Try the following example

PARAMETERS: p_carr TYPE sflight-carrid,

p_conn TYPE sflight-connid.

DATA : sflight_tab TYPE STANDARD TABLE OF sflight.,

wa_sflight_tab TYPE sflight.

...

PERFORM select_sflight TABLES sflight_tab

USING p_carr p_conn.

...

FORM select_sflight TABLES flight_tab LIKE sflight_tab

USING f_carr TYPE sflight-carrid

f_conn TYPE sflight-connid.

SELECT *

FROM sflight

INTO TABLE flight_tab

WHERE carrid = f_carr AND

connid = f_conn.

if sy-subrc = 0.

read table flight_tab into wa_sflight_tab with key Airline = '0820'.

if sy-subrc = 0.

endif.

ENDFORM.

Hi deepthi chennamadhavuni,

yes it is possible if, in the form, you know table structure or field name.

FORM process_any_table CHANGING itab TYPE ANY TABLE.
  FIELD-SYMBOLS:
    <struc> TYPE ANY,
    <field> TYPE ANY.
  LOOP AT itab ASSIGNING <struc>.
    ASSIGN COMPONENT 'FIELD_N' OF STRUCTURE <struc> TO <field>.
    CHECK sy-subrc = 0.
    WRITE: / 'record', sy-tabix, 'FIELD_N value is', <field>.
  ENDLOOP.
ENDFORM.

Regards,

Clemens
