Get One Column from an internal table without looping

Posted on Sep 15, 2006 at 02:16 PM 2k Views

Hi All,

I have a Huge Internal Table with several columns and would like to get Just two columns from it to another internal table that has just two columns.

Something like this:

Table A;
	
Fld1	Fld2	Fld3	Fld4
1	11	21	31
2	12	22	32
3	13	23	33
4	14	24	34
5	15	25	35
6	16	26	36

And the resulting second table after the move.

Table B;

Fld1	Fld2	
1	11	
2	12	
3	13	
4	14	
5	15	
6	16

But as the Table A is huge with about a 100,000 records; Looping through takes up a lot of resources. And

TableA[] = TableB[] doesn't work for me as the Flds have a different structure in the two tables.

Is there any other way to get around this.?

Thanks in advance..!

Jr

    Hi

    The answer is NO. Cant achieve that without looping at the huge table.

    But, looping on that internal table and populating the second table will not have any issues if records are more...

    I guess you have to loop it .there is no other way.

    Anyway, you must have already looped some other table when you have built the first table. Populate the second table as well in the same step.

      hi,

      i have tried it like this,

      data : begin of it_ekko occurs 0,
        ebeln type ebeln,
        bstyp type bstyp,
        bsart type bsart,
        statu type statu,
       end of it_ekko.
data : begin of t_ekko occurs 0,
        ebeln type ebeln,
       end of t_ekko.  

start-of-selection.
  SELECT EBELN
         BSTYP
         BSART
         STATU
    FROM EKKO
    INTO TABLE IT_EKKO
   WHERE EBELN IN S_EBELN.

   t_ekko[] = it_ekko[].

      it assign the ebeln to t_ekko.

      it is working fine. if you are having different field then how can you assign different fields.

      Regards,

      Richa

    I don't believe you can do it without looping the table

    Hi jr,

    1. It can be done.

    2. Provided the following simple things are fulfilled.

    a) Table A should have also have

    FIELD1, FIELD2 (of internal table B)

    As the FIRST TWO FIELDS (Starting from Left)

    3. Then

    tableb[] = tablea[]

    will work PERFECTLY FINE.

    4. To get a taste of it, just copy paste

    5.

    report abc.

    data : t001 like t001 occurs 0 with header line.

    data : begin of itab occurs 0,

    mandt like t001-mandt,

    bukrs like t001-bukrs,

    end of itab.

    *-------

    select * from t001

    into table t001.

    itab[] = t001[].

    break-point.

    regards,

    amit m.

      Hi

      Some guys are right and I was wrong.

      I tried this code and worked fine:

      DATA: BEGIN OF ITAB1 OCCURS 0,

      FIELD1(4) TYPE N,

      FIELD2(4) TYPE N,

      FIELD3(4) TYPE N,

      FIELD4(4) TYPE N,

      END OF ITAB1.

      DATA: BEGIN OF ITAB2 OCCURS 0,

      FIELD1(4) TYPE N,

      FIELD2(4) TYPE N,

      END OF ITAB2.

      DO 1000 TIMES.

      MOVE SY-INDEX TO ITAB1-FIELD1.

      ITAB1-FIELD2 = ITAB1-FIELD3 = ITAB1-FIELD4 = ITAB1-FIELD1.

      APPEND ITAB1.

      ENDDO.

      ITAB2[] = ITAB1[].

      LOOP AT ITAB2.

      WRITE: / ITAB2.

      ENDLOOP.

    Try out this code. Its working fine.

    Data : begin of it_vbak occurs 0,

    vbeln like vbak-vbeln,

    ernam like vbak-ernam,

    end of it_vbak.

    Data : begin of it_final occurs 0,

    vbeln like vbak-vbeln,

    end of it_final.

    select vbeln ernam from vbak into table it_vbak.

    it_final[] = it_vbak[].

    endloop.

      Hi Ravi,

      Yes i agree looping is a way but i want to know any other method apart from looping like some direct one line statements like ITAB1 IN ITAB2 etc.. which should give me the common values of both the internal table . and here both the internal table have same structure also

    Hi,

    If in both the internal tables if the common columns are placed leftmost of their structure you can directly use the body operator..THis will work fine..

    TABLEB[] = TABLEA[].

    Thanks,

    Naren
