Fetching data from one internal table and populating into other table

hi
i am working on a report program.
here,i have my data in a internal table(having only one field) i.e. only one column in the table.
now i want to populate this data into other internal internal table that has 13fields i.e. 13 columns.
so could anyone let me know how can i work on this.
i am looping the internal table with one field into a work area from there i am not able to proceed ahead.
thanks in advance

hi
i would like to clear one point here i.e. my internal table into which i want to populate data is a dynamic internal table....so i cant give the fieldnames here..
here i am pasting the code..so that u may get some idea...
"generating dynamic internal table :
ref_descr ?= cl_abap_typedescr=>describe_by_data( it_itab ).
it_details[] = ref_descr->components[].
loop at it_details into wa_comp.
cnt = cnt + 1.
wa_fcat-col_pos = cnt.
wa_fcat-fieldname = wa_comp-name.
append wa_fcat to t_fcat.
endloop.
CALL METHOD CL_ALV_TABLE_CREATE=>CREATE_DYNAMIC_TABLE
EXPORTING
    I_STYLE_TABLE             =
    IT_FIELDCATALOG           = t_fcat
    I_LENGTH_IN_BYTE          =
IMPORTING
   EP_TABLE                  = lo_table
    E_STYLE_FNAME             =
EXCEPTIONS
    GENERATE_SUBPOOL_DIR_FULL = 1
    others                    = 2
so lo_table is my dynamic internal table.
ASSIGN lo_table->* TO <f_tab>.
using the GUI_UPLOAD i have uploaded the data file(separated by semicolon) from presentation server and its in the table itab.
with the following logic i am capturing the data in between the semicolon's.
LOOP AT itab INTO wa_itab.
find all occurrences of c_semicolon in wsg_string results result_tab.
loop at result_tab into wa_reslt.
if sy-tabix = 1.
str1 = wsg_string+0(wa_reslt-offset).
wa_prev_offset = wa_reslt-offset.
wa_prev_offset = wa_prev_offset + 1.
clear str1.
else.
   count = wa_reslt-offset - wa_prev_offset.
   count = count.
str2 = wsg_string+wa_prev_offset(count).
clear str2.
wa_prev_offset = wa_reslt-offset.
wa_prev_offset = wa_prev_offset + 1.
enddo.
endif.
endloop.
data is there in the fields str1 and str2.now i want to populate this data into dynamic internal table row-wise.
could anyone suggest me how can i do this

How do i transfer data from one internal tabe to another.

Hi All,
         How do i transfer data from one internal tabe to another.
         Can i do it ebven if he tables are different in structure.
Please Advice.
Thanks in advance.

Hi Saket Tiwari,
I hope the earlier post by kashyap is good enough an answer. anywas in addition to it let me give a detailed
explanation of how you can populate an internal table.
1) Append data line by line.
     Syntax : APPEND [<wa> TO / INITIAL LINE TO] <itab>.
this appends new line to internal table <itab>.
2) Using COLLECT statement.
             COLLECT is another form of statement used for populating the internal tables. Generally COLLECT is used while inserting lines into an internal table with unique standard key. The syntax for COLLECT statement is as shown
     Syntax : COLLECT [<wa> INTO] <itab>.
3) Using INSERT statement
     Syntax INSERT [<wa> INTO / INITIAL LINE INTO] <itab> [index <idx>].
INSERT statement adds a line/work area to the internal table. You can specify the position at which the new line is to be added by using the INDEX clause with the INSERT statement.
Now coming to your request..
To append part or all of an internal table
     Syntax
              APPEND LINES OF <itab1> [FROM <n1>] [TO <n2>] TO <itab2>.
*     Note:
Without the FROM and TO options, this statement appends the entire table <itab1> to <itab2>.*
b) To insert part or all of an internal table into another internal table
     Syntax
          INSERT LINES OF <itab1> [FROM <n1>] [TO <n2>]
          INTO <itab2> [INDEX <idx>].
c) Using Move statement.
To copy entire contents of one table into another in one execution
     Syntax MOVE <itab1> To <itab2>.
               OR
          <itab1> = <itab2>.
but u hav to be careful because he contents of itab2 will eb overwritten on the execution of this statement.
These copy the contents of ITAB1 to ITAB2. Incase of internal tables with header line we have to use [] inorder to distinguish from work area. So, to copy contents of internal tables with header line the syntax becomes,
ITAB1[] = ITAB2[].
Coming to the letter part of your question, Yes, we can copy values between tables having different structures.
for this we use
                            MOVE-CORRESPONDING <itab1> TO <itab2>
    this executes the statement for their header lines. Searches for the sub-fields which occur both in itab1 and itab2 and then generates, for all relevant field pairs which correspond to the
        sub-fields ni , statements of the form MOVE itab1-ni TO itab2-ni. The other fields remain unchanged.
I hope the information provided has been of your help.
Reward if useful.

