Overview
Moving from reybex to Microsoft Dynamics 365 is a full-ERP migration that requires careful sequencing around reybex's non-public API and Germany's GoBD compliance requirements. reybex does not publish its API schema; we perform a schema-discovery step during pre-migration audit to enumerate field names, data types, and object relationships before writing any mapping. GoBD-compliant financial records carry TSE signatures, document numbers, and tax code assignments that are legally required in Germany; we map these explicitly and flag any records with missing TSE data for manual review before cutover. EDI transaction sets (ORDERS, INVOIC, DESADV) are platform-native and cannot transfer to a non-EDI destination; we export EDI partner mappings and configuration metadata as a reference document. Workflows, automations, and B2B trade rules built inside reybex do not migrate; we deliver a written inventory of these for the customer's implementation partner to rebuild in Dynamics 365. Business Central ($70-110 per user per month) is the natural destination for SME-scale reybex customers; Finance and Supply Chain Management ($180 per user per month) are options for companies that require enterprise-scale manufacturing or multi-entity financial consolidation.

Object mapping
Each row shows how a reybex object lands in Microsoft Dynamics 365 Business Central, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
reybex
Customers
Microsoft Dynamics 365 Business Central
Customer
1:1reybex Customers map to Dynamics 365 Customer records, which can serve as a Person or Company customer type. Address records (street, city, postal code, country) map to the Dynamics 365 Address table; German address formats (Straße, Hausnummer split) are preserved as separate address lines or parsed into structured fields during transform. reybex customer-specific pricing tiers map to Customer Price Groups in Dynamics 365. Tax identification numbers map to VAT Registration Number on the Customer card.
reybex
Articles
Microsoft Dynamics 365 Business Central
Item
1:manyreybex Articles (SKUs with variant matrices for size, color, etc.) unpack into Dynamics 365 Item records. The parent Article becomes the Item; each variant (size-color combination) becomes a separate Item Variant attached to the parent. Multi-language article descriptions (German, English) map to Dynamics 365 Item Translation records. reybex's article-specific units of measure (Stück, kg, Liter) map to Dynamics 365 Unit of Measure groups. Article pricing from reybex price lists maps to Sales Prices on the Item or to Customer Price Groups for customer-specific pricing.
reybex
Sales Orders
Microsoft Dynamics 365 Business Central
Sales Order
1:1reybex Sales Orders map to Microsoft Dynamics 365 Sales Order. The order header (customer reference, order date, delivery date, shipping method) maps to corresponding Sales Order header fields. Line items resolve the Item number from the Article mapping and preserve quantity, unit price, discount percent, and line amount. reybex order status (opened, confirmed, partially shipped, completed, cancelled) maps to Dynamics 365 Status and Shipment Status fields. Open orders migrate first; archived or completed orders migrate based on the customer's data retention scope defined during scoping.
reybex
Purchase Orders
Microsoft Dynamics 365 Business Central
Purchase Order
1:1reybex Purchase Orders map to Dynamics 365 Purchase Order. The vendor reference maps to the Dynamics 365 Vendor account resolved from the vendor mapping. PO approval workflows from reybex (configured in the Run tier) do not transfer; we flag the workflow structure in the automation inventory document for the customer's admin to reconfigure in Dynamics 365 using Approval Workflows or Power Automate. Line items map by resolving the Item number from the Article mapping against the vendor's item cross-reference if configured.
reybex
Inventory / Stock Levels
Microsoft Dynamics 365 Business Central
Item Ledger Entry + Warehouse Entry
lossyreybex real-time stock quantities map to Dynamics 365 Item Ledger Entries for quantity tracking and Warehouse Entries for bin-level placement. Each reybex warehouse location maps to a Dynamics 365 Location code. Lot and batch tracking data from reybex maps to Dynamics 365 Item Tracking Codes and Item Tracking Lines if the customer uses serialized or lot-tracked inventory. We schedule inventory exports during low-activity windows and cross-reference open order quantities to produce a consistent cutover balance that excludes in-flight allocations.
reybex
Invoices
Microsoft Dynamics 365 Business Central
Sales Invoice
1:1reybex Invoices map to Microsoft Dynamics 365 Sales Invoice records with GoBD-compliant metadata explicitly preserved. TSE signatures, document numbers, and tax codes (German tax codes MwSt 19%, 7%, 0%, and intra-Community supply codes) map to the corresponding Dynamics 365 fields on the posted invoice. We flag any reybex invoice records missing TSE data for manual review before the cutover. Multi-currency invoices from EU cross-border trade map to Dynamics 365 Currency and exchange rate fields with the original currency amount preserved alongside the euro equivalent.
reybex
Banking / Cash Transactions
Microsoft Dynamics 365 Business Central
Bank Account Ledger Entry / Cash Document
1:1reybex bank statements and POS cash register transactions (TSE-signed receipts) map to Dynamics 365 Bank Account Ledger Entries or Cash Document records depending on the selected Finance module configuration. TSE-signed receipt metadata maps to external document number or a custom field capturing the TSE signature hash for audit trail continuity. German cash register (Kasse) configurations map to Dynamics 365 Cash Desk functionality in Business Central if the German localization is enabled.
reybex
Projects
Microsoft Dynamics 365 Business Central
Job
1:1reybex Project records map to Dynamics 365 Job (Business Central) or Project Operations entities. Task hierarchies and milestones from reybex flatten to Job Task Lines and Job Planning Lines in Business Central. Time entries map to Job Journal Lines for hours; expense items map to Job Journal Lines for item consumption. Budget amounts from reybex are stored as reference values in Job Budget fields for the customer's admin to verify post-migration. Project status (active, on-hold, completed) maps to the Job status field.
