Data warehouses that answer real business questions, not just store data. I've designed, built and modernized SAP BI landscapes for Europe's leading enterprises — as an architect who understands your processes as well as your data.
Since 2002 I've been providing professional SAP consulting services to clients across Europe — from Basel and Munich to Vienna, Frankfurt, Helsinki and Budapest. My main area is Business Intelligence: SAP BW and BW/4HANA on HANA, integrated planning, and BusinessObjects.
I've led large projects with both waterfall and Agile methodology, managed budgets in the hundreds of thousands, and built everything from GxP-relevant generic extractors to group-wide planning applications used in over a hundred countries.
My native language is Hungarian, and I work fluently in English and German — including full project delivery in German-speaking environments.
Backend, frontend, planning and project leadership — one consultant, no hand-offs.
Years of experience leading large BI programmes with both waterfall and Agile methodology.

Every assignment since 2002 — scroll to trace the flow.
Evaluating business requirements across the BI landscape and shaping solutions with an integrated architectural approach; aligning and steering several parallel migration programmes — the move to S/4HANA, the upgrade to SAP Business Data Cloud (BDC) and the preparation of the DataSphere migration.
Combining speed with ease of use in building the backbone of a QlikSense-based dashboarding solution covering every aspect of reporting needs — leading the team with an agile approach across several sprints.
Rebuilding an existing integrated-planning-based tool calculating the performance fee charged towards licensors: with HANA views and AMDP code I achieved an 80% performance gain in allocations and vastly increased stability. Improving the ICP tool for intercompany price calculation chains.
Support of the existing BI solution and preparing the move to HANA by modernizing the architecture — streamlining redundant data flows and laying out a clean, low-risk migration path.
Migrating an existing BI implementation to BW/4HANA by rebuilding the entire data flow with LSA++ layered aDSOs and CompositeProviders — leaner models, faster loads and a landscape ready for the next decade.
Creating the necessary automated interfaces to precalculate and transfer data from SAP BI to a native iOS application via an intermediate MSBI layer, displaying critical KPIs on any iOS mobile device.
Achieving retail execution excellence by building a SAP BI-based custom application scoring stores on compliance with sales policies and KPIs such as shelf life and product placement — delivering the right product, in stock, at the right time, at the right price to retail stores across the country.
Created a BI application with QlikView frontend displaying daily sales KPIs — MTD actuals and linear/PY-based calculated MTG with special phasing logic — including variances, in daily use by C-level executives.
Creating a tool used by 100+ countries worldwide for entering and consolidating product margin data in SAP BI and Web Dynpro; plus a master data management tool for maintaining hierarchies and attributes across several systems.
Migrating all consolidated financial reporting from the divisional data warehouses of all Novartis divisions to a single group data warehouse — with all closing-relevant consolidation tasks, division-specific and cross-divisional.
Created Xcelsius dashboards with full financial scope, sourced from SAP BI; data transfer to BO instances with Crystal Reports and LiveOffice; BI-IP-based application for molecule launch planning and tracking.
BI implementation across PP, PS, IM, FI and CO with custom generic extractors and BI–Cognos frontend integration — one extractor template covering five modules, keeping development and maintenance lean.
Function-identical BW upgrade delivered without disruption to ongoing reporting; switched the CO area to the new loading structures and handed over a fully documented system.
Extension of the BI system with FI, CO and EC-PCA — data modeling, process chains and queries delivered end to end, giving finance a single consistent reporting basis.
Operating and material planning with input-ready queries, complex WAD web screens and FOX / user-exit planning functions — replacing offline spreadsheets with one governed planning process.
Assortment (MAP) and sales planning — input-ready queries and complex web screens with WAD (with JavaScript enhancements) and planning functions, integrated with strategic and P&L planning.
Enterprise-wide insurance planning: controlling, balance sheet and P&L, actuary, financial assets, liquidity, HGB–IFRS — with VBA simulation layouts and data flow to BCS.
Connecting the BW system to several source systems via flat-file interface with a dynamic ABAP upload program and check routines; process chain management with upload status logged and displayed in BEx Analyzer; BW monitor entries exported to CSV via FTP; multiple field-level authorizations; workbooks with automatically generated diagrams (VBA).
Central and sector cost-center planning, investments, balance sheet, P&L, cash flow and HGB–French GAAP reconciliation, based on SEM-BPS.
SEM-BPS for cost, income, portfolio, P&L, balance sheet, cash-flow, financial, stock and asset planning — one integrated model covering the full planning cycle of the company.

BW implementation covering general ledger, assets, AP/AR, turnover, budget, FI-SL and HR — the first link in the chain, and the foundation the follow-up planning project was built on.
