I can't understand your request, what does "Initialize sy-tabix" mean?

That system variable has the index of the current record while looping an internal table, so what do you really need to do?

Move the content of sy-yabix into a local varaibel lv_tabix and clear this lv_tabix in side the loop.

loop at itab.

lv_tabix = sy-tabix.

clear lv_tabix.

Use lv_tabix in place of sy-tabix

endloop.

GOOD

Read TABLE and Modify

read table t_vbap

with key ps_psp_pnr = t_tab-pspnr binary search.

t_vbap-kunnr = w_kunnr.

modify table t_vbap index sy-tabix.

sy-tabix is the index number of the currently processed row for an internal table.

you can initialize the sy-tabix using if loop.

THANKS

Never try to refresh or initialize system variable. It shall always lead to errors in the programs. For this I have an alternative way below.

Please declare a variable for e.g

data: <b>l_count</b> type sy-tabix.

Inside loop you can write the code like this:

say for eg. you need to refresh l_count for every new material.

Loop at itab.

on change of itab-material.

clear : l_count.

endon.

l_count = l_count + 1.

......

endloop.

Hope this clarifies your issue.

LOOP AT IT_VBRK.

    CTAB = SY-TABIX.

    LOOP AT IT_T001 WHERE BUKRS = IT_VBRK-BUKRS.

      IF SY-SUBRC  = 0.
        IT_VBRK-BUTXT = IT_T001-BUTXT.
        MODIFY IT_VBRK INDEX CTAB.
        CLEAR CTAB.
      ENDIF.

    ENDLOOP.

  ENDLOOP.

Check the code above which helps u on Sy-TABIX

Hi,

what do you mean by refresh/initialize?

please be more clear..

data: l_index type sy-tabix.
Loop at itab.

l_index = sy-tabix.
.......
.....

clear l_index.

endloop.
