ITAB IS not Modifying.

Former Member — Thu, 05 Apr 2007 17:12:00 GMT

Hi All,

Please look at my code.I am trying to update main_itab with wf_ind field. Its pulling correct data in wfa_itab.

But its not modifying main_itab.

Any suggestion will be help ful for me.

DATA: Begin of WFA_itab occurs 0,

reference like zest1940_sfa_ptf-reference,

wf_ind like zest1940_sfa_ptf-name,

end of WFA_itab.

select reference name from zest1940_sfa_ptf into table WFA_itab

FOR all entries in main_itab where

reference = main_itab-reference and

partn_func EQ 'AP' .

loop at WFA_itab.

Modify main_itab transporting wf_ind where

reference EQ WFA_itab-reference.

append main_itab.

endloop.

Hi,

Before the modify statement move the values to the header line..

main_itab-wf_ind = <b>'pass some value'</b>.

Modify main_itab transporting wf_ind where

reference EQ WFA_itab-reference.

Thanks,

Naren

Hi,

Check this code.

*----------------------------------------------------------------------*
*----------------------------------------------------------------------*
DATA: BEGIN OF wfa_itab OCCURS 0,
        reference LIKE zest1940_sfa_ptf-reference,
        wf_ind LIKE zest1940_sfa_ptf-name,
END OF wfa_itab.

DATA: l_index LIKE sy-tabix.   *" New variable inserted

SELECT
      reference
      name FROM zest1940_sfa_ptf
      INTO TABLE wfa_itab
      FOR ALL ENTRIES IN main_itab
      WHERE reference = main_itab-reference AND
            partn_func EQ 'AP' .

*" Do not user this code
*LOOP AT wfa_itab.
*
*  MODIFY main_itab TRANSPORTING wf_ind WHERE
*  reference EQ wfa_itab-reference.
*
*  APPEND main_itab.
*ENDLOOP.

*" Instead use this code
SORT wfa_itab BY reference.
LOOP AT main_itab.
  l_index = sy-tabix.

  READ TABLE wfa_itab WITH KEY reference = main_itab-reference
                      BINARY SEARCH.

  IF sy-subrc = 0.
    main_itab-wf_ind = wfa_itab-wf_ind.
    MODIFY main_itab INDEX l_index.
  ENDIF.
ENDLOOP.
*----------------------------------------------------------------------*
*----------------------------------------------------------------------*

Let me know if you still have a problem.

Regards,

Try this.

loop at WFA_itab.

read table main_itab with key reference = WFA_itab-reference.

if sy-subrc = 0

Modify main_itab transporting wf_ind where

reference EQ WFA_itab-reference.

endif.

endloop.

Hope it works,
