OHD vs APD - Flat file

Hi Gurus,
I have cube which has some amount of data . I need to send the data to flat file.
I have 2 option :
1. OHD.
2. APD.
In both way i can send the data to flat file. Which one i need to choose either APD or OHD.
I read from some document that SAP has recommened to OHD for huge amount of data. But i can able to send the data using both the ways and the time difference is also not that much.
In this case ,which one i need to choose and in background how the data is retrived. SOmebody asked to choose APD and somebody says OHD. Please guide me in proper way..
Thanks in advance !!!

Hi,
This discussion is already happened and I think you have got much information on both the techniques, as  mentioned that there is no much time difference in loading then you can go ahead with whichever approach you are comfertable with.

  • APD - Query output on to a Flat file

    All
    We are on BI 7.0 with SP13 and NWS 12. I am trying to create a new APD with source as "Query" built on Info object and target as "Flat File". There is no requirement of transformation so I am trying to map directly from Source to Target with a direct link with out using any transformations in between,
    I could check and found no errors in APD definition and when I run APD, the file is getting created both on application server and local workstation but with 0 records.
    The volume of records are expected to be around 4 millions on this query and am just wondering why APD is not writing any data on CSV file.
    Pls let me know the following;
    - What is wrong in the above process and why it is not writing data on to flat file
    - Can APD handle volume of 4 million rows even though job runs in the background?
    Your inputs in this are highly helpful and thanks for your time to provide solution.
    Thanks - Sriram

    Hi
    Thanks for your reply and I could solve this issue and found the root cause.
    The very purpose of this APD is to provide a list of business partners to an upstream systerm with few attributes and in this process one of my consultant has deactivated the key figure in the query which is an input for APD process.
    When the key figure is inactivated ( this is the only key figure in the query ), APD does not recognize query as a valid one and sends out an error message.
    When we re activate the key figure ( I have hidden this later using APD transformations to hide the column and send output to a flat file on to unix server ) in the query, the APD runs fine and could deliver the output in flat file.
    Thanks

  • Query Output to download in flat file through APD  or other means?

    Hello Experts,
    I am currently on BW3.5 system and have requirement to load query output in flat file in .csv format. I checked the option of APD but looks like we cant directly load the query output in flat file like in APD (BW  3.5 system) .
    One way i can think of it...load  the query output in transactional ODS and built an infospoke on it to write into flat file.
    Please advice if there are any better methods to store the query output in flat files.
    Thanks!

  • Re-arrange the flat file out put in APD

    Hi Guys,
    I am loading data in APD,soruce is Query and target is Flat file.i want to re-arrange the out put file.
    Let me know what are the possible ways to re-arrange the columns in the out put flat file.
    Regards,
    Jayapal

    There are three ways to do this:
    1. Use Hide or Rename Columns (Projections) under Transformations in between the query and the flat file (recommended method)  
    Under the field selection tab..transfer the fields to the right pane in the order you wish to view thwm in.
    2.Drag and drop a routine
    Go to source fields tab
    Move the entries in the right to the bottom left 'Source Fields' pane.
    Then go to the Target field tab.
    Right Click on the row and click unfreeze columns
    Now you can drag & Drap and re-arrange the fields.
    Insert the routine in between query and Flat file
    3.  Change the order of the fields in the Query Definition( Not Recommended)
    Cheers!

  • Saving query results to a flat file

    Hello Experts!
    We have a very specific issue on our current project and I would like to know if any of you have ever done something similar. We are taking query results from BW (after complex calculations, some based on SY-DATE) and saving them to flat files to transfer to a SQL database structure on the Enterprise Portal. From here, the portal team renders the information into more "static" dashboards that include mouse over features and even limited drilldown (i.e. no matter where a user clicks the report always drills down on profit center)
    There are many reasons why the model is set up as such (mostly training of executive level end users), and even though it doesn't mesh with the idea that BW could do this work on its own, we have to work with what we have.
    We have come up with 3 possible ways to save this data to flat files and hopefully someone can tell us which might be the most effective.
    1.) Information Broadcasting. If we broadcast XML files to the portal, will the portals team be able to read that data into a SQL database? Is there another way to use broadcasting to create and send a flat file to specific location?
    2.) RSCRM_BAPI. This transaction seems to not support texts.
    3.) Open Hub. In order to get the open hub to work, we first have to save all of our query results to direct write data store objects using APD. (calculations based on current date, for example, would require daily full loads to the underlying data providers otherwise.)
    What is the best way to accomplish this? Is information broadcasting capable of doing this?
    Thanks!

