Code:
DATA: lr_salv TYPE REF TO if_salv_gui_table_ida.
DATA: lr_fcat TYPE REF TO if_salv_gui_field_catalog_ida.
TRY.
cl_salv_gui_table_ida=>create(

RECEIVING
ro_alv_gui_table_ida = lr_salv ).
CATCH cx_salv_db_connection.
CATCH cx_salv_db_table_not_supported.
CATCH cx_salv_ida_contract_violation.
ENDTRY.
* Get the field catalog reference
lr_fcat = lr_salv->field_catalog( ).
* Get all the fields
lr_fcat->get_available_fields(
IMPORTING
ets_field_names = DATA(lt_field) ).
* Delete few fields as needed
LOOP AT lt_field ASSIGNING FIELD–SYMBOL(<fs_field>).
IF <fs_field> = ‘SEATSMAX_B’ OR <fs_field> = ‘SEATSOCC_B’
OR <fs_field> = ‘SEATSMAX_F’ OR <fs_field> = ‘SEATSOCC_F’.
DELETE lt_field INDEX sy–tabix.
ENDIF.
ENDLOOP.
* Set back the fields to be displayed
TRY.
