The Dynamics 365 and SAP data integrity gap
What your enterprise data actually looks like when D365 and SAP don't share a single source of truth.
Toggle between the current state and the integrated state. Enterprise integration projects fail because teams underestimate how many data discrepancies exist today. This is what you are actually dealing with.

D365 to SAP integration architecture
Six enterprise data domains. One integration layer. Click any domain to see the architecture.
Each integration domain has its own D365 entities, SAP objects, sync direction, and frequency. Select a domain to see the specific integration scenario for that data type.
Domain 1 - Customer Master
D365 Account records linked bidirectionally to SAP Business Partners
D365 Account creation triggers SAP Business Partner creation via OData API. BP category, role, and company code assigned automatically.
SAP BP updates (payment terms, credit limit) sync back to D365 Account credit fields. Bidirectional conflict resolution by last-modified timestamp.
Existing D365/SAP records matched on VAT number and company name during initial load. Unmatched records flagged for manual review before go-live.

Domain 6 - Reporting and BI
Consolidated data from both D365 and SAP routed to your reporting layer for unified business intelligence
Integration layer exposes a unified API endpoint combining D365 OData and SAP BW or OData queries. Power BI, Tableau, or your chosen BI tool connects to a single endpoint rather than two separate systems.
Entity mapping maintained in the integration layer means reporting queries return data with consistent keys. SAP cost center codes and D365 department codes resolved to shared reporting dimensions.

Integration approach by domain
What each integration domain delivers and how it is built.
D365 is typically the system of record for new customer creation on the CRM side. SAP is the system of record for vendor and supplier data. The integration creates a master data governance layer: new D365 accounts trigger SAP Business Partner creation, SAP vendor changes sync back to D365. Deduplication logic prevents double-creation. Existing records are matched during initial load using configurable matching rules (VAT number, company name, postal code combination).
OData v4 APIDeduplication rulesInitial load matching
The order-to-cash process spans both systems. The integration creates SAP SD documents from confirmed D365 sales orders, receives SAP delivery and billing document references back into D365, and updates D365 order line status as SAP processes goods issue and billing. Cash application from SAP AR can optionally sync back to D365 as order close event. The integration handles partial deliveries, back-orders, and cancellations at line item level.
BAPI/RFC callsLine-level status updatesPartial delivery handling
D365 Supply Chain purchase orders confirmed and sent to SAP MM for goods receipt processing. SAP goods receipt events write back to D365 purchase order as receipt confirmation. SAP vendor invoice parking and posting events sync to D365 as payable liability. Three-way match in SAP uses the D365 purchase order as the reference document. Discrepancies route to the correct team in both systems.
SAP MIGO/MIRO3-way match referenceAP sync
The most sensitive domain. Chart of accounts mapping document approved before build starts. Period-close GL entry replication from D365 to SAP FICO. SAP cost center and profit center hierarchy mapped to D365 financial dimensions. Multi-company and multi-currency setups handled with entity-specific posting rules. Automated reconciliation report generated at each period-close showing matched totals, variances, and unposted items for both systems.

D365 master planning net requirements drive SAP PP production order creation. SAP production confirmation and goods receipt events post completed production to D365 as inventory increase. D365 available-to-promise calculations receive real-time SAP plant stock and production order status. BOM versions and routing from SAP master data used in D365 planning calculations via pre-loaded reference tables.

Pricing approach
Scoped domain by domain. Line-by-line pricing. No commitment to receive a proposal.
Scope factor 1
Domains in scope
Each of the six integration domains (Customer, Orders, Finance, Inventory, Production, Reporting) is scoped and priced independently. Most clients start with Customer Master and Order-to-Cash as Phase 1. Finance and Production typically follow in Phase 2. You choose the scope and sequence.
Scope factor 2
SAP version and API surface
SAP ECC 6.0 uses primarily BAPI/RFC and IDoc interfaces. SAP S/4HANA exposes OData and CDS views in addition to BAPI/RFC. S/4HANA integrations typically have more flexibility but require knowledge of both the new OData layer and legacy BAPI methods for objects not yet migrated to OData.
Scope factor 3
D365 version and customisations
D365 Finance and Operations, D365 Sales (CRM), and D365 Supply Chain Management each have different API surfaces. Custom D365 extensions and ISV solutions that modify standard entities need to be reviewed before scoping. We audit your D365 entity customisations as part of the discovery step.

