Changing Cell Content 

The user can use the following UI elements to change data directly in the ALV output:

·        InputField (see InputField)

·        CheckBox (see CheckBox)

·        DropDown list box BY_KEY (see DropDownByKey)

The cross-references listed above refer to generally usable Web Dynpro objects. Instead of the class names specified there, you use the class names listed below for the ALV configuration model:

Classes for Interactive UI Elements

UI Element	Class
InputField	CL_SALV_WD_UIE_INPUT_FIELD
CheckBox	CL_SALV_WD_UIE_CHECKBOX
Dropdown list box	CL_SALV_WD_UIE_DROPDOWN_BY_KEY

These classes can be found in the system in the package SALV_WD_CONFIG.

For information on displaying one of the UI elements in a cell, see Assigning Properties to Columns and Cells.

You have to switch off the write-protection in order for the user to be able to use the UI elements listed here. You must also make sure that the ALV output is activated (see Write-Protection and Activation).