How to pass data from one internal session to another internal session

hi all sap experts ,
How to pass data from one internal session to another internal session and from oneExternal session to another external session.
Except : Import and Export parameters and SPA/GPA parameters.
Tell me the otherWay to pass data ..
Plz
Thanks in advance

hi,
abap memory management u will understand about this concept.
the import /export parameter will help u that passing data between two internal sessions by using abap memory.
for syntax
Passing Data Between Programs
There are two ways of passing data to a called program:
Passing Data Using Internal Memory Areas
There are two cross-program memory areas to which ABAP programs have access (refer to the diagram in Memory Structures of an ABAP Program) that you can use to pass data between programs.
SAP Memory
SAP memory is a memory area to which all main sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters can be set either for a particular user or for a particular program using the SET PARAMETER statement. Other ABAP programs can then retrieve the set parameters using the GET PARAMETER statement. The most frequent use of SPA/GPA parameters is to fill input fields on screens (see below).
ABAP Memory
ABAP memory is a memory area that all ABAP programs within the same internal session can access using the EXPORT and IMPORT statements. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse. For further information, refer to Data Clusters in ABAP Memory.
Filling Input Fields on an Initial Screen
Most programs that you call from other programs have their own initial screen that the user must fill with values. For an executable program, this is normally the selection screen. The SUBMIT statement has a series of additions that you can use to fill the input fields of the called program:
Filling the Selection Screen of a Called Program
You cannot fill the input fields of a screen using additions in the calling statement. Instead, you can use SPA/GPA parameters. For further information, refer to Filling an Initial Screen Using SPA/GPA Parameters.

How to pass data from one internal session to another

Hi SAP Experts,
How to pass data from one internal session to another and from One external session to another external session. I used import and export parmeter and SPA/GPA parameters. What is the other way to pass data?

