Why does my internal table(with header line) ignore 4 of its fields?

Hi Gurus,

I am a newbie to ABAP how has spent far to much of my weekend time trying to solve the following problem;

when trying to insert data from table cdpos into my internal table, I only get the two object* fields, the other 3 are not even part of the internal table according to the debugger.

my select code is:

-

SELECT fname tabkey changenr objectclas objectid

FROM cdpos

INTO CORRESPONDING FIELDS OF i_cd_index

WHERE tabname = 'XXX'

AND fname = 'XXX'

AND chngind = 'U'

ENDSELECT.

IF sy-subrc <> 0.

ENDIF.

-

- If I use a wa like line of i_cd_index the other fields will show up.

- I have tried with including 'TABLE' in the INTO statement, same result.

Please help out, getting very frustrated here....
