8.x Core Server)

Executes business logic routines (`Codeunit 11 Gen. Jnl.-Check Line`, `Codeunit 12 Gen. Jnl.-Post Line`, Cost Adjustment routines, SIFT aggregations, and event triggers).

3. Relational Database & Ledger Storage Layer

Persists normalized table schemas, executes SumIndexField Technology (SIFT) aggregate views, and enforces atomic ACID transaction locks during document posting.

Financial Management & Multi-Dimensional Analytics Engine

The Financial Engine anchors all operations around a tree-structured Chart of Accounts (`Table 15 G/L Account`), double-entry transaction validation (`Table 17 G/L Entry`), and matrix-driven account mapping (`Table 252 General Posting Setup`). Rather than bloating physical transaction tables with separate columns for each dynamic tag, the system uses a normalized Dimension Set Engine (`Table 480`) to combine arbitrary dimensions into single integer surrogate keys (`Dimension Set ID`).

Tree view showing Posting vs. Heading/Total types and dynamic FlowFields.

Live SIFT FlowFields

No.	Account Name	Income/Balance	Account Type	Net Change (FlowField)	Balance (FlowField)

SIFT / FlowField Calculation Engine Simulator

FlowFields do not store physical balances. They compute aggregations dynamically on-the-fly using indexed SQL formulas and optional virtual FlowFilters (e.g. `Date Filter`, `Global Dimension 1 Filter`).

Target Account (`No.`)

Date FlowFilter (`Posting Date`)

Global Dim 1 Filter (`DEPT`)

Dimension Set Engine (`Table 480`)

Combines dynamic dimension key-value tags into a normalized tree. All document lines hold a single integer `Dimension Set ID`.

Dimension Combination Matrix

DEPARTMENT (Dim Code)

PROJECT (Dim Code)

REGION (Dim Code)

General Posting Matrix (`Table 252`)

Maps `Gen. Bus. Posting Group` × `Gen. Prod. Posting Group` to COGS, Sales, and Clearing Accounts.

NATIONAL × RAW MAT COGS: 60100 | Sales: 40100

EXPORT × RETAIL COGS: 60200 | Sales: 40200

EU × SERVICE COGS: 60300 | Sales: 40300

Security Administration, RBAC & Developer Extensibility

System access is governed by granular Role-Based Access Control (RBAC) via Permission Sets (`Table 2000000005 Permission`), defining explicit Read, Insert, Modify, Delete, and Execute (`RIMDX`) privileges down to individual table objects and row-level security filters. Changes are audited via the Change Log Engine (`Table 405`).

Security Access Control Schema (`Table 2000000005`)

Role ID	Object Type	Object Name / ID	Read	Insert	Modify	Delete	Exec

Change Log Engine (`Table 405`)

Field-level audit trail storing Old Value vs New Value with user timestamps.

Table 18 Customer (Credit Limit LCY)

Old: $50,000 ➔ New: $100,000
