FIELD-SYMBOLS: TYPE lvc_s_fcat.
* Select data
SELECT * FROM sflight
INTO TABLE i_flight
UP TO 100 ROWS.
IF sy-subrc = 0.
* Get field catalog
CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
EXPORTING
i_structure_name = 'SFLIGHT'
CHANGING
ct_fieldcat = i_fields
EXCEPTIONS
inconsistent_interface = 1
program_error = 2
OTHERS = 3
.
IF sy-subrc = 0.
*   Changing the style of field catalog

IF sy-tabix > 4.
-style = ALV_STYLE_FONT_ITALIC.

ENDIF.
ENDLOOP.
  ENDIF.
