Doubts in internal table logic

Hi All,
I have two internal table, according to the posnr value i need to add the kbetr value from the 2nd internal table and update the value in the 1st line internal table. below the example of my internal table. Here for the line item 0010 i need to calculate 10.0030.1011.00 and i need to add the value inthe 1st internal table kbeter_value. can anyone help this?
POSNR        MATNR kbetr_value
0010             abc
0020             xyz
0030             123
POSNR     KBETR
0010       10.00
0010        30.10
0010       11.00
0010       60.30
0020       12.64
0020       11.32
0030       79.46
0030       00.00
0030       45.3

Hi Mohana,
Its very simple ..you can do it in many ways....
first one is in the second internal table use collect ....
for example : 1st internal table is itab and the second is jtab .
1. In jtab u use collect stmt to calculate the posnr values .
loop at jtab.
collect jtab .           " by using this u will have 0010    111.40 in jtab
endloop.
structure of jtab will be :
0010    111.40
0020    .........
0030    ..........
2. afterwards while printing you can use read to get those :
loop at itab.
read table jtab with key posnr = itab-posnr.
if sy-subrc = 0.
itab-ksbtr-value = itab-value .
modify itab .
endif.
endloop.
Hope you got it by now...if you any problem do reply back ....
cheers,
Vishnu .

Internal table logic issue

Hi All,
I have one logical issue related to internal table manipulation.
I have one internal table :
I_DAT - This is related to Loading/Unloading of Goods.
for example with 3 fields
VSTEL, KUNNA, KMMANG.
Now suppose my data looks like this after sorting:
VSTEL   KUNNA    KMMANG
100       -        -
200       -        -
300       -        -
400       -        -
-         500      X
-         600      X
-         700      X
-         800      X
Here 100,200,300,400 are Loading points.
ANd 500,600,700,800 are unloading points.
Now what i want is For loading & Unloading points i need to pick up Address and print one after other.
But how they need to print is:
FOR INITIAL LOADING OF
ADDRESS- For 100
FIRST STOP: FOR LOADING OF
ADDRESS- For 200
SECOND STOP: FOR LOADING OF
ADDRESS- For 300
Etc .....
Then
FOR UNLOADING OF:
ADDRESS- For 400
FIRST STOP: FOR UNLOADING OF
etc.
FINAL STOP: FOR FINAL UNLOADING OF
We might get as many records :
Can any body give me the logic:
Printing Address is not a problem:
But Above every address we need to print FIRST STOP, SECOND etc like that.
For this i need logic.
Can anybody give the solution!
Thanks in advance.
Thanks & Regards,
Prasad.

Try this.I think you want output like this......
DATA: BEGIN OF LINE,
        CARRID   TYPE SBOOK-CARRID,
        CONNID   TYPE SBOOK-CONNID,
        FLDATE   TYPE SBOOK-FLDATE,
        CUSTTYPE TYPE SBOOK-CUSTTYPE,
        CLASS    TYPE SBOOK-CLASS,
        BOOKID   TYPE SBOOK-BOOKID,
      END OF LINE.
DATA ITAB LIKE SORTED TABLE OF LINE WITH UNIQUE KEY TABLE LINE.
SELECT CARRID CONNID FLDATE CUSTTYPE CLASS BOOKID
       FROM SBOOK INTO CORRESPONDING FIELDS OF TABLE ITAB.
LOOP AT ITAB INTO LINE.
AT FIRST.
    WRITE / 'List of Bookings'.
    ULINE.
ENDAT.
    AT NEW CARRID.
      WRITE: / 'Carrid:', LINE-CARRID.
    ENDAT.
      AT NEW CONNID.
        WRITE: / 'Connid:', LINE-CONNID.
      ENDAT.
        AT NEW FLDATE.
          WRITE: / 'Fldate:', LINE-FLDATE.
        ENDAT.
          AT NEW CUSTTYPE.
            WRITE: / 'Custtype:', LINE-CUSTTYPE.
          ENDAT.
               WRITE: / LINE-BOOKID, LINE-CLASS.
            AT END OF CLASS.
              ULINE.
            ENDAT.
ENDLOOP.
This is also helpful......
LOOP AT <itab>.
AT FIRST. ... ENDAT.
    AT NEW <f1>. ...... ENDAT.
      AT NEW <f2 >. ...... ENDAT.
          <single line processing>
      AT END OF <f2>. ... ENDAT.
    AT END OF <f1>. ... ENDAT.
AT LAST. .... ENDAT.
ENDLOOP.

