No Result with REUSE_ALV_LIST_DISPLAY

Hi all,

I was not able to display my table, f_flight_list after i retrieve the records using BAPI 'BAPI_FLIGHT_GETLIST'.

I tried to display only 4 fields by assigning airline,flightdate,cityto and cityfrom into f_detail2 but it still does not work.

What is wrong with the code? I have also specified IT_FIELDCAT and t_outtab.

This is the code:

parameters:

airlines like BAPISFLDAT-AIRLINEID.

type-pools: slis.

Data:

f_airline like BAPISFLKEY-AIRLINEID,

f_flight_list like table of BAPISFLDAT,

line

f_detail like line of f_flight_list,

• use f_detail2 to see the table in alv

begin of f_detail2 occurs 0,

airline like BAPISFLKEY-AIRLINEID,

flightdate like BAPISFLDAT-flightdate,

cityto like BAPISFLDAT-cityto,

cityfrom like BAPISFLDAT-cityfrom,

end of f_detail2.

*table of f_detail2

data:

display_flight like table of f_detail2,

*Define the field catalog

afield type slis_fieldcat_alv,

fieldcat type slis_t_fieldcat_alv.

line

*f_detail like line of f_flight_list.

clear afield.

f_airline = airlines.

call function 'BAPI_FLIGHT_GETLIST'

exporting

airline = f_airline

tables

flight_list = f_flight_list.

if sy-subrc ne 0.

write 'error changing order'.

else.

• output detail using line *

• Use List Display to display search result

loop at f_flight_list into f_detail.

f_detail2-airline = f_detail-airline.

f_detail2-flightdate = f_detail-flightdate.

f_detail2-cityto = f_detail-cityto.

f_detail2-cityfrom = f_detail-cityfrom.

append f_detail2 to display_flight.

• write f_detail2-airline.

endloop.
