Error: itab is a table without a header....

[Former Member]

Hi everybody,

i get the following error after activation:

"ITAB" is a table without a header line and therefore has no component called "NUM"..

How can i solve this problem?

  TYPES: BEGIN OF i_itab,
           NUM TYPE I,
         END OF i_itab.
         
  DATA: itab TYPE TABLE OF i_tab.
 
  LOOP AT myTable INTO ls_mytable.

    itab-num = ls_mytable-nr.
    APPEND itab.

  ENDLOOP.

regards,

Sid

here itab is just an standard internal table

if you want to access its content like compair its value u must externally add a work area to it

itab LIKE <itab type> WITH HEADER LINE.

           NUM TYPE I,
         END OF i_itab.
         
  DATA: itab TYPE TABLE OF i_tab-.
  DATA: WA LIKE LINE OF itab.      "--> Add this 
 
  LOOP AT myTable INTO ls_mytable.
 
    wa-num = ls_mytable-nr.
    APPEND wa to  itab.       "--> Add this 
    CLEAR wa.                      "--> Add this

Have a work area for the internal table itab. Code modified below :

TYPES: BEGIN OF i_itab,

NUM TYPE I,

END OF i_itab.

DATA: itab TYPE TABLE OF i_tab,

wa TYPE i_tab.

LOOP AT myTable INTO ls_mytable.

wa-num = ls_mytable-nr.

APPEND wa to itab.

ENDLOOP.

Hope this helps.

Hi Sid,

There is a simple solution to your problem.

Have a look.

TYPES: BEGIN OF i_itab,
           NUM TYPE I,
         END OF i_itab.
         
  DATA: itab TYPE TABLE OF i_tab with header line. "Just add the addition 'with header line' 
 
  LOOP AT myTable INTO ls_mytable.
 
    itab-num = ls_mytable-nr.
    APPEND itab.
 
  ENDLOOP.

Hope this helps.
