We implement SAP ECC and S/4HANA, migrate your data from ECC to S/4HANA using Syniti ADM, and build governance frameworks that keep your data trusted — long after go-live.
Vilahy Data Solutions is a focused SAP consulting firm built on one principle: senior specialists do the work directly. No layers. No hand-offs. Every engagement is led by consultants with deep, hands-on experience across the full SAP data landscape.
We cover the complete spectrum — from implementing SAP ECC and S/4HANA from the ground up, to migrating decades of ECC data into S/4HANA using Syniti ADM, to building governance frameworks that protect data quality long after your project closes.
Our team understands both sides of SAP data: the functional configuration that shapes how data behaves in business processes, and the technical extraction, transformation, and loading that moves data reliably between systems. This dual depth means we catch problems before they become post-go-live incidents.
With SAP ending mainstream support for ECC in December 2027, the window for a structured, risk-managed migration is narrowing. We help enterprises plan early, migrate cleanly, and govern continuously.
Each engagement is shaped to your program, timeline, and industry. Senior delivery from day one.
We deliver end-to-end SAP ECC and S/4HANA implementations — from business process blueprinting and system configuration through testing, cutover, and go-live stabilisation. Whether you are implementing SAP for the first time or transforming from ECC to S/4HANA, we bring the functional and technical depth to do it right.
We support all three S/4HANA deployment paths: Greenfield (new clean-slate build), Brownfield (system conversion retaining ECC configuration), and Hybrid (selective data migration combining both).
Discuss your project →Data migration is the highest-risk workstream in any S/4HANA program. Structural differences between ECC and S/4HANA mean data cannot simply be moved — it must be extracted, profiled, cleansed, transformed, and validated against S/4HANA's simplified data model before it is loaded.
We use Syniti Advanced Data Migration (ADM) — the SAP-endorsed migration platform — to manage the full migration lifecycle with complete visibility, rule-driven transformation, and wave-by-wave reconciliation across SIT, UAT, Mock, and Go-Live loads.
Plan your migration →Clean data migrated at go-live degrades rapidly without a governance framework. Duplicate records, inconsistent naming conventions, unapproved changes, and missing mandatory fields erode data quality within weeks — unless ownership, workflows, and validation rules are embedded from the start.
We design and implement governance frameworks built on SAP Master Data Governance (MDG) — establishing a single source of truth for materials, vendors, customers, and financial data — with workflows, stewardship roles, and quality monitoring that sustain integrity over time.
Build your framework →SAP Readiness Check, data landscape audit, migration object inventory, governance maturity scoring, and project scoping.
Migration rules, field mappings, transformation logic, governance workflows, and cutover strategy — all documented and baselined.
SAP configuration, Syniti ADM setup, MDG domain configuration, LTMC staging table prep, and data cleansing execution.
SIT, UAT, and Mock load cycles. SQL reconciliation against source and target. Error resolution. Business sign-off on data quality.
Cutover execution, delta loads, hypercare support, and governance framework handover so data quality compounds after go-live.
Most organisations only understand how poor their ECC data quality is once migration has already started. We run structured data profiling early — before design is locked — so quality issues are remediated during the project, not after go-live.
S/4HANA removes or consolidates hundreds of ECC tables. Data valid in ECC — BSEG/BKPF splits, BSID/BSAD separation — must be restructured. Without deep functional and technical knowledge, these transformations are missed until UAT.
IT delivers the migration platform; business teams assume someone else is cleaning the data. Without defined data owners, stewards, and sign-off responsibilities mapped to real people, validation stalls and cutover is delayed.
Data quality achieved during migration erodes within months without a governance framework. Duplicate materials are created, vendor records diverge, and the single source of truth disappears. We build governance that lasts well beyond the project.
Syniti Advanced Data Migration (ADM) is the SAP-endorsed migration platform used by the world's largest enterprises. It provides end-to-end visibility into every data object, every rule, and every load wave — replacing spreadsheet-based tracking with a structured, repeatable platform.
For Vilahy, Syniti ADM means our clients always know exactly where their data stands — how many records are migration-ready, how many are blocked by quality issues, and what actions are needed before the next load wave. Nothing is hidden.
Most SAP partners split functional consultants from technical data engineers. Our team works across both dimensions — understanding business processes and writing the SQL, migration rules, and reconciliation queries that make data correct in the target system.
We are not a broad SI that adds Syniti as a line item. We understand the platform deeply — Advanced View Builder configuration, Gen SQL log error diagnosis, load cycle governance gates, and staging table reconciliation down to the field level.
The people who scoped your project are the people delivering it. No hand-offs to junior analysts after the kick-off. Our senior specialists are hands-on throughout discovery, build, testing, and go-live — not just in governance meetings.
We never treat governance as an add-on. Every migration engagement includes a governance readiness assessment and a handover operating model so the data quality we help you achieve continues to compound after our engagement closes.
SAP data requirements vary significantly by industry. Our experience spans sectors where SAP data complexity is highest — and the cost of getting it wrong is greatest.
End-to-end SAP implementation or ECC-to-S/4HANA migration — from assessment through go-live and hypercare. Senior delivery, fixed scope, clear milestones from day one.
Embedded data migration or governance lead within your existing SI-led program. We own the data workstream so your SI can focus on configuration and integration.
A time-boxed, structured evaluation of your ECC data landscape — profiling quality, identifying migration risk, and producing a clear go/no-go recommendation with a remediation roadmap.
Ongoing strategic advisory for organisations building or maturing their SAP master data governance capability — including MDG design, stewardship model setup, and quality KPI frameworks.
Whether you are planning your migration, already mid-project, or looking to establish governance that lasts — we bring the depth and directness to make it work. Tell us where you are, and we will tell you exactly how we can help.
