As standard, the cells of the ALV display are displayed with cell editors, for example the TextView, which are not ready for input. If you want to make the ALV editable then you have the option to replace these cell editors with the following interactive interface elements:

  • InputField

  • Checkbox

  • ToggleButton

  • TriStateCheckBox

  • DropDownByKey
