Hello Saritha

The correct statement would be:

DATA:
  itab   TYPE ztable OCCURS 0 WITH HEADER LINE.

However, using header lines is a sign of ppor ABAP programming. Do no use them anymore, they mess up any program.

Instead, use table types and work area as shown below:

DATA:
  gt_itab     TYPE STANDARD TABLE OF ztable,  " table type
  gs_line     TYPE ZTABLE.                                 " work area

  LOOP AT gt_itab INTO gs_line.
  ...
  ENDLOOP.

Regards

Uwe

For Better coding Standard :

Internal table with header line :

data : begin of itab occurs 0,

fld1 type c,

fld2 type c,

end of itab.

Internal table without header line :

Declare Structure

types : begin of ty_itab,

fld1 type c,

fld2 type i,

end of ty_itab

Internal table without header line

data i_itab type standard table of ty_itab

Work area

data wa_itab like line of i_itab.

Try to use always Internal table without header line.

Hope you got my point and please let me know if you have any question

Thanks
