Adaptors / Dynamics 365 Business Central
Dynamics 365 Business Central adaptor
Reusable delivery templates, orchestration patterns, and deterministic validators.
The Dynamics 365 Business Central adaptor targets new implementations and migrations to Business Central across core modules including Finance, Inventory & Product, Sales & Customer, and Procurement. It includes mapping templates, load orchestration, and deterministic validators that produce audit-ready evidence at every rehearsal.
What it accelerates
- Prototype speed: pre-built extraction and mapping templates for core Business Central entities reduce time-to-first-prototype significantly
- Repeatable rehearsals: orchestration patterns and run sequencing produce identical results on every run
- Audit-ready evidence: reconciliation packs with counts, totals, deltas, and balancing produced automatically
- Reduced manual effort: deterministic code-printing replaces hand-coded migration scripts
- Knowledge retention: delivery logic sits in the adaptor, not in individuals, reducing key-person dependency
How it works with elfware
The controlled non-determinism model applied to Dynamics 365 Business Central:
- 1Human decisions: consultants define scope, modules, business rules, and exception handling for the migration
- 2AI-assisted optioning: surfaces mapping choices and highlights gaps in data coverage across finance, inventory, sales, and procurement
- 3Governed specs: locked decisions become the input to deterministic generation. No ambiguity, no drift
- 4Deterministic generation: code-printing produces extraction scripts, transformation logic, load files, and orchestration from the governed spec
- 5Deterministic validators: every row, every field, every cross-reference checked against governed rules before cutover
- 6Rehearsal and cutover: proven rehearsal chain executed identically each run until go-live
AI boundary: AI never processes customer data; it supports mapping and delivery configuration only. When AI assists with code generation, the output is reviewed, QA'd, and verified in test runs before deployment to any system.
Source vs target usage
As a target (Business Central)
Loading data into Dynamics 365 Business Central for new implementations, upgrades, or migration projects.
- Master data loading: customers, vendors, items, G/L accounts via APIs or configuration packages
- Opening balances: G/L balances, customer/vendor balances, inventory quantities and values
- Configuration data: posting groups, dimensions, number series, organisational setup
- Transactional seeding: open orders, open invoices, open purchase orders at cutover
- Reconciliation: post-load validators confirm data integrity across all loaded domains
As a source (Business Central)
Extracting data from Dynamics 365 Business Central for migration to other systems.
- Full extraction: complete master data and configuration export via APIs
- Delta extraction: changed records identification for incremental loads
- Historical data: transaction history with audit trail preservation
- Reconciliation: source counts and totals for migration validation
Typical artefacts delivered
Mapping templates
Pre-built source-to-target mapping documents covering Business Central entities with transformation rules, defaults, and exception handling.
Orchestration / run groups
Sequenced run plans ensuring dependencies are respected (e.g., posting groups before customers, items before inventory).
Deterministic validators
Automated checks for referential integrity, data completeness, cross-entity consistency, and business rule compliance.
Reconciliation / evidence pack
Counts, totals, deltas, and balancing reports that provide audit-ready sign-off evidence for each rehearsal and cutover.
Cutover rehearsal playbook
Step-by-step runbook for rehearsal execution including timing, checkpoints, rollback criteria, and go/no-go gates.
Interfaces and data domains
| Domain | Typical entities | Cadence | Notes |
|---|---|---|---|
| Cross-Domain | Payment terms, shipment methods, units of measure | Full | Foundation reference data |
| Finance | G/L accounts, posting groups, journal lines, dimensions | Full + delta | Posting group dependencies |
| Inventory & Product | Items, item categories, inventory posting, locations | Full + delta | Item tracking considerations |
| Procurement | Vendors, purchase orders, vendor posting groups | Full + delta | Vendor bank details |
| Sales & Customer | Customers, sales orders, customer posting groups, pricing | Full + delta | Customer credit limits |
Common risks and how we mitigate them
Posting group complexity
Adaptor handles all posting group types (general, customer, vendor, inventory, etc.) with validators that check referential integrity.
Dimension value dependencies
Mapping templates handle dimension codes and values with transformation logic for legacy dimension migration.
Number series conflicts
Number series analysis ensures no conflicts with existing data and adequate capacity for migration and post-go-live.
Currency and exchange rate handling
Transformation templates handle multi-currency scenarios with exchange rate mapping and historical rate preservation.
Item tracking and serial numbers
Adaptor supports item tracking codes, serial numbers, and lot numbers with validation for uniqueness and format compliance.
Cutover window constraints
Rehearsal playbook provides accurate timing data from previous runs, enabling confident go/no-go decisions.
