SAP BW/4HANA is SAP’s data warehouse built for SAP HANA. It supports data acquisition, modelling, transformation and enterprise reporting with governed data flows.
BW/4HANA is a warehouse application on HANA; Datasphere is a cloud data fabric with a different operating model.
A practical SAP BW/4HANA engagement begins with an inventory of the installed product and release, affected business processes, connected systems and decision-makers. From there, the team can define scope, data and integration requirements, testing responsibilities and a realistic transition or support plan.
