Help,Webdynpro ALV report

Question

Hello,
My Webdynpro ALV report display SFLIGHT all fields .
But I want to show only five fields,
how code?
CODE::
data:node_flights type ref to if_wd_context_node,
       it_flights type sflight_tab1,
       is_flights type sflight,
       it_final type IF_MAIN=>elements_flights,
       is_final type IF_MAIN=>element_flights.
  select * from sflight into table it_flights up to 10 rows.
  node_flights = wd_context->get_child_node( 'FLIGHTS' ).
  data:l_ref_cmp_usage type ref to if_wd_component_usage.
  l_ref_cmp_usage = wd_this->wd_cpuse_alv( ).
  if l_ref_cmp_usage->has_active_component( ) is initial.
    l_ref_cmp_usage->create_component( ).
  endif.
  data:l_ref_interfacecontroller type ref to iwci_salv_wd_table.
  l_ref_interfacecontroller = wd_this->wd_cpifc_alv( ).
navigate from <CONTEXT> to <NODE_FLIGHT> via lead selection
  node_flights = wd_context->get_child_node( name = `NODE_FLIGHT` ).
fill context node
  node_flights ->bind_table( it_flight ).
endmethod.
thanks

HI,
There is no need to change your code.
Do one thing.
Create a node SFLIGHT and do not add dictionary structure SFLIGHT.
Then create what are the required five attributes under it.
Make sure all these five refer to the dictionary data elements.
example: If you want carrid declare dectionary structure S_CARR_ID.
Like wise.
Now finally goto component usage->ALV->INTERFACECONTROLLER in the
left side tree of web dynpro component.
Then create component usage and drag SFLIGHT node to DATA of the context.
It is one of the way.
Second way is.
Create SFLIGHT node and mention SFLIGHT as stricture and select five required attributes that you need.
Now after creation of SFLIGHT NODE just delete the structure name present in the PROPERTIES of
SFLIGHT NODE.
Now finally goto component usage->ALV->INTERFACECONTROLLER in the
left side tree of web dynpro component.
Then create component usage and drag SFLIGHT node to DATA of the context.
I hope it helped you.
Regards and Best wishes.
