Handling Interaction

Use

ALV output is not just used to display data structures as tables to users. Users can also use ALV output interactively in various ways. You can provide the following options:

Standard ALV Functions

In the Settings dialog box or the toolbar, you can show or hide various UI elements with which the user can access the ALV output services.

Example

ALV supports the selection of standard functions: If, for example, your ALV output does not contain any columns with values that can be calculated, the UI elements for calculation are not displayed in the columns.

User-defined, application-specific functions

You create UI elements in the toolbar with which the user can run the functions you programmed or standard ALV functions, and thus use your application effectively.
