ECC → S/4HANA Master and transactional data Mapping and load mock-up

Data migration · SAP rollout

Start SAP S/4HANA on the right foot.

4MDG handles data migration to SAP — from legacy systems to SAP and from ECC to S/4HANA — cleansing and standardizing master data at the source before load. We cover master and transactional data, with documented source-to-target mapping, load tests and a controlled cutover, so your new environment is born clean, reliable and ready to operate.

Why ERP projects fail

SAP projects don't slip because of the system. They slip because of the data.

Data quality assessment is one of the most skipped steps before go-live — and the one that costs the most later.

68%

of ERP projects fail or miss their objectives, reaching 73% in discrete manufacturing. Panorama Consulting / Godlan, 2026.

38%

of failure cases have data migration as the cause — the second largest of all. Panorama Consulting, 2026.

189%

of the planned budget is the observed budget-overrun ceiling, with 215% in manufacturing. Panorama Consulting, 2026.

US$ 12,9M

is the average annual cost of poor-quality data per organization. Gartner.

What we migrate

Master data and transactional data — the entire project.

The migration object list below is illustrative: the real scope is defined in Fit-to-Standard workshops, object by object.

Master data

The foundation that supports everything.

Material Fornecedor Cliente Chart of accounts Cost center and profit center Ativos fixos Lista técnica (BOM) Registro info Pricing conditions Material group Plant, storage location and business place Units of measure and conversions Classification and characteristics Supplier: bank and purchasing data Customer: sales and credit data Contacts and addresses Impostos: NCM, CFOP e CST Equipment and functional location Maintenance plan and task list Production routing Purchasing contracts and agreements Info record and source of supply Reference tables and value domains e outros objetos conforme o escopo

Transactional data

What keeps the operation running at go-live.

Accounting balances (general ledger) Títulos a pagar em aberto Títulos a receber em aberto Open purchase orders Open sales orders Stock balances Production orders Maintenance orders Open items in subledgers Batches and serial numbers Estoque em terceiros e em trânsito Reservas e necessidades Open purchase requisitions Remessas e entregas pendentes Service and investment orders Sales and supply contracts Assets: balances and accumulated depreciation Movement history (as scoped) e outros objetos conforme o escopo

The difference

Migrating dirty data is migrating problems. That's why we cleanse before loading.

Before loading, we cleanse the main master data — material, supplier and customer: deduplication, description standardization, enrichment and validation against official sources, using AI and more than 600 public databases. So S/4HANA is born with a golden record, not a replicated legacy.

Data cleansing → Material standardization →

Deduplication and golden record

Similarity matching with scoring, survivor suggestion and attribute-by-attribute survivorship.

Description standardization

Family-based taxonomy, attribute templates and rule-generated descriptions, supported by ADAM.

Tax and registry validation

Business registration number, state registration, certificates, product classification and registry status checked at the official source.

Attribute enrichment

Technical fields, units of measure, packaging, translation and classification completed before load.
