Input help on ALV filters (dynpro ABAP)

Hi,

Do anyone know if it is possible to add input help on filter boxes in the ALV filters in dynpro ABAP ?

So, like on the line in the actual alv grid we see an input help option, I would like to have input help on the box above (Boxed in red), which is a filter line (added by pressing the default filter option on the ALV).

Regards,

-Tony
