FAQ. Netweaver vs NWBC
What’s the difference between SAP Netweaver and SAP Business client?
SAP Netweaver is a server that holds SAP (like portal).
SAP Business Client is a program that runs on a user desktop and replaces GUI functions in a new interface based on a web technologies.
Let’s say we can work with ESS/MSS in a browser, opening SAP portal ling or in a Netweaver Business Client (NWBC) without portal as it renders business logic in a NWBC without Netweaver Server.
