SAP BW/4HANA cockpit is a Web-based interface used for administration of a BW/4HANA system. The main aim of launching an SAP Fiori app is to use SAP on the go with minimal user interaction. The app is built mainly for frequently used functions. The app helps us to perform standard SAP transaction in our mobile, view information about business objects and to measure the performance.
