ALV Grid Control - Dropwdown / Checkbox

Hello everybody,

i am using an ALV Grid Control as input table. One field is a dropdown box. Unfortunately selecting a new value at the dropdown box dose not trigger PAI, thus it does not update the output table. Is there any way to achive this? Because right now everytime you select a new value at the dropdown box you have to press the refresh button which does the update of the output table.

The same problem i do have with a checkbox in the ALV Grid control.

best regards,

Markus
