Re : Internal tables

[Former Member]

Hi Guru's,

I have 2 internal tables ALV_LTB AND IT_BOM.

IN ALV_LTB i have the data like

stlal I stlnr I stlst I datuv I............

03 I 40 I - I 02.04.2008

02 I 60 I - I 03.04.2008

IN IT_BOM i have the data like this

stlal I stlnr I stlst I datuv

03 I 40 I 02 I 02.04.2008

02 I 60 I 01 I 03.04.2008

i want to modify the internal table ALV_LTB like beloow

stlal I stlnr I stlst I datuv

03 I 40 I 02 I 02.04.2008

02 I 60 I 01 I 03.04.2008

Hi You can use MOVE-CORRESPONDING..

MOVE-CORRESPONDING alv_tab TO it_bom.

Hope this helps...

Hi,

Try this......

LOOP AT IT_BOM.

LOOP AT ALV_LTB WHERE stlal = IT_BOM-stlal AND stlnr = IT_BOM-stlnr.

ALV_LTB-stlst = IT_BOM-stlst.

MODIFY ALV_LTB.

ENDLOOP.

ENDLOOP.

hi,

you may try the following approach:

loop at it_ltb into wa_ltb.
g_tabix = sy-tabix.
read table it_bom into wa_bom with key stlal = wa_ltb-stlal.
wa_ltb-stlst = wa_bom-stlst.
modify it_ltb from wa_ltb transporting stlst index g_tabix.
clear wa_ltb.
clear wa_bom.
clear g_tabix.
endloop.

loop at alv_tb into wa_alv.
read table it_bom into wa_bom with key stlal = wa_alv-stlal. "Read the corresponding entry
wa_alv-stlst = wa_bom-stlst. 
modify alv_tb from wa_alv transporting stlst. "modify the alv table
endloop.

hi praveen,

as far as i understand u want to modify the stlst value in the ALV_LTB table... right?

so..

loop at alv_ltb into ls_alv_ltb. "ls_alv_ltv is work area for alv_ltb.
    clear ls_IT_BOM.
*reading the same row of IT_BOM.
    read table IT_BOM into ls_IT_BOM with key stlal = ls_alv_ltb-stlal stlnr = ls_alv_ltb-stlnr.
    if sy-subrc = 0.
         ls_alv_ltb-stlst = ls_IT_BOM-stlst.
*modifying alv_ltb from the value we got from IT_BOM
         modify alv_tlb from ls_alv_ltb.
    endif.
    clear : ls_alv_ltb.
endloop.

i hope this helps...

Hello

LOOP AT ALV_LTB.
  READ TABLE IT_BOM WITH KEY STLAL = ALV_LTB-STLAL
                             STLNR = ALV_LTB-STLNR.
  IF SY-SUBRC = 0.
    ALV_LTB-STLST = IT_BOM-STLST.
    MODIFY ALV_LTB INDEX SY-TABIX.
  ENDIF.
ENDLOOP.

Hi,

If you use FIELD SYMBOLS, it will also improve the performance.

Declare a field symbol of type similar to that of ALV_LTB so that we can avoid MODIFY statement which will improve performance.

LOOP AT ALV_LTB ASSIGNING <FS_LTB>.

READ TABLE IT_BOM WITH KEY STLAL = <FS_LTB>-STLAL

STLNR = <FS_LTB>-STLNR.

IF SY-SUBRC = 0.

<FS_LTB>-STLST = IT_BOM-STLST.

ENDIF.

ENDLOOP.

UNASSIGN <FS_LTB>.

Thanks,
