* Internal table for field catalog info

DATA: i_fields TYPE lvc_t_fcat.

* Field symbol for field catalog

FIELD-SYMBOLS: <wa_fields> 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