reybex
Manufacturing / Production Orders
Microsoft Dynamics 365 Business Central
Production Order
1:1reybex BOMs (bills of materials) and production routings map to Dynamics 365 Production Bill of Materials and Production Routing. Finished goods outputs map to Production Order header and line items with the quantity and due date preserved. Material consumption lines map to Production Order Component Lines resolved against the Item mapping. Machine capacity planning data (work center calendars, setup and run times) maps to Dynamics 365 Capacity Ledger Entries if the customer uses capacity scheduling; this requires a partner-configured work center and machine center setup in the destination.
reybex
CRM Activities / Engagements
Microsoft Dynamics 365 Business Central
Activity (Task, Phone Call, Appointment)
1:1reybex CRM activities (calls, emails, meetings, tasks, notes) tied to customer records map to Dynamics 365 Activity records. reybex call dispositions and duration map to the Dynamics 365 Phone Call subject with custom fields for disposition and duration. reybex meeting entries with attendee lists map to Dynamics 365 Appointment records with the attendee list preserved in the Required Attendees and Optional Attendees fields. reybex task engagements map to Dynamics 365 Task records with Status, Priority, and ActivityDate preserved.
reybex
Custom Fields
Microsoft Dynamics 365 Business Central
Custom Fields / Extensions
lossyreybex custom fields on Articles, Customers, and Sales Orders require schema discovery per tenant before mapping. We detect all custom field definitions during the pre-migration audit visit using reybex's frontend endpoint introspection method. Each discovered custom field is assigned a Dynamics 365 field type (Text, Decimal, Integer, Boolean, Option) and mapped to the corresponding table extension in Business Central or Finance. Custom field data migrates as part of the parent object import phase.
reybex
EDI Documents
Microsoft Dynamics 365 Business Central
EDI Configuration (reference only)
lossyreybex EDI transaction sets (ORDERS, INVOIC, DESADV) are platform-native message formats that do not transfer to Dynamics 365 as functional records. We export EDI partner mappings (partner ID, IDOC type, message format) as a structured reference document that the customer's implementation partner or EDI middleware provider (LANSA, Extrom, or SEEBURGER) uses to reconfigure EDI in Dynamics 365. Actual EDI transaction history remains in reybex for audit reference but is not imported into Dynamics 365.

Pair-specific challenges
Migration approach
Schema discovery and API access
We request reybex API credentials and conduct a schema-discovery visit using reybex's frontend endpoint introspection method to enumerate field names, data types, object relationships, and custom field definitions for the specific tenant. This discovery output feeds the mapping matrix and confirms which reybex modules (Go, Run, Fly) are active so we scope the correct object set. We simultaneously assess the target Dynamics 365 edition (Business Central Essentials, Premium, or Finance) with the customer's implementation partner and confirm Azure region and localization requirements for GoBD compliance.
Data audit and GoBD compliance review
We profile reybex data across all objects in scope for data quality issues: duplicate customers, inconsistent address formats, missing TSE signatures on financial records, inactive items still referenced in open orders, and variant matrices that need unpacking. We produce a data quality report and a remediation workstream for the customer's data steward to address before migration. GoBD compliance is reviewed specifically: every financial record (invoices, cash transactions, journal entries) must carry a TSE signature, document number, and valid tax code or be flagged for manual correction.
Destination schema configuration
We work with the customer's Dynamics 365 implementation partner to configure the destination environment: Business Central or Finance locations, units of measure, tax codes (matching German MwSt rates), customer and vendor posting groups, item posting groups, and chart of accounts mapping. For reybex EDI configurations, we document partner mappings and message format requirements for the EDI middleware reconfiguration that the partner handles separately. We deploy any required Dynamics 365 extensions for German localization and verify TSE field mappings are writable in the target environment.
Sandbox migration and reconciliation
We run a full migration into a Dynamics 365 Sandbox using production-like data volumes. The customer's implementation partner and finance team reconcile record counts (Customers in, Items in, Sales Orders in, Purchase Orders in, Posted Invoices in, Inventory balances in, Activities in), spot-check fifty random records against the reybex source, and validate GoBD metadata on a sample of posted invoices. Any mapping corrections or data quality issues surface here and are resolved before production migration begins. EDI partner configuration is reviewed against the reference document to confirm completeness.
Production migration in dependency order
We run production migration in record-dependency order: Locations and Units of Measure first (referenced by all inventory and item records), then Items and Item Variants (referenced by order lines), then Customers and Vendors, then Inventory (Item Ledger Entries with resolved Location), then Sales Orders and Purchase Orders, then Posted Invoices and Cash Documents (GoBD metadata verified per record), then Activities (Tasks, Phone Calls, Appointments via API batch), then Projects and Production Orders. Each phase emits a row-count reconciliation report before the next phase begins. EDI transaction history remains in reybex and is not imported.
Cutover, validation, and automation rebuild handoff
We freeze reybex writes during cutover, run a final delta migration of any records modified during the migration window, then enable Dynamics 365 as the system of record. We deliver the Workflow and EDI Configuration Inventory document to the customer's implementation partner. We support a two-week hypercare window where we resolve any record-level reconciliation issues raised by the customer's team. We do not rebuild reybex workflows or EDI rules as Dynamics 365 workflows or EDI configurations inside the migration scope; those are separate engagements with the customer's implementation partner.
