Select options values pass to function module

Question

Hi all,
        I want to pass the values entered in the select options to the function module. How should my function module interface be declared for passing the select options
I tried declaring like
t_range type data in the tables tab.  But this throws error. 
Please let me know how to pass select option values back to function modules.
Thanks,

Hi,
Check this code.
data: node_flights type ref to if_wd_context_node.
data: rt_carrid type ref to data.
data: rt_connid type ref to data.
data: isflight type table of sflight.
data: wsflight type sflight.
field-symbols: <fs_carrid> type table,
<fs_connid> type table.
Retrieve the data from the select option
rt_carrid = wd_this->m_handler->get_range_table_of_sel_field(
i_id = 'S_CARR_ID' ).
if rs_carrid is not initial.   Here you can check that if rs_carrid is no initial then assign value of field symbol
Assign it to a field symbol
assign rt_carrid->* to <fs_carrid>.
endif.
Retrieve the data from the select option
rt_connid = wd_this->m_handler->get_range_table_of_sel_field(
i_id = 'S_CONN_ID' ).
if rt_connid is not initial. Here you can check that if  rt_connid is no initial then assign value of field symbol
Assign it to a field symbol
assign rt_connid->* to <fs_connid>.
endif.
if  <fs_connid> is not initial and <fs_carrid> is not initial.
Retrieve that data from the database. Normally it is suggested to
encapsulate the data retrieval in a separate class.
For simplicity, the SELECT statement has been implemented here.
clear isflight. refresh isflight.
select * into corresponding fields of table isflight from sflight
where carrid in <fs_carrid>
and connid in <fs_connid>.
endif.
Bind the data to the context
node_flights = wd_context->get_child_node( name = `FLIGHTS` ).
node_flights->bind_elements( isflight ).
Hopes this will helps you.
