linking 2 loops

Former Member — Tue, 24 Mar 2009 05:07:55 GMT

Hi Experts..............

i have used the first loop to delete the document with the condition as '101,

and in next loop it has the details such as decription quantity etc etc.....

and my second loop (it_lips to wa_lips) only has the final table to be populated in

my ALV....

My requirement is that i want to link the first loop and the next loop in such a way

that watever document number is there, in my first loop that alone has to go to next loop to

fill the field rest should not come,

I have added this peice of code in loop it_lips further to check and update which satisfies

the loop it_vbfa i dont know how to do....

read table it_vbfa into wa_vbfa with key vbeln = wa_lips-vbeln.

if sy-subrc = 0.

wa_final-vbeln = wa_lips-vbeln.

Endif.

I dont know how to link and make the updation....

Pls do help me out

Thanx in advance

Rachel

Code as follows

=======================

*****For deleting movement typ 101

loop at it_vbfa into wa_vbfa where bwart = '101'.

delete it_vbfa where vbelv = wa_vbfa-vbelv .

Endloop.

*******Final looping

loop at it_lips into wa_lips .

read table it_vbfa into wa_vbfa with key vbeln = wa_lips-vbeln.

if sy-subrc = 0.

wa_final-vbeln = wa_lips-vbeln.

Endif.

read table it_ekpo into wa_ekpo with key ebeln = wa_lips-vgbel.

If sy-subrc = 0.

wa_final-recp = wa_ekpo-werks.

wa_final-rec = wa_ekpo-lgort.

read table it_likp into wa_likp with key vbeln = wa_lips-vbeln.

If sy-subrc = 0.

wa_final-stno = wa_likp-vbeln.

Endif.

Append wa_final to it_final.

Endloop.

clear: wa_vbfa, wa_final.

Hi,

in such cases we usually go for parallel curosor method:

Eg:

loop at it_vbfa into wa_vbfa where bwart = '101'.

delete it_vbfa where vbelv = wa_vbfa-vbelv .

loop at it_lips into wa_lips WHERE vbeln = wa_vbfa-vbeln.

do required calculations here for final looping.

endloop. "Exit for it_lips

endloop. "exit for it_vbfa

Hope it helps!!

Pavan

hey what u want exactly...

u want only the records present in it_vbfa.....?

m i right?

if s then

loop at it_vbfa into wa_vbfa where bwart = '101'.

delete it_vbfa where vbelv = wa_vbfa-vbelv .

loop at it_lips into wa_lips .

read table it_vbfa into wa_vbfa with key vbeln = wa_lips-vbeln.

if sy-subrc = 0.

wa_final-vbeln = wa_lips-vbeln.

Endif.

read table it_ekpo into wa_ekpo with key ebeln = wa_lips-vgbel.

If sy-subrc = 0.

wa_final-recp = wa_ekpo-werks.

wa_final-rec = wa_ekpo-lgort.

read table it_likp into wa_likp with key vbeln = wa_lips-vbeln.

If sy-subrc = 0.

wa_final-stno = wa_likp-vbeln.

Endif.

Append wa_final to it_final.

Endloop. -

for it_lips

Endloop.----for vbfa.

clear: wa_vbfa, wa_final.

i have the required document number in my first loop after deletion

i want to modify only in the second loop such that it has to fetch the details

only for my first loop doc number ....other doc no should not get append to my final

table , which is the problem iam currently facing.............

Hi,

Try to use for all entries.

According to me the logic would be:

1. Create final table with the final fields which u want in ur ALV display.

2. fetch all fields by using for all entries.

Check out the syntex of for all entries from SDN.

and for field from loop1 alone move to next use 'Transporting fields'.

Cheers,

Rudhir

sorry monica the one u have specified is not satisfying......iam getting double the record items

Re: linking 2 loops

hi:

you have 2 ways like

1. keep master table a main loop and under it, the item loop would be there for further processing.

2. by using join, you can select only fields which is required for final table

Where the relationship is concerned, please find the link

hi rudhir...

thanx for the reply

i want to know only this part

and for field from loop1 alone move to next use 'Transporting fields'.

how to do in the next loop???

Re: linking 2 loops

Former Member — Tue, 24 Mar 2009 05:35:58 GMT

hi,

define third it and then move ur first it data into third it using tansporting fields and then loop it with ut second table.

Former Member — Tue, 24 Mar 2009 05:41:41 GMT

Hi Rachel...

Change the read statemnt which i have given..and check out..


read table it_vbfa into wa_vbfa with key vbeln = wa_lips-vbeln.
if sy-subrc = 0.
wa_final-vbeln = wa_lips-vbeln.
else.
continue.
Endif.

I have added 'ELSE' and 'CONTINUE'.

..cheers..

Hi Rachel,

Sorry actually i thought u need only one fields from loop1. Transporting fields will not work. By using for all entries only u can solve ur problem.

Dont use loop inside loop. It decreases the performance.

*****For deleting movement typ 101 """" According to me this section is OK

loop at it_vbfa into wa_vbfa where bwart = '101'.

delete it_vbfa where vbelv = wa_vbfa-vbelv .

Endloop.

'''''''''''''''''''''''''Now u want the data in final table according to the vbelv in first table.

*******Final looping

SORT it_vbfa by vbeln.

loop at it_lips into wa_lips .

read table it_vbfa into wa_vbfa with key vbeln = wa_lips-vbeln.

