Artyom Sizov

I'm developing and supporting budgeting, forecasting, and management reporting solutions for a large telecommunications company using SAP BW/4HANA.

I build data flows from SAP S/4HANA through BW/4HANA to BPC for lease accounting, planned depreciation, revenue, and cost reporting. My work includes ABAP routines, DTP full and delta loads, Process Chains, transformations, and event-driven processes.

I develop P&L input forms and analytical reports using CompositeProviders, HANA Calculation Views, F4 value help, ABAP variables, and BEx Queries. I also support the transition to rolling forecasts through SQL analysis, calculation-logic changes, duplicate-data correction, and user support.

I've updated 56 BW mappings, created a consolidated mapping catalogue, and enhanced integration flows between SAP BW and Oracle BI. I also implemented a User-Exit notification mechanism for cost allocation runs that reduced related support requests.
