Rows to Column Conversion in ABAP

Hello guys,
I wanted to create a report in which I need to convert rows in to column.
e.g.
I have a itab_col which contains my column header as follows.
itab_col-plant        itab_col-name
1000                     Plant A
2000                     Plant B
3000                     Plant C
I have a itab_data which contains my data as follows .
itab_data-date    itab_data-qty       itab_data-plant
01.06.2006           10                  1000
01.06.2006           20                  1000
01.06.2006           50                  2000
02.06.2006           20                  3000
I need to print the report as follows
Date       Plant A      Plant B      Plant C
01.06.2006     30           50           0
02.06.2006     0            0            20
Could you tell me how I can do it in abap.

Hi,
first create table with following attribute.
table_row_to_column
1. date
2. Plant A
3. Plant B
4. Plant C.
.............D E F ..number of plant possible.
Sum Up The data
01.06.2006 10 1000
01.06.2006 20 1000
01.06.2006 50 2000
02.06.2006 20 3000
01.06.2006 30 1000
01.06.2006 50 2000
02.06.2006 20 3000
to new data_table_sum_value
<b>for that u have to</b>
1) Sort the table date & plant.
2) sum up records for similar plant based on date
<b>Convert rows in to column.</b>
loop at data_table_sum_value.
case data_table_sum_value-plant.
    when 1000.
       table_row_to_column-plant_A = data_table_sum_value-qnty.
    when 2000.
       table_row_to_column-plant_B = data_table_sum_value-qnty.
    when 3000.
       table_row_to_column-plant_C = data_table_sum_value-qnty.
    when 4000.
       table_row_to_column-plant_D = data_table_sum_value-qnty.
    when 5000.
       table_row_to_column-plant_E = data_table_sum_value-qnty.
endcase.
   at end of date.
     append table_row_to_column.
   endat.
endloop.

Row to Column conversion

Hi,
i am having following table
SELECT* FROM Col_to_row;
output is:
A      B      C
X      Y      Z
1      2      3
i want to write query for below output, need to convert row into column for n number of rows for example i have taken only 3 rows:
A X 1
B Y 2
C Z 3

Three things to notice in this solution:
1) I am ordering by the original column name. You may want to order by something else.
2) When pivoting, you must indicate the name, number and datatype of the columns, so if there is a fourth line of input you have to add a column to the query.
3) This works on Oracle 11GR1 and above. Next time, be sure to indicate your Oracle version from the start.create table COL_TO_ROW(C1, C2, C3) as select
'A', 'B', 'C' from DUAL union all select
'X', 'Y', 'Z' from DUAL union all select
'1', '2', '3' from dual;
select * from (select rownum rn, a.* from COL_TO_ROW a)
UNPIVOT(VAL for COL in(C1, C2, C3))
PIVOT(max(VAL) for RN in (1,2,3))
order by col;
COL 1 2 3
C1 A X 1
C2 B Y 2
C3 C Z 3

Row to column conversion during excel download

Dear Experts,
I have an internal table with one column.
It has some entries say ten.
I want this ten rows of entries to be displayed in the excel sheet as a single row. It means each row entry of the internal table should fit in to each cell.
Is there any possibility with GUI_DOWNLOAD FM to do this?
If not, then how could i do that?
Please let me know its urgent.
Regards,
Shashi

Hi,
i m not aware of whether it can be done through FM 'GUI_DOWNLOAD' but i have one sugeestion.
You can first transpose your internal table and then download it.

Row to column conversion in large result set

I need to get the differnt levels of alerts for each user, with the total alert counts and counts for each type of alert.
SELECT COUNT(*) TOTAL,
        u.name,
        d.deptname,
        COUNT(CASE WHEN al.severity = 5 THEN 1 END) INDETERMINATE,
        COUNT(CASE WHEN al.severity = 4 THEN 1 END) WARNING,
        COUNT(CASE WHEN al.severity = 3 THEN 1 END) MINOR,
        COUNT(CASE WHEN al.severity = 2 THEN 1 END) MAJOR,
        COUNT(CASE WHEN al.severity = 1 THEN 1 END) CRITICAL
FROM alerts al, user u, dept d
WHERE al.userid = u.userid
AND u.deptid = d.deptid
AND al.time = sysdate - 4/24
AND al.time <= sysdate
GROUP BY u.name, d.deptname This might be inefficient especially when the amount of data is huge and potentially you could be looking at millions of rows in a given interval. So I was thinking of grouping by severity, which would eliminate the CASE statements, but then the problem on group by is that I get it as a rows instead of columns.
Would anyone have a suggestion as to do it effeciently especially one that has millions of rows? Thanks.