Memory Structures of an ABAP Program
In the Overview of the R/3 Basis System you have seen that each user can open up to six R/3 windows in a single SAPgui session. Each of these windows corresponds to a session on the application server with its own area of shared memory.
The first application program that you start in a session opens an internal session within the main session. The internal session has a memory area that contains the ABAP program and its associated data. When the program calls external routines (methods, subroutines or function modules) their main program and working data are also loaded into the memory area of the internal session.
Only one internal session is ever active. If the active application program calls a further application program, the system opens another internal session. Here, there are two possible cases: If the second program does not return control to the calling program when it has finished running, the called program replaces the calling program in the internal session. The contents of the memory of the calling program are deleted. If the second program does return control to the calling program when it has finished running, the session of the called program is not deleted. Instead, it becomes inactive, and its memory contents are placed on a stack.
The memory area of each session contains an area called ABAP memory. ABAP memory is available to all internal sessions. ABAP programs can use the EXPORT and IMPORT statements to access it. Data within this area remains intact during a whole sequence of program calls. To pass data to a program which you are calling, the data needs to be placed in ABAP memory before the call is made. The internal session of the called program then replaces that of the calling program. The program called can then read from the ABAP memory. If control is then returned to the program which made the initial call, the same process operates in reverse.
All ABAP programs can also access the SAP memory. This is a memory area to which all sessions within a SAPgui have access. You can use SAP memory either to pass data from one program to another within a session, or to pass data from one session to another. Application programs that use SAP memory must do so using SPA/GPA parameters (also known as SET/GET parameters). These parameters are often used to preassign values to input fields. You can set them individually for users, or globally according to the flow of an application program. SAP memory is the only connection between the different sessions within a SAPgui.
The following diagram shows how an application program accesses the different areas within shared memory:
In the diagram, an ABAP program is active in the second internal session of the first main session. It can access the memory of its own internal session, ABAP memory and SAP memory. The program in the first internal session has called the program which is currently active, and its own data is currently inactive on the stack. If the program currently active calls another program but will itself carry on once that program has finished running, the new program will be activated in a third internal session.
Data Clusters in ABAP Memory
You can store data clusters in ABAP memory. ABAP memory is a memory area within the internal session (roll area) of an ABAP program and any other program called from it using CALL TRANSACTION or SUBMIT.
ABAP memory is independent of the ABAP program or program module from which it was generated. In other words, an object saved in ABAP memory can be read from any other ABAP program in the same call chain. ABAP memory is not the same as the cross-transaction global SAP memory. For further information, refer to Passing Data Between Programs.
This allows you to pass data from one module to another over several levels of the program hierarchy. For example, you can pass data
From an executable program (report) to another executable program called using SUBMIT.
From a transaction to an executable program (report).
Between dialog modules.
From a program to a function module.
and so on.
The contents of the memory are released when you leave the transaction.
To save data objects in ABAP memory, use the statement EXPORT TO MEMORY.
Saving Data Objects in Memory
To read data objects from memory, use the statement IMPORT FROM MEMORY.
Reading Data Objects from Memory
To delete data clusters from memory, use the statement FREE MEMORY.
Deleting Data Clusters from Memory

How to read LONG RAW data from one table and insert into another table

Hello EVERYBODY
I have a table called sound with the following attributes. in the music attribute i have stored some messages in the different language like hindi, english etc. i want to concatinate all hindi messages and store in the another table with only one attribute of type LONG RAW.and this attribute is attached with the sound item.
when i click the play button of sound item the all the messages recorded in hindi will play one by one automatically. for that i'm doing the following.
i have written the following when button pressed trigger which will concatinate all the messages of any selected language from the sound table, and store in another table called temp.
and then sound will be played from the temp table.
declare
     tmp sound.music%type;
     temp1 sound.music%type;
     item_id ITEM;
cursor c1
is select music
from sound
where lang=:LIST10;
begin
     open c1;
     loop

          temp1:=temp1||tmp;
          exit when c1%notfound;
     end loop;
CLOSE C1;
insert into temp values(temp1);
item_id:=Find_Item('Music');
go_item('music');
play_sound(item_id);

You can achieve this in many different ways, one is
1. Create another VO based on the EO which is based on the dest table.
2. At save, copy the contents of the source VO into the dest VO (see copy routine in dev guide).
3. commiting the transaction will push the data into the dest table on which the dest VO is based.
I understand that if we attach VO object instance to region/page, we only can pull and put data in to only one table.
if by table you mean a DB table, then no, you can have a VO based on multiple EOs which will do DMLs accordingly.Thanks

How to scan data from one internal table to another

Hi All,
let me know how to scan all from one internal table to another internal table. Pls provide me the syntax and code.
i am very thankful to you all in advance.
Thanks & Regards,
Nagarjuna.

if u want to copy data from itab1 to itab2 then use
itab2[] = itab1[].
if u want to compare whether both itab1 and itab2 are same or not,use
if itab1[] = itab2[].
*--same
else.
*--not same
endif.
if u want to compare itabs based on primary key....
loop at itab1.
read table itab2 with key f1 = itab1-f1.
if sy-subrc <> 0.
*--not same....
endif.
endloop.
if u want to copy only few lines(say from 1 to 3) of itab1 to itab2 then use...
append lines of itab1 from 1 to 3 to itab2.
if internal tables don't have same structure,
say only fields f1 and f2 are common,then
loop at itab1.
itab2-f1 = itab1-f1.
itab2-f2 = itab1-f2.
append itab2.
clear itab2.
endloop.
if there are many common fields then...
loop at itab1.
move-corresponding itab1 to itab2.
append itab2.
clear itab2.
endloop.

