At ArcelorMittal Global Business Technologies, I develop and enhance SAP BW/4HANA and SAP HANA reporting solutions, including Calculation Views, Composite Providers, queries, and data models. I support delivery from requirements analysis through development, testing, deployment, and production support.
On the AUDI NAKA migration project, I participated in migrating SAP BW 7.5 to BW/4HANA, converting Info Cubes, DSOs, and Multi Providers to Advanced DSOs and Composite Providers. I also worked on BEx query conversion, testing, performance tuning, and documentation for the migration.