''''''''' the whole code should come under the block so that it should fetch the only data relevent to vbeln of loop1. """"""""""""""""""""""""""""""

************************block B1 started with IF********************

if sy-subrc = 0.

wa_final-vbeln = wa_lips-vbeln.

read table it_ekpo into wa_ekpo with key ebeln = wa_lips-vgbel.

If sy-subrc = 0.

wa_final-recp = wa_ekpo-werks.

wa_final-rec = wa_ekpo-lgort.

read table it_likp into wa_likp with key vbeln = wa_lips-vbeln.

If sy-subrc = 0.

wa_final-stno = wa_likp-vbeln.

Endif.

Append wa_final to it_final.

Endif.

************************block B1 ENDED with ENDIF********************

Clear wa_final, wa_vbfa.

Endloop.

hope this will help u.

Hi,

if you code it like in my earilier thread...i hope it will meet your requirement.

Eg: LOOP AT it_vbfa INTO wa_vbfa.

LOOP AT it_lips INTO wa_lips where vbeln = wa_vbfa-vbeln.

wa_final-vbeln = wa_vbfa-vbeln.

similarly move the other field values to ur final wa structure and append it to final internal table.

append wa_final to it_final.

clear : wa_lips, wa_final.

ENDLOOP.

Hope it works!!

take a look of this . one of thesimplest code.

first define onefinal table like


TYPES : BEGIN OF TY_REPORT,
        KUNNR LIKE VBAK-KUNNR, "    Customer No.
        NAME1 LIKE KNA1-NAME1, "    Customer Name.
        KDAUF LIKE AFPO-KDAUF, "    Sales Order No.
        DWERK LIKE AFPO-DWERK, "    Plant
        AUFNR LIKE AFKO-AUFNR, "    Production Order No.
        MATNR LIKE AFPO-MATNR, "    Material
        MAKTX LIKE MAKT-MAKTX, "    Material Desc
        GAMNG LIKE AFKO-GAMNG, "    Target Qty
        IGMNG LIKE AFKO-IGMNG, "    Confirm QTY
        OPEN_QTY LIKE AFKO-GAMNG, " Open Order Qty
        END OF TY_REPORT.



*&---------------------------------------------------------------------*
*& Internal tables         Begin with it_
*&---------------------------------------------------------------------*
DATA : IT_REPORT type TY_REPORT OCCURS 0 WITH HEADER LINE.

then fetch all data using for all entries like


 SELECT * FROM VBAK INTO TABLE IT_VBAK
      WHERE   KUNNR IN SO_KUNNR
      AND  ERDAT IN SO_DAT1.
      IF SY-SUBRC EQ 0.

        SELECT * FROM KNA1 INTO TABLE IT_KNA1
          FOR ALL ENTRIES IN IT_VBAK
          WHERE KUNNR = IT_VBAK-KUNNR.

        SELECT * FROM AFPO INTO TABLE IT_AFPO
           FOR ALL ENTRIES IN IT_VBAK
           WHERE KDAUF = IT_VBAK-VBELN.

        SELECT * FROM AFKO INTO TABLE IT_AFKO
           FOR ALL ENTRIES IN IT_AFPO
           WHERE AUFNR = IT_AFPO-AUFNR .

        SELECT * FROM MAKT INTO TABLE IT_MAKT     " Get Raw Material Desc
            FOR ALL ENTRIES IN IT_AFPO
            WHERE MATNR = IT_AFPO-MATNR.

and then do looping simply like


  LOOP AT IT_AFPO.
    READ TABLE IT_VBAK WITH KEY  VBELN = IT_AFPO-KDAUF.
    IT_REPORT-KUNNR = IT_VBAK-KUNNR.
    IT_REPORT-KDAUF = IT_AFPO-KDAUF.
    IT_REPORT-DWERK = IT_AFPO-DWERK.
    IT_REPORT-AUFNR = IT_AFPO-AUFNR.
    IT_REPORT-MATNR = IT_AFPO-MATNR.

    READ TABLE IT_KNA1 WITH KEY KUNNR = IT_VBAK-KUNNR.
    IT_REPORT-NAME1 = IT_KNA1-NAME1.

    READ TABLE IT_MAKT WITH KEY MATNR = IT_AFPO-MATNR.
    IT_REPORT-MAKTX =   IT_MAKT-MAKTX.

    READ TABLE IT_AFKO WITH KEY AUFNR = IT_AFPO-AUFNR.
    IT_REPORT-GAMNG = IT_AFKO-GAMNG.
    IT_REPORT-IGMNG = IT_AFKO-IGMNG.

    OPEN_QTY1 = IT_AFKO-GAMNG - IT_AFKO-IGMNG.

    IT_REPORT-OPEN_QTY = OPEN_QTY1.

    SORT IT_REPORT.

    IF IT_REPORT-OPEN_QTY > 0.
      APPEND IT_REPORT.

hope u will get idea.

thanks for the reply , i tried the code but then when it goes to the second loop my sy-subrc = 4

thou

read table it_vbfa into wa_vbfa with key vbeln = wa_lips-vbeln. has a value from first loopp value

Re: linking 2 loops

Former Member — Tue, 24 Mar 2009 06:21:31 GMT

Rachel...

I guess thats fine.. are you getting the correct output ??

and yeah..one more thing..rachel..

Clear the WA_FINAL and WA_VBFA....before the ENDLOOP statement.... this is jus good programming practice.. so now they will not have values of first loop when the loop is executed for the second time..