    Hi Adam,
    Do you have to use flat files to load the information to a SQL database? (if so maybe someone else has a suggestion on which way would be the best).
    I try to stay away from flat file uploads as there is a lot of manual work involved. May I suggest setting up a connection to your SQL table in the DBCON table and then writing a small abap program to push data into the SQL database (which you can automate).
    1) Use APD to push data into a table within BW.
    2) Go to transaction SM30 > table DBCON and setup a new entry specifying the conncection parameters to your SQL database.
    3) In SE38 Write an ABAP program along the folloing lines (assuming the connection you set in DBCON is named conn1:
    data: con_name like dbcon-con_name
    con_name = 'conn1'.
    exec sql.
      set connection :con_name
    endexec.
    ****have a select statement which reads data from your table which the data is saved from the APD into an internal table**********
    ****loop on the internal table and have a SQL insert statement to insert the records into the SQL table as below******
    exec sql.
    insert into <SQL TABLE> (column names seperated by ,)
    values (column names of the internal table seperated by ,)  if the internal table is named itab the columns have to be specified as :itab-column1
    If you decide to take this approach you may find more info on DBCON and the process in sdn. Good Luck!

  • What is the best way to export the data out of BW into a flat file on the S

    Hi All,
    We are BW 7.01 (EHP 1, Service Pack Level 7).
    As part of our BW project scope for our current release, we will be developing certain reports in BW, and for certain reports, the existing legacy reporting system based out of MS Access and the old version of Business Objects Release 2 would be used, with the needed data supplied from the BW system.
    What is the best way to export the data out of BW into a flat file on the Server on regular intervals using a process chain?
    Thanks in advance,
    - Shashi

    Hello Shashi,
    some comments:
    1) An "open hub license" is required for all processes that extract data from BW to a non-SAP system (including APD). Please check with your SAP Account Executive for details.
    2) The limitation of 16 key fields is only valid when using open hub for extracting to a DB table. There's no such limitation when writing files.
    3) Open hub is the recommended solution since it's the easiest to implement, no programming is required, and you don't have to worry much about scaling with higher data volumes (APD and CRM BAPI are quite different in all of these aspects).
    For completeness, here's the most recent documentation which also lists other options:

    Hi,
    If i assume correct you want to supply ur data into flat file on daily basis.
    You can use APD to Do this both in BW3.5 and & BI 7.0.
    Creating dataflow in APD is pretty simple like process chain.
    What you can do is select "table" as a data source and "Flatfile" at datatarget (both on client server or on desktop).
    You will get APD option in RSA1 screen.
    After creating this APD you can schedule it on daily basis etc.
    Thanks and regards

  • Publishing data from a Cube to a flat file

    Hi,
    I need to publish data from a Info Cube to a flat file. The requirement here is a variable selection will be specified (fiscal periods, product group) and based on the selection chosen the data should be generated in the flat file. What are the options I have to do this.
    I know using an APD we can generare data into a flat file but how can we have a variable selection for that data generation. Plus is there a limit on the number of data records we can generate
    using an APD
    Apart from the APD what other options do we have?
    Thanks
    Rashmi.

    Hi Rashmi,
    Please follow below steps by using open hub destination
    1. Go to RSA1 -> Select Open Hub Destination from Left pane.
    2. Right Click on the info area under which you want to create Open Hub and Select Create Open Hub Destination.
    3. Give Name, Description for the Open Hub.
    4. In template, Select Object type as "Infocube" and give the name in Name field. Press Enter
    5. In Destination tab, Select Destination type as File. Give all other details like Filename, Directory etc.
               In the Destination tab select type as FILE and give SEPARATOR as comma(,) and not as semi-colon(
                 and observe that the values iin the file will be displayed in different cells
    6. In Field Def tab, you will see all the Fields that can be transferred from Source infocube to File.
    7. Save the open hub destination.
    8. Right click on created open hub, Select Create transformation. Give Source of transformation as the infocube. Make transformation as needed.
    9. Again right click on the open hub, Select Create DTP. Then Save and Activate the DTP.
    10. Schedule the data extract as required.
    Option2:
    You can download in LISTCUBE tcode as well.
    Hope this helps.

