Replace the "data: it type it_line."

With

data : it like it_line occurs 0 with header line.

Hi,

Declare your internal table as below :

tables: spfli.

types: begin of it_line,
carrid type s_carrid,
connid type s_conn_id,
end of it_line.

data : it_tt type like it_line occurs 0 with header line.

Thanks,

Sriram Ponna.
