sap – Visualisation of business processes in corporate accounting, controlling , consolidation, insurance industry

Can somebody recommend me a tool to visualize business processes in accounting, controlling, consolidation, group reporting of insurance industry.

Example : data flows from multiple source systems into SAP FICO, data is aggregated and flows into SAP BW4Hana via complex transformations , later on this data flows into another consolidation system with an extra set of transformation…..
Each steps involves teams, reference data, transformation logic, manual process..
