SAP List Viewer (ALV) is a flexible tool used to display lists and tabular structures. It provides common list operations as standard functions and can be enhanced by user-specific functions. This allows you to use ALV in a large range of application programs.
For the end user, the standard output consists of a toolbar, a title, and the output table. Users can change and make settings for the column display, more complex sorting options, aggregations, and so on, by using the additional dialog box. As a developer of the application, you have various options to define the appearance, function, and runtime behavior of this ALV output.
You can also use the ALV component. You include this component in the component of your application (as with all other predefined components). You therefore have all the resources required to provide users of your application with a powerful tool for displaying lists.
Features
The ALV component is partly based on the Web Dynpro table UI element. Many of the properties of the table element are therefore supported. This includes the use of different cell editors, background colors, and size specifications. The following options are also available:
● You specify which columns are contained in the user's column set, and which of these are visible in the ALV output.
● You can sort and filter the values of the ALV output, and perform calculations.
● You decide whether and to what extent the ALV output can be edited.
● You specify which UI elements in the cells display the values of the columns.
● You provide the UI elements in the toolbar, with which the user can perform application-specific functions.
● You specify whether and how user interactions are handled in the ALV output.
● The user can save settings in different views.
● You can configure special areas above and below the ALV output.
● And much more…
You can find the basic sample component WDT_ALV in your system in package SWDP_DEMO, subpackage SWDP_DEMO_TUTORIALS.