Challenge
D365 Finance used as front-office ERP and CRM. SAP ECC used for production, warehouse, and procurement. No integration between the two systems. Finance team spending 18+ hours per week manually reconciling customer, order, and GL data. Period close taking 5 days due to manual cross-system reconciliation. Customer credit limits set in SAP not visible in D365 Sales at order time.
Integration approach
Phase 1: Customer Master and Order-to-Cash integration. D365 Account records linked to SAP Business Partners. D365 confirmed orders trigger SAP SD order creation. SAP delivery and billing numbers written back to D365. Phase 2: GL period-close sync and SAP inventory push to D365 on-hand.

Why Redefine for enterprise ERP integration
What makes a Dynamics 365 and SAP integration succeed where others stall.
Field mapping first
Field mapping document approved before any code is written
Every D365 entity mapped to every SAP object, including transformation rules, default values, and conflict resolution logic. Written and approved before build. The document becomes the source of truth for the connector and handover documentation.
BAPI and OData expertise
We use the right API method for each SAP object and D365 entity combination
SAP ECC and S/4HANA expose data through BAPI/RFC, IDoc, and OData. D365 exposes data through OData v4, Data Management Framework, and Business Events. The correct method is chosen per object, not per preference. Some SAP objects only support BAPI; using OData where BAPI is required breaks the integration.
Enterprise error handling
Every failed event classified by SAP return code and D365 response status
SAP BAPI calls return structured error messages with SAP message classes and codes. The integration parses these, classifies the failure type, and routes to the correct resolution path - whether that is an automatic retry, a data correction workflow, or an alert to the IT team with the exact SAP error text.
No middleware vendor
Custom code, no iPaaS platform dependency, no monthly connector subscription
Enterprise iPaaS platforms charge thousands per month for D365-SAP connectors, with additional fees per object type and per message volume. We write a custom connector and deliver the complete source code at go-live. No vendor dependency. No monthly fee. Your internal team or any future partner can maintain it.
Phased delivery
Phase 1 goes live in 3 to 4 weeks, not 6 months
Enterprise integration projects stall because teams try to scope everything simultaneously. We scope and deliver by domain, with each domain producing a working integration in 3 to 5 weeks. You see live data from the highest-priority domain before Phase 2 begins. Risk is isolated per domain, not compounded across the entire project.
Source code on go-live
Complete source code, field map, and runbook delivered on go-live day
Every integration delivers complete source code, the field mapping document used to build the connector, an error handling runbook covering the top error scenarios, and a data flow diagram showing exactly what moves where and when. Your IT team can maintain, extend, or hand over the integration to any future partner.
Common questions
What enterprise teams ask before starting a Dynamics 365 SAP integration project.
Yes. SAP ECC 6.0 integrations use primarily BAPI/RFC remote function calls and IDoc messaging for process-level integration. SAP S/4HANA also supports OData services and CDS view consumption in addition to BAPI/RFC, giving more flexibility per object. We confirm your SAP version, component versions, and any custom Z-function modules or BADI implementations before scoping. Custom SAP extensions that modify standard transaction behavior need to be reviewed because they can change the BAPI call signature or return structure.
D365 custom extensions (X++ code, ISV solutions, data entity customisations) and SAP customer modifications (Z-programs, user exits, BADIs, enhancement spots) are reviewed as part of the discovery step. If a custom field or modified process is in scope for the integration, it must be mapped explicitly in the field mapping document before build. Generic connectors break on customisations because they only handle the standard object schema. We audit both systems and include non-standard fields in the mapping.
Before the integration goes live, existing records in both systems need to be matched and linked. For Customer Master, we run a matching process using VAT number, company name, and postal code as matching keys. Records that match with high confidence are linked automatically. Ambiguous matches are presented in a review report for manual confirmation. Records that exist in only one system are created in the other during initial load. The cut-over sequence is: (1) initial load and matching in a staging environment, (2) client review and confirmation of matched records, (3) production go-live with only new-event sync active.
A single integration domain (for example Customer Master only, or Order-to-Cash only) typically goes live in 3 to 5 weeks from signed scope. A full multi-domain project (Customer Master + Orders + Finance + Inventory) is typically delivered in 10 to 16 weeks, sequenced by domain so you have live integrations running before the full project completes. The finance domain (GL period-close) takes the most time due to chart-of-accounts mapping approval and the requirement to test against your actual period-close cycle. Timeline varies based on D365 version, SAP version, and extent of customisations on both sides.
Fixed-scope, fixed-fee pricing by domain. Each domain is scoped and quoted separately. Discovery (system review, field mapping document, architecture sign-off) is scoped before build begins. No monthly middleware subscription, no per-transaction fees, no connector licence after go-live. Source code and documentation delivered at each domain go-live. You receive a line-by-line proposal before committing to any work beyond discovery.