I guess eventually we are probably going to move towards that, but using a staright forward query is the immediate solution and any help on that would be great. Thanks.

Reg:Row to column conversion

Hi All,
I will give string three string values in a single variable like CNTNS_VAL_STR = test,value,small
but i need result like
test
value
small
Please help to reslove the one
thanks,

Your requirement isn't very clear anymore.
Please post a small testcase, like I did below, assuming you're looking for a way to query column values based on an input string:
SQL> create table t as
2 select 1 rn,'A' descr from dual union
3 select 2,'B' from dual union
4 select 3,'C' from dual union
5 select 4,'Q' from dual union
6 select 5,'X' from dual;
Table created.
SQL> select * from t;
        RN D
         1 A
         2 B
         3 C
         4 Q
         5 X
5 rows selected.
SQL> create or replace function str2tbl( p_str in varchar2, p_delim in varchar2 default ',' )
2 return sys.odcivarchar2list
3 pipelined
4 as
5      l_str long default p_str || p_delim;
6      l_n   number;
7 begin
8      loop
9          l_n := instr( l_str, p_delim );
10          exit when (nvl(l_n,0) = 0);
11          pipe row( ltrim(rtrim(substr(l_str,1,l_n-1))) );
12          l_str := substr( l_str, l_n+1 );
13      end loop;
14      return;
15 end;
16 /
Function created.
SQL> select *
2 from   t
3 where descr in ( select column_value
4                   from   table(str2tbl('A,B,C'))
5                 );
        RN D
         1 A
         2 B
         3 C
3 rows selected.
So, I more or less 'joined' a table to a pipelined function (no cursor needed) based on an input string.
If you search for 'str2tbl' on http://asktom.oracle.com then you'll find many more examples.

Hi,
I know this question has been asked couple of times but I could not understand from them hence posting my query here.
I have a table named XYX

Row to Column Conversion Question

Hi All,
Could you please help on this sql query statement:
SELECT BENEFIT FROM TEST_T ;
BENEFIT
QO,1G,1U,1W
Out Put Needed like this
BENEFIT
QO
1G
1U
1W
Thanks,

Hi,
As I said, it depends on your data, your requirements and your version.
REGEXP_COUNT was new in Oracle 11.1. Since you're using an earlier version, you can see how many comma-delimited sub-strings you have by seeing how much shorter the string gets if you remove all the commas:
1 + LENGTH (benefit)
- LENGTH (REPLACE (benefit, ','))
This assumes you don't have data with mutiple consecutive commas such as 'AB,,,,CD', but it might not cause any terrible results even if you do.
The way I used CONNECT BY won't work in Oracle 10, either.
Now I know everything I need to know about your Oracle version, but I don't know anything about your data or your requirements. Do you want me to spend my time writing solutions that assume things about your data and your requirments, so you can spend your time trying them only to see that they don't do what you need?
Explain what your data is like. Do you have a fixed number of comma-delimited parts (e.g., always 4 parts). If not, do you have an upper bound (e.g., never more than 10 parts)? Can you have multiple consecutive commas?
Explain what you need to get from that data. Will you always be splitting one string into parts, as in the example you posted, or will you need to split multiple stings in the same query? Will the correct results ever contain NULL?
Post a little sample data (CREATE TABLE and INSERT statements), showing all special cases you need to handle. Post the results you want from that data.
See the forum FAQ: https://forums.oracle.com/message/9362002

      line(150),
     end of itab1.
Sort itab by col1 col2. ( Here itab is your table )
loop at itab.
at new col2.
write: / itab-col1,
             itab-col2.
concatenate itab-col1
                    itab-col2
           into itab1.
endat.
write itab-col3.
concatenate itab1
                    itab-col3
    into itab1.
at end.
append itab1.
clear itab1.
endat.
endloop.
loop at itab1.
write / itab1.
endloop.

Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 1, column 3 (NumberOfMultipleMatches).

