Components for Web Interfaces

Definition

The different components in Web interfaces are used for the following purposes:

· To offer the end user of a Web application operating elements with which the application can be controlled.

· To establish a connection between the planning objects created in the planning environment and the Web interface.

Each component has a number of properties with whose values you can determine the behavior of a specific Web application.

Structure

The following table gives a brief overview of the components available and their usage. There is a more detailed description for every attribute in the attribute editor of the Web Interface Builder in the F1 help.

Type	Use
Application	Initial element of a Web interface. Contains central properties of the application such as your URL, the package used, and settings for the Web server.
Page	Represents an HTML page of the Web application. A Web application can contain one or several pages. Pages have attributes which influence the arrangement of the elements on the page, control their appearance, and determine the page context (stateless or stateful).
Send pushbutton	Sends the entries and settings which were made in the Web application to the server. Changed data is saved in the BW-BPS internal buffer, but not in the database.
Exit pushbutton	Closes the Web application and ends the connection to the Web server.
Function pushbutton	Triggers the execution of a planning function with a specific parameter group.
Navigate pushbutton	Enables the navigation between the pages of a Web application which has several pages.
Save pushbutton	Sends the entries and settings which were made in the Web application to the server. Changed data is saved persistently in the database.
Container	Invisible element to group lower-level elements.
Group	Visible element to group lower-level elements. Contains a heading as well as an invisible grid to arrange the lower-level elements in a table layout.
Tabstrip	Is used as a higher-level element of tabs, to which further components can be arranged.
Tab	Contains a number of other components. The individual tabs within a tabstrip component are independent of each other.
Planning layout	Table with editable cells which represents a planning layout of manual planning. Used to display and enter data.
Hyperlink	Text with assigned link target (URL)
Text	Static text.
Selectors: Function/layout, package, variable value	Assignment elements which establish the technical connection between the Web interface and planning objects. Either visible or invisible.
Chart	Enables the graphical output of plan data in the form of different diagram types (for example, bar chart, and pie chart).
Error output	Determines the position on HTML page where system error messages are issued. If there are no error messages, then this error output is invisible.
