SAP ECC to Dynamics 365 Data Migration
Choosing Microsoft over S/4HANA? Settle automates the mapping between SAP ECC's deeply normalized structures and Dynamics 365's data entity framework — including organizational structure translation, chart of accounts restructuring, and material master conversion.

Enterprise migrations routinely run months behind schedule. Yours doesn't have to.
This guide is for VPs of IT, data architects, and migration leads at companies moving data from SAP ECC to Microsoft Dynamics 365 — whether you're scoping, planning, or mid-program.
SAP ECC and Microsoft Dynamics 365 use fundamentally different data architectures. Settle bridges this structural gap automatically — handling schema profiling, field mapping, data transformation, and validation that typically consumes months of manual effort.

How Settle automates your SAP ECC to Microsoft Dynamics 365 migration
Settle auto-profiles SAP's organizational hierarchy and proposes the D365 legal entity/site/warehouse mapping — generating a complete org structure crosswalk before data migration begins.
SAP tables are mapped to D365 data entities automatically — including fields that aren't exposed in standard entities, with recommendations for custom entity creation where needed.
Material master views across MARA, MARC, MVKE, and MBEW are consolidated into D365 Released Product entities with product dimensions, inventory parameters, and valuation methods mapped appropriately.
SAP's controlling structures (cost centers, profit centers, internal orders) are translated to D365 financial dimensions with combination validation against D365's account structure rules.

Common challenges migrating from SAP ECC to Microsoft Dynamics 365
SAP organizational hierarchy to D365 legal entity/site model
SAP ECC's organizational structure — company codes, sales organizations, distribution channels, divisions, plants, storage locations — is more granular than D365's legal entity/site/warehouse model. Mapping decisions cascade across all transactional data. A single SAP plant may map to a D365 site, warehouse, or operating unit depending on how it's used.
Explore related migrations →SAP table structures to D365 data entities
SAP ECC uses hundreds of normalized tables accessible via direct SQL or RFC. D365 F&O uses data entities as the primary import interface — each entity aggregates multiple tables with business logic layers. Not all SAP fields surface in standard D365 data entities, and custom entities may need to be created for SAP-specific data patterns.
Explore related migrations →SAP controlling (CO) to D365 financial dimensions
SAP's controlling module — cost centers, profit centers, internal orders, WBS elements — is deeply integrated with the GL. D365 uses financial dimensions as the primary classification mechanism, with project accounting handled separately. Translating SAP CO structures to D365 dimensions requires rethinking how management reporting works.
Explore related migrations →Material master complexity
SAP's material master spans MARA, MARC, MVKE, MBEW, and MARD tables with plant-level, sales org-level, and valuation-level attributes. D365's Released Product entity consolidates much of this but uses product dimensions (configuration, size, color, style) differently. Flattening SAP's multi-view material model while preserving the right detail level is a major mapping challenge.
Explore related migrations →IDOC and custom ABAP interface dependencies
SAP integrations often use IDOCs, BAPIs, and custom ABAP function modules that reference specific table structures. These data dependencies must be identified and mapped to D365 equivalents — typically data entities, OData endpoints, or Power Platform connectors.

The cost of manual SAP ECC to Microsoft Dynamics 365 migration
SAP ECC to Dynamics 365 migrations represent companies choosing Microsoft's ERP over SAP's own S/4HANA upgrade path. This decision is often driven by total cost of ownership — D365's cloud licensing and Azure infrastructure can be significantly cheaper than S/4HANA's licensing plus migration costs. Companies already invested in the Microsoft ecosystem (Office 365, Azure, Teams, Power Platform) see natural synergies. This migration is also common when companies want to avoid SAP's vendor lock-in or find S/4HANA's functional changes too disruptive.
This is one of the most technically demanding ERP migrations because SAP ECC and Dynamics 365 use fundamentally different data architectures. SAP's deeply normalized table structures (KNA1/KNB1/KNVV for customers, MARA/MARC/MVKE for materials) must map to D365's data entities (CustCustomerV3Entity, ReleasedProductV2Entity). SAP's organizational hierarchy (company code, sales organization, plant, storage location) must translate to D365's legal entity and site/warehouse structure. The chart of accounts, controlling structures, and document flows are entirely different between the platforms.
This migration is typically managed by large system integrators (Deloitte, Accenture, Infosys) over 12–24 months. The data conversion workstream alone — profiling custom tables, mapping organizational structures, translating master and transactional data — consumes 30–40% of the total program effort.
Consulting-led delivery for migrations in this class typically runs $1.5M+. Settle prices it fixed and scoped — read the full cost breakdown.
