Overview
Moving from SAP S/4HANA Cloud to Odoo ERP is a structural migration from a normalized, enterprise-grade data model to a relational open-source framework. SAP's unified Business Partner object (covering both customers and vendors) splits into Odoo's separate Partner record with Contact records attached. The SAP Chart of Accounts and Company Code hierarchy maps to Odoo's Account Type and Property configuration. We extract data through the SAP OData API using migration objects scoped to the Migration Cockpit structure, transform the records against Odoo's required field types, and load via CSV with Odoo's native import tools. Journal entries and historical financial data require careful volume planning because Odoo's accounting ledger processes every line individually. Workflows, automations, BTP extensions, and RISE contract services do not migrate; we deliver a written inventory of these for the customer's admin to rebuild in Odoo or document as decommissioned.

Object mapping
Each row shows how a SAP S/4HANA Cloud object lands in Odoo ERP, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
SAP S/4HANA Cloud
Business Partner (Customer)
Odoo ERP
Partner (type: Customer)
1:1SAP Business Partners with role Customer (KNA1) map to Odoo Partner records with partner_type = 'contact' and a parent company if B2B. The SAP BP number becomes Odoo's ref field for cross-reference. Address data (ADDR1-4, city, country, postal code) migrates to Odoo's address fields. Payment terms from SAP (LFB1-ZAHLS) map to Odoo Partner Properties. We resolve the country code ISO mapping from SAP's land1 to Odoo's res.country records during the transform phase.
SAP S/4HANA Cloud
Business Partner (Vendor)
Odoo ERP
Partner (type: Vendor)
1:1SAP Business Partners with role Vendor (LFA1) map to Odoo Partner records with partner_type = 'vendor'. The SAP vendor number becomes Odoo's ref field. Purchasing data from LFA1 (such as vendor account group and order currency) migrates to Odoo Partner properties. We split vendors and customers at migration time using the SAP BP role assignment rather than creating a single BP that serves both roles.
SAP S/4HANA Cloud
Material / Product
Odoo ERP
Product Template + Product Variant
1:1SAP Materials (MARA) map to Odoo Product Template records with the SAP material number stored in Odoo's default_code and barcode fields. SAP material type (MTART) determines Odoo product type: ROH/HALB/FERT map to storable product with BoM where applicable; HAWA maps to consumable; DIEN maps to service. Unit of measure conversions from MARA-MEINS map to Odoo's uom_id and uom_po_id with the SAP T006 unit table as the conversion reference. Plant-specific data (MARD, MARC) migrates to Odoo stock routes and warehouse-specific route assignments.
SAP S/4HANA Cloud
Chart of Accounts
Odoo ERP
Account (Chart of Accounts)
1:1SAP GL Accounts (SKA1) map to Odoo account.account records with the SAP account number stored in Odoo's code field. The SAP account type (KTOPL) determines Odoo account type: KTOKP values map to Odoo's account.account.type selection (payable, receivable, liquidity, other). Company code assignments (SKB1) map to Odoo account.account.allowed_company_ids for multi-company chart of accounts isolation. Country-specific chart of accounts templates (India, US, Germany) migrate from SAP's country-specific fiscal localization to Odoo's fiscal localization module.
SAP S/4HANA Cloud
Journal Entry (Financial Document)
Odoo ERP
Account Move (Journal Entry)
1:manySAP Journal Entries (BKPF/BSEG) map to Odoo account.move records with one move per SAP document number + fiscal year. SAP document type (blart) maps to Odoo's journal_id selection: ABAP document type RFBEGB (payment) maps to bank journal, RGRREB (recurring) maps to miscellaneous journal, ABAP type RE (invoice) maps to purchase or sale journal. Each BSEG line item becomes an account.move.line record with account_id from the SAP HKONT field. Tax codes (MWST) map to Odoo tax_ids resolved through the SAP tax code to Odoo tax mapping table created during schema design. Historical journal migrations require volume planning because Odoo processes every line individually; we chunk loads by fiscal period to avoid timeouts.
SAP S/4HANA Cloud
Open AP / AR
Odoo ERP
Account Move (Open Invoice) + Partner Open Amount
1:1SAP open payables and receivables (BSEG with clearing date blank) migrate to Odoo account.move records in draft state for customer reconciliation before posting. The SAP document number and fiscal year become Odoo's ref for cross-reference. Remaining open amount (WRBTR - DMBTR) maps to Odoo's amount_residual. Partially cleared items (DMBTR not equal WRBTR) require a split: the cleared portion becomes a posted move, and the residual becomes a new draft invoice in Odoo. The clearing document (VBRK/RVE) is not migrated; only the open residual is carried forward.
SAP S/4HANA Cloud
Sales Order
Odoo ERP
Sale Order
1:1SAP Sales Documents (VBAK/VBAP) map to Odoo sale.order and sale.order.line records. SAP Sales Area (VKORG/VTWEG/SPART) maps to Odoo's warehouse_id and picking_policy configuration. Pricing conditions from KONV migrate to Odoo order lines with the SAP price list mapped to Odoo's pricelist_id. Schedule lines (VBEP) with confirmed delivery dates migrate to Odoo's commitment_date. The SAP document flow (VBFA) is not migrated as linked records but documented separately for the customer's admin to re-establish in Odoo's delivery and procurement linked-document view.
SAP S/4HANA Cloud
Purchase Order
Odoo ERP
Purchase Order
1:1SAP Purchase Orders (EKKO/EKPO) map to Odoo purchase.order and purchase.order.line records. Purchasing organization (EKPO-werks) maps to Odoo's warehouse_id and property_stock_location on the vendor Partner. Delivery address from EKKN (purchase order account assignment) migrates to Odoo's picking destination address. Inco terms and payment terms from the vendor master (LFB1) migrate to Odoo purchase order fields. Purchase order confirmations and scheduling agreements (MEkk/Mekpo) map to Odoo's blanket orders where applicable.