Reg. internal table logic

Hi,
I have an internal table with 5 fields (Vbeln, A, B, C, D ) and records like this:
Record1:
Field vbeln (value is 6000000001), Field A (value is 2006), Field B (value is 1130), Field C (value is initial), Field D (value is initial)
Record1:
Field vbeln (value is 6000000001), Field A (value is initial), Field B (value is initial), Field C (value is 2005), Field D (value is 1134)
Now whenever, Field A and Field B has values, field C and field D are initial and vice versa.
I Want to get all of the field values in just one record like below when the key vbeln is same.:
Field vbeln (value is 6000000001), Field A (value is 2006), Field B (value is 1130), Field C (value is 2005), Field D (value is 1134)
I know I can create another internal table, copy the contents, use the looping logic and achieve the same but wondering if there is any better way of doing the same?
Appreciate your input.
Thanks!

Hi,
You need another internal tables. Please try this.
SORT ITAB1.
ITAB2[] = ITAB1[].
LOOP AT ITAB1.
LOOP AT ITAB2 WHERE ITAB2-VBELN EQ ITAB1-VBELN
                  AND ITAB2-DATE1 NE ITAB1-DATE1
                  AND ITAB2-TIME1 NE ITAB1-TIME1.
    ITAB3-VBELN = ITAB1-VBELN.
    ITAB3-DATE1 = ITAB1-DATE1.
    ITAB3-TIME1 = ITAB1-TIME1.
    ITAB3-DATE2 = ITAB2-DATE2.
    ITAB3-TIME2 = ITAB2-TIME2.
    APPEND ITAB3.
ENDLOOP.
ENDLOOP.

Regarding Internal table logic

Hi,
I have my internal table as follows:
DATA: BEGIN OF I_DATA OCCURS 0,
        prgname TYPE SYST-REPID,
        matnr   TYPE mara-matnr,
        berid   TYPE mdma-berid,
      END OF I_DATA.
Data that fills into can be as follows:
Ex:
PROGRAM1,1000,MRP1
PROGRAM1,1000,MRP1
PROGRAM1,2000,MRP1
PROGRAM2,1000,MRP1
PROGRAM2,1000,MRP1
PROGRAM2,2000,MRP1
PROGRAM3,1000,MRP1
PROGRAM3,1000,MRP1
PROGRAM3,2000,MRP1
It can any order in above way.
Then i will sort the above data as follows:
SORT I_DATA BY prgname matnr berid.
Now here my issue is:
DATA: t_objtxt     LIKE solisti1   OCCURS 0 WITH HEADER LINE.
I need to push the above internal table data into T_OBJTXT internal table as follows:
It should first Display program Name as Program Name: Program3, Then column heading MATNR, BERID below it and data of that program[1st] below them till all the 1st program's data finished. Whenever MATNR value changes in this program list i need to print an ***** like line. TO indicate all the materials printed.
When 2nd program comes again i have to write Program Name: Program2, Then column heading MATNR, BERID below it and data of that program[1st] below them till all the 1st program's data finished. Whenever MATNR value changes in this program list i need to print an ***** like line. TO indicate all the materials printed.
When 3nd program comes again i have to write Program Name: Program3, Then column heading MATNR, BERID below it and data of that program[1st] below them till all the 1st program's data finished. Whenever MATNR value changes in this program list i need to print an ***** like line. TO indicate all the materials printed.
Etc. Same process we need to follow.
The final out put should be as below:
PROGRAM NAME : PROGRAM1
MATNR, BERID
1000,MRP!
1000,MRP1
2000,MRP1
PROGRAM NAME : PROGRAM2
MATNR, BERID
1000,MRP!
1000,MRP1
2000,MRP1
PROGRAM NAME : PROGRAM3
MATNR, BERID
1000,MRP!
1000,MRP1
2000,MRP1
Like wise o/p need to be send to I_OBJTXT and to email.
<b>The logic i have written is as follows:</b>

