Formerly, users could choose between a wide range of user interfaces. These included SAP Portal, Business Server Page solutions, HTML5 Apps, SAP Web Dynpro, and SAP GUI. The standard SAP GUI menu offers a wide range of access points for different objects, such as project, network, or documents. Each individual object has its own search template. It is not possible to search across all objects. If you want to define your own search, you do this on the SAP GUI using an SAP Query. SAP Business Client, which was called SAP Netweaver Business Client in older releases, attempts to solve these problems. It does so by providing a new interface and serving as an alternative to the applications used formerly.

With SAP Business Client, SAP provides users with a new interface that they can use alongside the SAP GUI, SAP GUI for HTML, NetWeaver Portal, SAP Web Dynpro or Business Server Page solutions. It can be used locally, installed on a PC, or as an internet scenario.
SAP Business Client can be used for the SAP GUI as an SAP Fiori launchpad or for Web Dynpro scenarios, such as the ones used in SAP Portfolio and Project Management.
Control Center
The user interface of the SAP Business Client offers:
A central point of access for all users
An overview of:
Transactions
Object searches
Favorites
Personal Worklists
After logging on to the system, the first thing you see is the Control Center. In both the local and internet-based SAP Business Client, the Control Center has a navigation pane containing the role assigned to the user. Each entry contains the individual work areas for project activities related to logistics or controlling.

Alternatively, you can access the SAP Fiori launchpad in the SAP Business Client and start the HTML5 transactions there.This offers you the advantage that also SAP GUI transaction work that are not (fully) SAP HTML Gui enabled like the Project Planning Board. Additionally the SAP Business Client uses the full screen width without letterboxing when rendering SAP GUI transactions compared to the SAP Fiori Launchpad in the browser. As you access your system via the SAP Fiori Launchpad you're able to also use the new SAPUI 5 apps besides the classical SAP GUi transactions.