SAP S/4HANA Cloud
Project (PS Module)
Odoo ERP
Project
1:1SAP Project System WBS elements (PRPS) and networks (AFKO/AFPO) map to Odoo project.task records with hierarchical structure preserved. SAP project billing plan assignments (VFKP) map to Odoo's project Milestones with due dates and invoicing percentages. Cost planning data from the PS module migrates to Odoo project's analytic account budget tracking. Deeply nested WBS hierarchies require flattening or level-based import sequencing to satisfy Odoo's two-level project-task constraint.
SAP S/4HANA Cloud
User / Business Role
Odoo ERP
User
1:1SAP S/4HANA user accounts (USR01/AGR_USERS) map to Odoo res.users records. SAP business role assignments map to Odoo's security groups: SAP role PFCG_TEST becomes Odoo group_sale_user, group_account_invoice_user, or project_user depending on the role's authorization object scope. We extract user email addresses from SAP's ADRP table as the Odoo login. SAP organizational unit assignments (HR data) map to Odoo's employee records if the HR module is in scope.
SAP S/4HANA Cloud
Custom Fields (EEWC)
Odoo ERP
Custom Fields (res.partner, product.template)
lossySAP S/4HANA Cloud Public Edition custom fields created via Enable Extended Workspace Configuration (EEWC) map to Odoo custom fields on the equivalent model. We pre-create the destination fields in Odoo before migration using ir.model.fields with the appropriate type (char, float, selection, many2one). The SAP field name becomes the Odoo field name with underscores replacing SAP's naming convention. EEWC fields tied to SAP-specific logic (such as data sources or calculated fields) cannot migrate and are flagged for functional review.
SAP S/4HANA Cloud
Product Bill of Materials
Odoo ERP
mrp.bom
1:1SAP Bills of Material (STKO/STPO) map to Odoo mrp.bom records. SAP BOM components (STPO-KDSTB) map to Odoo mrp.bom.line records with the component product resolved via SAP material number. BOM quantities and unit of measure from SAP's MARC (base quantity) migrate to Odoo's product_qty with the SAP unit mapped via T006. Routing operations from SAP routing work centers (CRHD) map to Odoo mrp.routing/workcenter records if manufacturing is in scope.

Pair-specific challenges
Migration approach
Discovery and OData extract scoping
We audit the SAP S/4HANA Cloud tenant across Public/Private/RISE deployment variant, active modules (Finance, MM, SD, PS), Business Partner role distribution (customer vs vendor ratio), material count and variant complexity, journal entry volume by fiscal year, and open PO/SO count. We confirm the OData API availability for each migration object and document the SAP country-specific localization requirements for the destination Odoo fiscal country pack. The discovery output is a written migration scope with record counts per object, a journal entry cut-off recommendation, and the Odoo edition (Community self-hosted or Enterprise SaaS) decision.
Schema design and split rule definition
We design the Odoo destination schema: res.partner records (with is_company, customer_rank, supplier_rank), product.template and product.product, account.account chart of accounts, account.journal configuration for each SAP document type, and project.project structure for the PS module. The Business Partner split rule (SAP BP to Odoo Partner + Contacts) is defined here with the role table reference. The Chart of Accounts three-tier to single-tier resolution is documented with the Company Code assignment. Schema is validated in an Odoo staging environment before any production data moves.
Data extraction via SAP OData API
We extract data from SAP S/4HANA Cloud using the OData API with migration objects scoped to the SAP Migration Cockpit structure where available. We run paginated reads using $skiptoken with endpoint-specific concurrency limits (max 15 parallel for journal entries, 5 for business partners, 10 for materials). Checkpoints are written every 10,000 records for resume capability. We extract Business Partners first (with role and address), then Chart of Accounts, then Materials, then open AP/AR, then historical journal entries by fiscal period, then POs/SOs last. Each extract produces a manifest file with record counts and a SHA-256 hash for reconciliation.
Transform and load into Odoo staging
We run the transform layer: SAP BP number to Odoo Partner ref, SAP material number to Odoo product.default_code, SAP GL account to Odoo account.account.code, SAP tax code to Odoo account.tax. The SAP Business Partner split is applied at this stage, producing a Partner CSV and a Contact CSV for each BP with multiple roles. Journal entries are transformed to account.move CSV with line-level decomposition. We load into an Odoo staging database (Full Copy or a fresh Odoo instance) using Odoo's CSV import framework with field mapping validated before each batch. Reconciliation reports compare Odoo record counts against the SAP extract manifest.
Sandbox validation and customer sign-off
The customer's finance and operations leads spot-check 25-50 records per object against the SAP source: verify BP address completeness, GL account assignments, journal entry totals, open AP/AR balances, and PO/SO line pricing. Any mapping corrections are documented and applied in the transform layer before the production migration run. The SAP write freeze window is agreed upon for the production cutover date. The Odoo staging database is retained as a rollback reference until the production go-live is validated.
Production migration and cutover
We run the production migration in dependency order: Account (chart of accounts), Partner + Contact, Product + BoM, then financial records (open AP/AR as draft invoices, journal entries by period, then POs/SOs). Each phase emits a reconciliation report before the next phase begins. The SAP tenant is placed in read-only mode during cutover. A final delta migration captures any records modified during the cutover window. We validate Odoo's trial balance and open AP/AR aging against the SAP source before declaring go-live. We deliver a written automation inventory (SAP workflows, approval chains, and PS project assignments) for the customer's admin to rebuild in Odoo Studio or via Python modules.