How can I Move data from one column to another in my access table?

I have two columns, one that stores current month’s data and one that stores last month’s data. Every month data from column 2 (this month’s data) needs to be moved to column 1 that holds last month’s data. I then null out column 2 so I can accumulates this month’s data.
I understand how to drop a column or add a column, how do I transfer data from one column to another.
Here is my trial code:
<cfquery name="qQueryChangeColumnName" datasource="#dsn#">
ALTER TABLE leaderboard
UPDATE leaderboard SET points2 = points3
</cfquery>
Unfortunately, I get the following error:
Error Executing Database Query.
[Macromedia][SequeLink JDBC Driver][ODBC Socket][Microsoft][ODBC Microsoft Access Driver] Syntax error in ALTER TABLE statement.
How can I transfer my data with the alter table method?

I looked up the Access SQL reference (which is probably a
good place to start when having issues with Access SQL), and
it suggests you probably need a WHERE clause in there.
I agree the documentation is a good place to start. But you should not need a WHERE clause here.
Too few parameters. Expected 1.
If you run the SQL directly in Access, what are the results? At the very least, it should provide a more informative error message..

Read data from E$ table and insert into staging table

Hi all,
I am a new to ODI. I want your help in understanding how to read data from an "E$" table and insert into a staging table.
Scenario:
Two columns in a flat file, employee id and employee name, needs to be loaded into a datastore EMP+. A check constraint is added to allow data with employee names in upper case only to be loaded into the datastore. Check control is set to flow and static. Right click on the datastore, select control and then check. The rows that have violated the check constraint are kept in E$_EMP+ table.
Problem:
Issue is that I want to read the data from the E$_EMP+ table and transform the employee name into uppercase and move the corrected data from E$_EMP+ into EMP+. Please advise me on how to automatically handle "soft" exceptions in ODI.
Thank you

Hi Himanshu,
I have tried the approach you suggested already. That works. However, the scenario I described was very basic. Based on the error logged into the E$_EMP table, I will have to design the interface to apply more business logic before the data is actually merged into the target table.
Before the business logic is applied, I need to read each row from the E$EMP table first and I do not know how to read from E$EMP table.

Fetching data from one BI server to another

Hi All,
We have BCS environment on top of BI. We have a request from Client to refresh the BCS data in our quality box (copy of BCS production data). Data wasn't refreshed to our Quality system regularly from SAP Quality and hence we thought of complete BI Production copy to our Quality box.
Since the above strategy is time consuming,we have been contemplating on other options and have stumbled upon SAP blog http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/21489. [original link is broken] [original link is broken] [original link is broken]
The blog talks about pulling data from one BI server to another. As BCS is such a fragile environment, wanted to take an opinion on whether you all see any concerns with the approach.
Regards,
Vivek Das Gupta

Hi,
W have done the system copy from production to QA system and only faced authorization issues and also we follwed the same blog and as mentioned in the blog dont forget below points before going ahead for the system copy.
switch the source Real Time Infocube (in MBP) if you want to copy all latest productive data, that is to say including those which were contained in the open request.
For data consistency reasons and to avoid any risk of error, the loading process is executed in Full.
If you planning to copy only a part of the source data records, set filters in the infopackages.
Hope it going help you
Thanks

How to extract data from multiple flat files to load into corresponding tables in SQL Server 2008 R2 ?