Thanks in advance
Vikram

To load that file with BULK INSERT, use this format file:
9.0
4
1 SQLCHAR 0 0 "\"" 0 "" ""
2 SQLCHAR 0 0 "\",\"" 1 col1 Latin1_General_CI_AS
3 SQLCHAR 0 0 "\",\"" 2 col2 Latin1_General_CI_AS
4 SQLCHAR 0 0 "\"\r\n" 3 col3 Latin1_General_CI_AS
Note that the format file defines four fields while the fileonly seems to have three. The format file defines an empty field before the first quote.
Or, since you already have a .NET program, use a stored procedure with table-valued parameter instead. I have an example of how to do this here:

Converting key figures from rows to column using DSO and start routine

Hi SDNer:
I need some help to convert key figures from rows to column.
The source is DSO 1 and I am thinking about writing ABAP in the start routine to do the conversion. The target is DSO2.
Below is the more detail information with example. Basically, for each record in DSO 1 I need to create 3 records (because there are 3 KF's) and output to DSO2.
I would really appreciate some help on this.Thank you.
Tony
DSO 1 data format (SOURCE)
Period   ID   KF1 KF2 KF3
200702 100 300 200   750

200702 100 300 KF1
200702 100 200 KF2
200702 100 750 KF3

This is the code in BI 7.0.
u need to put a field "Label" in DSO1. u dont need to populate this in DSO1 but it helps the code to populate the field in DSO2.
DATA: wa_result TYPE _ty_s_sc_1,
t_result TYPE STANDARD TABLE OF _ty_s_sc_1.
DATA:counter(2) TYPE n.

wa_result- ID = wa_result-ID.
if counter = 0.
wa_result- KF1 = wa_result-KF1.
wa_result- Label = 'KF1'.
elseif counter = 1.
wa_result- KF1 = wa_result-KF2.
wa_result- Label = 'KF2'.
else.
wa_result- KF1 = wa_result-KF3.
wa_result- Label = 'KF3'.
endif.
APPEND wa_result TO t_result.
counter = counter+1.
endwhile.
endloop.
CLEAR: SOURCE_PACKAGE,wa_result.

Keeping row and column headers while scrolling inside a Web Dynpro table

Hi,
I have to display a 2x2 matrix with storage location names on the x-axis (i.e. as Column Headers) and material names on the y-axis (i.e. row headers). The table data represents the quantities of a particular material in a particular storage location.
I am using dynamic UI generation to create this table. It can contain as many as 150 columns and almost as many rows. I dont want a page level scrollbar, and hence, have placed my table inside a scroll container UI element with a fixed height and width.
I need a way to let the users use the scrollbars inside the scroll container, but still let them see the row and column headers. Is there a way that I can do this in Dynpro for Java?
Thanks,
Navneet Nair.

Hi Kenn,
You are probably better off posting this request in this forum User Interface Development in ABAP as you are more likely to get a response.

Neil.

Web dynpro screen with multiple rows with columns that can be edited

Web dynpro screen with multiple rows with columns that can be edited individually:
Hi
I am busy creating a screen in web dynpro for ABAP which we would like to make available via Portal ESS (Portal 7).
I need to add 'n type of table (or almost something like Excel) or something in which someone can type a few paycode numbers (there should be lets say 10 blank rows in which info can be typed in and if I click on a button or so, more rows must be added if necessary. Then in the other colums stuff like amounts must be entered which one should also be able to edit then and there.
Can anyone assist in what I can use for this? There does not seem to be some existing element that I can use.
Help will be appreciated.
Regards
Debbie

Hi Debbie,
Whiel Creating table you need to be care full that use chose INPUT FIELD as the CELL EDITOR. Just guessing that if ur table is not editable u might have choosen TextView as default cell editor type.

easy way is to first add UI ELEMENT TABLE to your VIEW, then right click over it & select create binding from context. After you have a pop up where you can select what columns you want what should be its cell editor etc.

