how can we clear Parameters fields and a Select-Options fields at runtime?

i have a parameter field for displaying plant and one select-option for displaying corresponding Materials.

if the user change the Plant, i want to clear the Select-options field.

how it is possible?

Hi,

For parameters :

clear <field>.

for select-options :

refresh <field>.clear <field>.

Hi,

Clear and refresh statements would do for parameters and select-options respectively. But if you want these to get impacted in the screen then you need clear and refresh in

AT SELECTION-SCREEN OUTPUT event.

Thanks and regards,

Hi,

Check the below code.

parameters: p_num type i.

select-options: s_num for p_num.

at selection-screen.

refresh s_num.

if not p_num is initial.

do p_num times.

s_num-low = sy-index.

append s_num.

enddo.

endif.

start-of-selection.

write:/ 'Hi'.

loop at s_num.

write:/ s_num-low.

endloop.