Hi,
          I have to implement the following scenario in SSIS but don't know how to do since I never worked with SSIS before. Please help me.
          I have 20 different text files in a single folder and 20 different tables corresponding to each text file in SQL Server 2008 R2 Database. I need to extract the data from each text file and
load the data into corresponding table in Sql Server Database. Please guide me in how many ways I can do this and which is the best way to implement this job. Actually I have to automate this job. Few files are in same format(with same column names
and datatypes) where others are not.
1. Do I need to create 20 different projects ?
               or
    Can I implement this in only one project by having 20 packages?
             or
    Can I do this in one project with only one package?
Thanks in advance.

As I said I don't know how to use object data type, I just given a shot as below. I know the following code has errors can you please correct it for me.

Fetch data from one table and insert into two tables in desired format

I have similar to the following data in a table and it is not normalized. The groupID is being used to group two records of similar nature.
DECLARE @OldDoc TABLE (oldDocID INT, groupID INT, deptID INT)
INSERT INTO @OldDoc (oldDocID, groupID) VALUES (1, NULL, 111),(2,NULL,111),(3,1,111),(4,NULL,333),(5,1,222),(6,NULL,333),(7,2,222),(8,2,333),(9,NULL,111),(10,3,222),(11,NULL,333),(12,3,444)
I need to process the data from the above table (@OldDoc) and write into two new tables (@NewDoc and @NewDocGroup) as follows.
oldDocID should be stored as newDocID when inserting to @NewDoc table. Only records with groupID NULL and one record (first one) per group should be considered (For example, oldDocID 5 is not considered as 3 and 5 belong to the same groupID 1) for insertion.
DECLARE @NewDoc TABLE (newDocID INT)
INSERT INTO @NewDoc (newDocID) VALUES (1),(2),(3),(4),(6),(7),(9),(10),(11)
All records from @OldDoc should be considered for insertion into @NewDocGroup table. OldDocID is inserted as NewDocID and deptID is as-is. Instead of groupID, the ID of the first record in the
group should be considered as parentNewDocID (For example, 3 is considered as parentNewDocID for newDocID 5 as 3 and 5 belong to the same groupID in @OldDoc table) for the newDocID.
DECLARE @NewDocGroup (newDocID INT, parentNewDocID INT, deptID INT)
INSERT INTO @NewDocGroup (newDocID, parentNewDocID, deptID) VALUES (1,1,111),(2,2,111),(3,3,111),(4,4,333),(5,3,222),(6,6,333),(7,7,222),(8,7,333),(9,9,111),(10,10,222),(11,11,333),(12,10,444)
How do I accomplish the above using SQL ? Thanks for the help.

Rows are not records. Tables have to have a key by definition. You do not do math with identifiers, so they should not be numeric. Let's ignore that error for now. In short, you are posting garbage. If you had followed Forum Netiquette, would you have posted
this?
CREATE TABLE Old_Documents

Just like punch cards and mag tape data processing! Being old and being new are a status, not another kind of entity. But that is how mag tapes work. And you even use the verb "fetch" from tape files. This design flaw is called attribute splitting.

Think about your punch card mindset. Why did you physically materialize that redundant New_Documents table? Let me answer that: this is how you work with punch cards! In SQL we use a VIEW:
CREATE VIEW New_Documents (new_doc_id)

FROM Old_Documents;
>> All records [sic] from Old_Documents should be considered for insertion into New_Documents_Groups table. The old_doc_id is inserted as new_doc_id and dept_nbr is as-is. Instead of group_id, the ID [sic: which identifier??] of the first [sic: tables

Why not use 5 as the parent? My guess is that you are trying to form equivalence classes. See:

How to get the data from one table and insert into another table

Moving data from one internal table to another

Hi,
I have one internal table populated with a list of material codes and another with all the material numbers.
ITAB1: MCODE KSCHL KNUMH MATNR
ITAB2: MCODE MATNR
The matnr field in itab1 is blank initially. It needs to be populated with all the material numbers from itab2. How can I achieve this?
Thanks,
ap

