Itab manipulation

Former Member — Wed, 17 Mar 2010 14:00:13 GMT

Hi all,

I have an itab filled with the following values.

This itab contains quantities of a particular material(100) sold to different lands in a period of time

The user enters a period from Oct2009 - Mar2010.

Sorted my itab1 by matr land month.

MatNr Land  month  quantity

100    A    01.10     5
100    A    02.10     4
100    A    03.10     5
100    A    09.10     5
100    B    12.09     5
100    C    11.09     4

For the user entered range of Oct2009 - Mar2010

These months are calculated and stored in a structure below:

TYPES : BEGIN OF gty_monthcalc,
          month TYPE  c length 30,
        END OF gty_monthcalc.

DATA gt_monthcalc TYPE TABLE OF gty_monthcalc.
DATA gs_monthcalc LIKE LINE OF gt_monthcalc.

In my example the range was between 
03.11.2009 - 05.03.2010.

So the gt_monthcalc contains the following  months.

11.09
12.09
01.10
02.10
03.10

So Now I have to go through the itab1 and write the quantities for each land in the order(Nov to march) into a string and use the "write" statement to write the string out.

Now the problem Iam facing here is the months which are there in gt_monthcalc itab and which are not there in the itab1 for each land I have to add a new line to the itab and write it out.

For example:-
100    A    11.10     0
100    A    12.10     0

and for other lands as well which doesnt contain the months in gt_monthcalc itab.

What is the optimal way to do it....

Thanks

Roughly & ugly (of course don't use heade lines...):

DATA :itab2 TYPE table of ty_itab1,
 itab3 TYPE TABLE of ty_itab1.

SORT itab1 BY matnr land period.
itab2[] = itab1[].
DELETE ADJACENT DUPLICATES FROM itab2 COMPARING matnr land.
LOOP AT itab1.
  LOOP at gt_month.
    READ TABLE itab1 TRANSPORTING NO-FIELDS
       WITH KEY matnr = itab1-matnr
                       land = itab1-land
                         period = gt_month-period BINARY search.
    IF sy-subrc = 0.
     "hurray already in
      CONTINUE.
     ELSE.
      " no sales...
     itab3-land = itab1-land.
     itab3-matnr = itab1-matnr.
     itab3-period = gt_months-period.
     itab3-sales = 0.
     APPEND itab3.
  ENDIF.
 ENDLOOP.
ENDLOOP.
IF sy-subrc = 0.
APPEND LINES OF itab3 TO itab1.
FREE: itab2, itab3.
ENDIF.

Then you have all (& still too much) data in itab1.

the rest shoul be clear...

Re: Itab manipulation

Hi,

Easiest way is to collect all possible material and Land info in another itab.

Then start to loop in that table. ( Use this table as a key ) gt_mat_land

loop at gt_mat_land.

loop at gt_monthcalc.

clear my_itab1.

read table my itab1 with key matnr = gt_mat_land-matnr

land = gt_mat_land-land

month = gt_monthcalc-month.

if sy-subrc = 0.

move-corresponding my_itab1 to itab_final.

else.

move gt_mat_land-matnr to itab_final-matnr.

move gt_mat_land-land to itab_final-land.

move gt_monthcalc-month to itab_final-month.

endif.

collect itab_final.

endloop.

itab_final will have all the vlues with 0 amounts for all mats lands and months. Then you can write or use in ALV.

Marcin,

I just ran the code.

The output is not right

Land "A" already has these quantities filled in

100    A    01.10     5
100    A    02.10     4
100    A    03.10     5
100    A    09.10     5

The quantity for month which are not there in gt_monthcalc itab for Land "A" is oct,nov and december.so there should be 3 for lines added to itab for land A

like along with the existing ones.....

100    A    10.09     0
100    A    11.09     0
100    A    12.09     0

This must be true for other land as well. The months which are not there in the itab should be added with 0 quantity...

Re: Itab manipulation

MarcinPciak — Wed, 17 Mar 2010 15:48:26 GMT

Apparently there is missing one entry for OCT in gt_monthcalc.

Simply append this month


gt_monthcalc-month = '10.09'.
APPEND gt_monthcalc.

and you will get all months for each land from 10.09 - 03.10

Marcin

100                C 12.09             0,00

2 questions.

for the months which are not there atleast for "A" it is repeated thrice with 0 quantities.

should I have to delete it with "delete adjacent entries" or what is the reason for that...

Guys,

What should I do to sort the land by month so that it always goes from lower range to higher(From Nov- March)

Hello,

I have used Marcin's code as a reference & modified it :


DATA ITAB1 TYPE TT_ITAB WITH HEADER LINE.

SORT ITAB BY MATNR LAND MONTH.

ITAB1[] = ITAB[].

DELETE ADJACENT DUPLICATES FROM ITAB1 COMPARING MATNR LAND.

LOOP AT GT_MONTHCALC.
  LOOP AT ITAB1.
    MOVE-CORRESPONDING ITAB1 TO ITAB_FILL.
    ITAB_FILL-MONTH = GT_MONTHCALC-MONTH.
    CLEAR ITAB_FILL-QUA.
    APPEND ITAB_FILL.
  ENDLOOP.
ENDLOOP.

SORT ITAB_FILL BY MATNR LAND MONTH.

LOOP AT ITAB_FILL.
  READ TABLE ITAB WITH KEY
  MATNR = ITAB_FILL-MATNR
  LAND  = ITAB_FILL-LAND
  MONTH = ITAB_FILL-MONTH BINARY SEARCH.
  IF SY-SUBRC EQ 0.
    ITAB_FILL-QUA = ITAB-QUA.
    MODIFY ITAB_FILL.
  ENDIF.
ENDLOOP.

LOOP AT ITAB_FILL.
  WRITE: / ITAB_FILL-MATNR, ITAB_FILL-LAND,
           ITAB_FILL-MONTH, ITAB_FILL-QUA.
ENDLOOP.

The output looks something like this:


100        A 01.10             5,00
100        A 02.10             4,00
100        A 03.10             5,00
100        A 10.09             0,00
100        A 11.09             0,00
100        A 12.09             0,00
100        B 01.10             0,00
100        B 02.10             0,00
100        B 03.10             0,00
100        B 10.09             0,00
100        B 11.09             0,00
100        B 12.09             5,00
100        C 01.10             0,00
100        C 02.10             0,00
100        C 03.10             0,00
100        C 10.09             0,00
100        C 11.09             4,00

Thank you very much Guys....

It works perfect.

1 last question.

What should be done to sort the itab accoring to matnr,Land and month so that

the month is displayed from lowerrange to upper range (That is from Nov2009 -Mar 2010).Should I have to change the type of month to date from string.

Re: Itab manipulation

kesavadas_thekkillath — Wed, 17 Mar 2010 19:08:19 GMT

Hi,

You no need to change the type.

Check this,

SORT itab by matnr land ascending month descending.

Sort it like this

SORT itab BY matnr land month+3(2) month(2).