Internal table logic required

Hi ,
I have two internal tables having with different structures . Finally I need to pass data to final internal table.
In runtime we have data in only one table. The final internal table should take either internal1, or internal table 2.
it_final_data[] = it_first_data[].
or
it_final_data[] = it_sec_data[].
i have to one generic include , it will understands the IT_final_data internal table only.
please help me.
regards,
Ajay

Hi Ajay,
     Build your final internal table with all the fields from first and second internal table. Use the below logic to move the data to the final internal table depending on the internal table data which you want to display.
IF not it_first_data[] is initial.
loop at it_first_data.
    move-corresponding it_frist_data to it_final_data.
    append it_final_data.
endloop.
else.
   loop at it_second_data.
    move-corresponding it_second_data to it_final_data.
    append it_final_data.
endloop.
endif.
Hope this works for you.

Internal Table Logic Needed

Hi all,
I have a requirement regarding data processing in a internal table,
internal table consists of filelds Vendor,Material and Scheduling Dates and Total Qty.
Here i need to fill the field Total Quantity, individual addition of quanties of that material for a particular vendor .
Let us consider intitially my internal table consists of data like this with these fields.
                  Vendor ,           Material ,            qty(individual),   Total qty   , Schedule dates
                   v1        ,           m1       ,                 10
                   v1        ,           m1        ,                10
                   v1       ,             m1       ,                  20
                   v1       ,              m2      ,                    5
                   v1       ,             m2        ,                 10
                   v2        ,            m2         ,                20
                  v2        ,             m2        ,                  15
                  v2        ,            m3         ,                  20
                  v2        ,            m3           ,                10
    Initiall the total qty field is empty i need to fill tht field for the last item for a particular material Like M1
for vendor v1 and total qty of m2 for vendor v1, total qty of m1 for v2, total qty of m2 for v2 and so on.
Requied output should be like this.
                 Vendor     ,          Material       ,    qty(individual)            Total qty   Schedule dates
                  v1         ,                m1         ,         10           ,               0
                   v1          ,              m1          ,        10           ,                 0
                   v1         ,                m1         ,         20          ,                40(101020)
                   v1        ,                 m2          ,         5           ,               0
                   v1          ,               m2           ,      10            ,              15(5+10)
                   v2          ,               m2          ,        20            ,             0
                   v2          ,               m2           ,       15             ,              35(20+15)
                  v2           ,              m3          ,        20              ,             0
                  v2            ,              m3           ,       10              ,           30(20+10)
Here i made one thing , i calculated the total qty of material for particular vendor.
Like
         Vendor                           Material                     Total Qty
                 v1        ,                        m1            ,             40
                 v1        ,                       m2              ,            15
                 v2         ,                     m2                ,           35
                 v2          ,                    m3                 ,           30
Finally i need the logic by using Control Events(At New   , At End of ) to adjust that total qty of a material for a particular vendor by Modifying the internal table.
i hope my problem is clear , pls let me know if any clarifications needed. and
code for the same .
Thannks in advance,
Niranjan.

Hi,
Solution is here.
sort itab by vendor material.
field-symbols: <itab> like line of itab.
loop at itab assigning <itab>.
on change of vendor.
clear flag.
endon.
add <itab>-quanity to lw_quantiy.
*--here pdate internal table end of each similar kind of record
at end of.
flag = 'x'.
<itab>-totalqty = lw_quantiy.
clear lw_quantiy
endat.
*--rest of record update zero by checking flag
if flag is initial.
<itab>-totalqty = 0.
endif.
endloop.
close this thread if you got solution.

Hi Praveen,
You have to SORT the internal table ITAB by a field of your requirement. Then DELETE adjacent entries in the internal table by comparing the field of interest.
SORT ITAB BY NUM1 NUM2.
DELETE ADJACENT DUPLICATES FROM ITAB COMPARING NUM1 NUM2.
After doing this you can perform the required actions on ITAB.
Hope this has cleared your doubt.

points will be rewarded for correct answer.

hi,
Actually i'm downloading the data from mara table to excel file i.e from mara -> internal table-> excel file.
In this i'm gettng all the values in excel file but i don't kno what those values exactly ment for , so i want the fields lable to be passed first.

