What is Presentation Interface ?

Features of Presentation Interface .

Enterprise Resource Planning (ERP) systems integrate (or attempt to integrate) all data and processes of an organization into a unified system.

A typical ERP system will use multiple components of computer software and hardware to achieve the integration

A key ingredient of most ERP systems is the use of a unified database to store data for the various system modules.

The term ERP originally implied systems designed to plan the use of enterprise-wide resources.

ERP originated in the manufacturing environment, today's use of the term ERP systems has much broader scope.

Businesses, non-profit organizations, nongovernmental organizations, governments, and other large entities utilize ERP systems.

The SAP presentation interface will be the main point of access for all types of users of SAP systems, their business applications, and administration and development functions.

SAP provides different ways of accessing the systems or applications, such as using only an Internet browser, through the Enterprise Portal, the Business Explorer for the SAP Business Warehouse, or the most typical one, known as the SAP graphical user interface, or SAP GUI.

The SAP GUI is the program that connects the user workstations with the SAP systems.

The connection between the SAP GUIs and the SAP dispatcher is made with an optimized protocol, known as DIAG, in which small data packages are sent through the network.

The presentation interface is the component in charge of making functionally equivalent the presentation and the handling of Web AS, no matter the type of front end used.

For each user session there is a SAP process (SAP GUI) that enables the use of all available presentation possibilities of the corresponding window software.

These terminal processes are in charge of, among other things, managing the graphical elements of the Web AS system.

In the SAP R/3 system, all the menus options, the buttons, and even most of the graphical elements are inside the database.

The presentation interface allows for upload and download functions from the application server.

It also includes possibilities for file transfers and communication with popular Windows applications, including MS-Excel, MS-Word, and MS-Access. This is possible, of course, when using a Windows-based front end. Both SAP GUI for HTML and SAP GUI for Windows have this capability.

Another feature available in the presentation interface is the SAP graphic utility, which establishes a dialog between the ABAP application and the graphic utility in the presentation server for extracting data to make up graphical representations of the information.