Hi
Lets say that there is only one record in itab1 and for that there is correspondingly 10 records in itab2.
that means that the one record in itab1 should be changed to the first material number in itab2 and there should be nine more records created in itab1 according to the values in itab2.
Hope this is what you mean.
If this is the logic then the following code should work
then lets have a third internal table the same type as itab1
Loop at itab1 into wa_itab1
*readt table itab2 into wa_itab2 with key mcode = wa_itab1-mcode.
*IF sy-subrc eq 0.
loop at itab2 into wa_itab2 where mcode = wa_itab1-mcode.
wa_itab1-matnr = wa_itab2-matnr
append wa_itab1 to itab3.
endloop.
*ENDIF.
*modify itab1 from wa_itab1.
endloop.
itab3 will contain all the values that you require

Hi Naval,
Declare an internal table of type table parameter structure and pass it the table parameters of the Function module.
Check the code for this function module.
DATA IT_MARA LIKE MARA OCCURS 0 WITH HEADER LINE.
SELECT * FROM MARA UP TO 10 ROWS INTO TABLE IT_MARA.
CALL FUNCTION 'GUI_DOWNLOAD'
    EXPORTING
      FILENAME                = 'C:\TEST.TXT'.      FILETYPE                = 'ASC'
      WRITE_FIELD_SEPARATOR   = 'X'
<b>    TABLES
      DATA_TAB                = IT_MARA</b>
    EXCEPTIONS
      FILE_WRITE_ERROR        = 1
      NO_BATCH                = 2
      GUI_REFUSE_FILETRANSFER = 3
      INVALID_TYPE            = 4
      NO_AUTHORITY            = 5
      UNKNOWN_ERROR           = 6
      HEADER_NOT_ALLOWED      = 7
      SEPARATOR_NOT_ALLOWED   = 8
      FILESIZE_NOT_ALLOWED    = 9
      HEADER_TOO_LONG         = 10
      DP_ERROR_CREATE         = 11
      DP_ERROR_SEND           = 12
      DP_ERROR_WRITE          = 13
      UNKNOWN_DP_ERROR        = 14
      ACCESS_DENIED           = 15
      DP_OUT_OF_MEMORY        = 16
      DISK_FULL               = 17
      DP_TIMEOUT              = 18
      FILE_NOT_FOUND          = 19
      DATAPROVIDER_EXCEPTION = 20
      CONTROL_FLUSH_ERROR     = 21

Transferring data from one internal table to another

Hi,
I have two internal tables it_acct and it_acct1 as below.
data: begin of it_acct occurs 0,
      belnr like bkpf-belnr,
      bldat like bkpf-bldat,
      augcp like bseg-augcp,
      vbeln like bseg-vbeln,
      end of it_acct.
data: begin of it_acct1 occurs 0,
      belnr like bkpf-belnr,
      cpudt like bsad-cpudt,
      vbeln like bseg-vbeln,
      end of it_acct1.
select belnr cpudt vbeln into corresponding fields of table it_acct1
              from bsad where cpudt in s_cpudt.
Now I want to move the data from it_acct1 to it_acct . I have no data in it_acct now.
i want to move it_acct1-belnr to it_acct-belnr,
          move it_acct1-cpudt to it_acct-augcp,
          move it_acct1-vbeln to it_acct-vbeln.
Can someone help me how to code to move the data from it_acct1 to it_acct.
Regards,
D

Hi Dev,
Just add an additional line in Naren's code to get proper results at any time.
LOOP AT IT_ACCT1.
IT_ACCT-BELNR = IT_ACCT1-BELNR.
IT_ACCT-VBELN = IT_ACCT1-VBELN.
it_acct-augcp = it_acct1-cpudt.
APPEND IT_ACCT.
<b>CLEAR IT_ACCT.</b>
ENDLOOP.
If you didnt include CLEAR statement, even if IT_ACCT1 doesnt have any values for all fields or few fields in the next record, it will take values of previous one and it may lead to improper results.So it is a good practise to have CLEAR statement after APPEND statement in LOOP...ENDLOOP.
Thanks,
Vinay