Loop at itab into wa.
if wa-flag = 'E'.
c = c + 1.
endif.
Endloop.
Write:/ 'Total records', c.
OR
LOOP AT itab WHERE flag = 'E'.

   How to transfer the Header & its corresponding Item data
        to third Internal table
thanks and regards,

Hi Bala,
DATA : BEGIN OF IT_LIKP OCCURS 0, "1st internal table
       FIELD1,
       FIELD2,
       FIELD3, ETC....
       END OF IT_LIKP.
DATA : BEGIN OF IT_VBPA OCCURS 0, "2nd internal table
       FIELD1,
       FIELD2,
       FIELD3, ETC....
    END OF IT_VBPA.
DATA : BEGIN OF IT_FINAL OCCURS 0, "3rd internal table
       FIELD1,
       FIELD2,
       FIELD3, ETC....
END OF IT_FINAL.
SELECT STATEMENTS ON FIRST 2 INTERANL TABLES AND THEN PASS THE DATA IN THE FINAL INTERNAL TABLE IE IT_FINAL.
THEN WITH IT_FINAL TABLE DISPLAY THE DATA.
LOOP AT IT_LIKP.
    IT_FINAL-VBELN = IT_LIKP-VBELN.
    IT_FINAL-WADAT_IST = IT_LIKP-WADAT_IST.
    IT_FINAL-KUNNR = IT_LIKP-KUNNR.
    IT_FINAL-NAME1 = IT_LIKP-NAME1.
    IT_FINAL-VBELN_S = IT_LIKP-VBELV.
    IT_FINAL-ERDAT = IT_LIKP-ERDAT.
    READ TABLE IT_VBPA WITH KEY VBELN = IT_LIKP-VBELV BINARY
    SEARCH.
    IF SY-SUBRC = 0.
      IT_FINAL-KUNN2 = IT_VBPA-KUNNR.
      IT_FINAL-NAME2 = IT_VBPA-NAME1.
    ENDIF.
    APPEND IT_FINAL.
    CLEAR IT_FINAL.
ENDLOOP.

Question on internal table logic..

Gurus,
I have a internal table as follows:
it_tab:
ID---ACTION---CHANGE
A1-----X--
B2----
U
C1-----X--
U
C2-----X--
Without looping at the table, how can I find get the result that the internal table has 3 ids with ACTION ='X'
and 1 ID with ACTION = X and Change = U.
Regards,
Rajesh.

I agree with Rob, why not loop?
First thing without loop that comes to mind is
Using the Read statement 4 times with index 1,2,3 & 4.

DNP

Internal table logic

Hi,
I have a scenario that I am trying to work on:
I have three internal tables itab1 itab2 and itab3, all three internal tables have same fields in them but might be different values:
All the internal tables have three rows of data and in each row there are five fields VAL1 VAL2 VAL3 VAL4 VAL5.The requirement is I need to compare all these three tables as below:
Compare all the fields of itab1 with itab2, if they are same then skip and if not then compare each field of itab1 to itab3, if they are same then skip and if not replace the value of itab1 field (which is different with the one on itab3)with the itab3 field value.
can you please help me with this?

Hi Vijay,
I started writing the code as below:
loop at itab1 into wa_itab1.
READ TABLE itab2 INDEX sy-index into waA_itab2.
READ TABLE itab3 INDEX sy-index into wa_itab3.
if wa_itab1-val1 = wa_itab2-val1.
skip.
else.
if_wa_tab1-val1 = wa_itab3-val1.
skip.
else.
wa_tab1-val1 = wa_itab3-val1.
endif.
endif.
if wa_itab2-val1 = wa_itab2-val2.
skip.
else.
if_wa_tab2-val1 = wa_itab3-val2.
skip.
else.
wa_tab1-val2 = wa_itab3-val2.
endif.
endif.
if wa_itab1-val3 = wa_itab2-val3.
skip.
else.
if_wa_tab1-val3 = wa_itab3-val3.
skip.
else.
wa_tab1-val3 = wa_itab3-val3.
endif.
endif.
if wa_itab1-val4 = wa_itab2-val4.
skip.
else.
if_wa_tab1-va4l = wa_itab3-val4.
skip.
else.
wa_tab1-val4 = wa_itab3-val4.
endif.
endif.
ENDLOOP.
but I am not sure if whatever I have written is correct.
