How to increase the alv grid size dynamically

Question

Hi all,
I have to develop the report with the following requirement:
I have to take bwkey from t001k on basis of bukrs and bwkey. this bukrs and bwkey are entered in selection-screen.
I have to select matnr, lbkum, salk3 from mbew on basis of bwkey in selection-screen.(this is select options)
now the ouput should be as follows:
for example :
                    ef01                efo2               ef03
matnr     lbkum  salk3  lbkum    salk3      lbkum  salk3         total
700001     3       4            0        0            0            0                    7
700010     0       0            2       1             0            0                    3
The output should be as mentioned above.
In the above output,
in the first record for 700001, the total of 3 and 4 is displayed as total 7 and
for 700010 , it is displayed as 3.
the get the output as above in the alv grid,
I have taken bwkeys in t001k and remaining fields from mbew and joined them in final internal table.
now in the final table ifinal, i have the following fields,
matnr lbkum salk3 bwkey total.
now when i want to display the output, it is displaying as normal output like
mantr bwkey lbkum salk3 total
700001 etap   3         4      7
700002 etap   1        2       3
but i want to display in the first mentioned format.
so i tried to attach the bwkey values in it001k(this is internal table for t001k) for the final field catalog so that this bwkeys are displayed as column headings in the final output. but it is not displaying.
Please suggest me the solution to display the output in the above first mentioned
format as soon as possible
points will be awarded.
thanking u in advance.

hi ,
u can set the row count to any number , here I am setting it to 5 using the method set_visible_row_count
1 Change the visible row count to u20185u2019
  DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.
  lo_cmp_usage =   wd_this->wd_cpuse_alv( ).
  IF lo_cmp_usage->has_active_component( ) IS INITIAL.
    lo_cmp_usage->create_component( ).
  ENDIF.
  DATA lo_interfacecontroller TYPE REF TO iwci_salv_wd_table .
  lo_interfacecontroller =   wd_this->wd_cpifc_alv( ).
    DATA lo_value TYPE REF TO cl_salv_wd_config_table.
    lo_value = lo_interfacecontroller->get_model(
    lo_value->if_salv_wd_table_settings~set_visible_row_count( '5' ).