Converting from rows to columns

Converting Rows to Columns
We have one business requirment where they want to convert rows to columns. The data we are talking about is 2-3 TB of data. Data looks something in this format.
Table Structure
Date_1 Unit_Number Data_ID Data_Value
2013-01-02 00:00:00 100013 123 671
2013-01-02 00:00:00 100014 131 771
2013-01-02 00:00:00 100015 281 812
2013-01-02 00:00:00 100016 712 979
2013-01-02 00:00:00 100017 715 719
Pivoted table
Date_1 RY XY HJ KD IK GH HH KK TK RT ...
2013-01-02 00:00:00 671 771 812 979 719 979 719 980 799 79
2013-01-02 00:10:00 671 771 812 979 719 979 719 980 799 79
and so on
We are pivoting this data using query and creating view using query something like below
select a.date_1 date_1 a.unit_number system_number,
max(CASE WHEN a.data_id= 123 then a.DATA_Value END) RY,
max(CASE WHEN a.data_id= 281 then a.DATA_Value END) XY,
max(CASE WHEN a.data_id=712 then a.DATA_Value END) HJ,
max(CASE WHEN a.data_id=715 then a.DATA_Value END) KD,
max(CASE WHEN a.data_id=666 then a.DATA_Value END) IK,
max(CASE WHEN a.data_id=231 then a.DATA_Value END) GH,
max(CASE WHEN a.data_id=881 then a.DATA_Value END) HH,
max(CASE WHEN a.data_id=734 then a.DATA_Value END) KK,
max(CASE WHEN a.data_id=734 then a.DATA_Value END) TK,
max(CASE WHEN a.data_id=724 then a.DATA_Value END) TK,
from FROM table_name group by 1,2
We also tried pivot clause but still no major improvement in performance.
There are about 40 such rows that we are trying to convert into columns. We created indexes, Primary, Secondary and referencial ones to tune this overall query. Also added paritions, We find this conversion works fine for smaller query, however for larger set of data we get high CPU and IO and also often runs into spool error. The data set we are runing on this query are about 3-4 TB. There is another table where we have about 100 rows which we need to convert into one row and again size goes to 4-5 TB
Questions I have
1) Is there better way to convert columns to Rows?
2) What options can be use to reduce CPU, IO and Spool error?
3) Does Orage 11g datawarehouse any feature which will hellp us here
4) Any other appproach or design suggested here that will help us?
This design is pushed by our business due to flexibility this design offers and we are runing into performance and we are trying to make this work without impacting CPU, Spool and IO
Any suggestions would help us here, thanks for reading this

Hi,
Here's one way to do that:
WITH     got_times     AS
     SELECT     MAX ( CASE
               WHEN msg_line = 'LONGITUDINAL REFRESH HAS BEGUN'
               THEN msg_datetime
              )          AS start_time
     ,     MAX ( CASE
               WHEN msg_line = 'LONGITUDINAL REFRESH HAS COMPLETED'
               THEN msg_datetime
              )          AS end_time
     FROM     xxwv.xxwv_hsum_info_reports
SELECT     start_time
,     end_time
,     (end_time - start_time) * 24 * 60     AS duration_minutes
FROM     got_times
;When you run the two different (but very similar) to get the two times, you have two different WHERE clauses. You can combine those two similar queries into one, but whatever WHERE clause you have will apply to the whole query. Whenever you wish you could apply a WHERE clause just to one column, think of CASE instead.

Rows and Columns

Dear all,
Could u plz tell me how to create rows and columns dynamically at runtime?
I got 3 columns and multiple rows.How do i go about it?
Is there ne FM to do this?

Can you create an internal table dynamically? (at run time)
Yes , you can create a Dynamic Internal table .Just chek out this program .
type-pools : abap.
field-symbols: <dyn_table> type standard table,
               <dyn_wa>,
               <dyn_field>.
data: dy_table type ref to data,
      dy_line type ref to data,
      xfc type lvc_s_fcat,
      ifc type lvc_t_fcat.
selection-screen begin of block b1 with frame.
parameters: p_table(30) type c default 'T001'.
selection-screen end of block b1.
start-of-selection.
    perform get_structure.
perform create_dynamic_itab.      *********Creates a dyanamic internal table*********
perform get_data.
perform write_out.
form get_structure.
data : idetails type abap_compdescr_tab,
       xdetails type abap_compdescr.
data : ref_table_des type ref to cl_abap_structdescr.
Get the structure of the table.
ref_table_des ?=
      cl_abap_typedescr=>describe_by_name( p_table ).
idetails[] = ref_table_des->components[].
    loop at idetails into xdetails.
    clear xfc.
    xfc-fieldname = xdetails-name .
    xfc-datatype = xdetails-type_kind.
    xfc-inttype = xdetails-type_kind.
    xfc-intlen = xdetails-length.
    xfc-decimals = xdetails-decimals.
    append xfc to ifc.
endloop.
endform.
form create_dynamic_itab.
Create dynamic internal table and assign to FS
call method cl_alv_table_create=>create_dynamic_table
               exporting
                  it_fieldcatalog = ifc
               importing
                  ep_table        = dy_table.
    assign dy_table->* to <dyn_table>.
Create dynamic work area and assign to FS
create data dy_line like line of <dyn_table>.
assign dy_line->* to <dyn_wa>.
endform.
form get_data.
Select Data from table.
select * into table <dyn_table>
             from (p_table).
endform.
   Write out data from table.
loop at <dyn_table> into <dyn_wa>.
    do.
      assign component sy-index
         of structure <dyn_wa> to <dyn_field>.
      if sy-subrc <> 0.
        exit.
      endif.
      if sy-index = 1.
        write:/ <dyn_field>.
      else.
        write: <dyn_field>.
      endif.
    enddo.
endloop.
