problem with loop statement

Former Member — Tue, 29 Sep 2009 17:32:43 GMT

Dear friends,

Tables : J_1iexcdtl, j_1igrxsub.

exnum  exyear  matnr              zeile    exc_zeile            mblnr
          90005    2009     AA      01          01          4500001
                                                             4500002
          
          90005    2009     AB       02          02

          90005    2009     AC       03          03          4500007
                                                             4500008

This is the final output I need.But I am getting below output.

exnum  exyear  matnr              zeile    exc_zeile            mblnr
          90005    2009     AA      01          01          4500001
                                                             4500002
          
 

          90005    2009     AC       03          03          4500007
                                                             4500008

select * from  J_1iexcdtl into corresponding fields of table it_exe
                   where exnum in s_exnum and exyear in s_exyear.

 if not it_exe[] is initial.
select * from  j_1igrxsub into corresponding fields of table it_sub 
  for all entries in it_exe where exnum = it_exe-exnum and mjahr = it_exe-exyear.
endif.

loop at it_exe into wa_exe.
loop at it_sub into wa_sub where exnum = wa_exnum
                                and exc_zeile = wa_exe-zeile.
move-corresponding wa_exe to wa_final.
move  : wa_sub-mblnr to wa_final-mblnr.
append wa_final to it_final.
clear : wa_exe,wa_sub.
endloop.
endloop.

please suggest some idea.

Regards,

Bathri

Hi,

Try like this


loop at it_exe into wa_exe.
move-corresponding wa_exe to wa_final.
read table it_sub into wa_sub with key exnum = wa_exnum
                                and exc_zeile = wa_exe-zeile.
if sy-subrc = 0.
move  : wa_sub-mblnr to wa_final-mblnr.
endif.
append wa_final to it_final.
clear: wa_exe,wa_sub.
endloop.

Instead of nested loops use read to increase performance

or if you have M:M relation between the internal tables, use nested loops as its unavoidable


loop at it_exe into wa_exe.
move-corresponding wa_exe to wa_final.
loop at it_sub into wa_sub where exnum = wa_exnum
                                and exc_zeile = wa_exe-zeile.
move  : wa_sub-mblnr to wa_final-mblnr.
append wa_final to it_final.
clear: wa_exe,wa_sub.
endloop.
endloop.

Dear Vikranth,

This is the second tabix.

exnum exyear matnr zeile exc_zeile

90005 2009 AB 02 SPACE

Sorry in the original I couldnt able to edit.

In the second table there is no exc_zeile .

But I want to display the material.

Please Tell some idea.

Hi,

Then remove just that condition in the second loop and try


loop at it_exe into wa_exe.
move-corresponding wa_exe to wa_final.
loop at it_sub into wa_sub where exnum = wa_exnum.  "remove where on exc_zeile
move  : wa_sub-mblnr to wa_final-mblnr.
append wa_final to it_final.
clear: wa_exe,wa_sub.
endloop.
endloop.

Regards,

Vikranth