  • Refreshing the data in a flat file

    Hi
    I am working on data integration.
    I need to fetch data from Oracle data base and then write it to a flat file.
    It is working fine now,but for the next fetch I don't need the old data to remain there in the file.The data should get refreshed and only the newly fetched data should be present.
    After the data is written to the flat file can i rename the file?
    I need the format of the file to be 'File_yyyyMMDDHHmmss.txt'.
    My final question is how should I FTP this to the target?
    Please help me on this as soon as possible since this is needed in an urgent part of the delivery.

    All you ask is achievable:
    1) The IKM SQL to file has a TRUNCATE option, which will if set to YES, will start from a clean file.
    2) You could rename the file after writing it, but why not just write it with that name? If you set the resource name to be a variable, (e.g. #MyProj.MyFilename), and be sure to set the variable in the package before executing your interface, you should be able to get the file you want. Otherwise, you can use the OdiFileMove tool in your package to rename the file.
    To set the name of the variable you can use a query on the database (if you are using Oracle, something like SELECT 'File_'||TOCHAR(SYSDATE) from DUAL.)
    3) ODI has ftp classes built in- you can find the doc under doc\webhelp\en\ref_jython\jyt_ex_ftp.htm
    Hope this helps

  • Loading multiple flat file at a time.

    hi experts,
    I am having 15 flat files with same data structure.so how do i load all the fileswith out creating 15 info packges .
    ( say all the files are on the desktop.)
    I had seen the option that ABAP code an be written in info package in extraction tab.
    Can any one share me the abap code
    Regards
    Laxman.

    You can write dynamic code using ABAP if your number of flat files are not fixed...but if you have to 15 flat files always just creating multiple infopackages.
    For code, you have to store file names/name pattern in some table and reading it at run time. You can use function modules starting with BAPI_IPAK* to create/change/start template IP like BAPI_IPAK_START. You can set IP parameters at run time using FM RSBATCH_MAINTAIN_PAR_SETTINGS.

  • InfoSpoke Flat File Extract to Logical Filename

    I'm trying to extract data from an ODS to a flat file. So far, I've found that the InfoSpoke must write to the application server for large data volume. Also, in order for the InfoSpoke to transport properly, I must use logical filenames. I've attempted to implement the custom class and append structure as defined in the SAP document "How To... Extract Data with OPEN HUB to a Customer Defined Logical Filename". I'm getting an error when attempting to import the included transports (custom class code). It appears to be a syntax error. Has anyone encountered this, and, if so, how did you fix it?

    Hello.
    I'm getting a syntax error also.  I did not import the transport, but applied the notes thru the appendix.  When I modified the method "GET_OBJECT_REF_INT" in class CL_RSB_DEST as below, I get a syntax error on the "create object" statement.
        when rsbo_c_desttype_int-file_applsrv.
    *{   REPLACE        &$&$&$&$                                          1
    *\      data: l_r_file_applsrv type ref to cl_rsb_file_applsrv.
          data: l_r_file_applsrv type ref to zcl_rsb_file_logical.
    *}   REPLACE
          create object l_r_file_applsrv
            exporting i_dest    = n_dest
                      i_objvers = i_objvers

    The obligatory parameter "I_S_VDEST" had no value assigned to it.

  • Dynamic file name from input payload (RFC 2 flat file)

    Hi,
    I have an RFC to flat file scenario. The output flat file has not an XML structure, it's just a plain text file generated with abap mapping.
    In my source interface (RFC), I have a field called <FILENAME>, I want to use the value of that field to create the target file using dynamic file name. But if  in variable substitution I use payload:ZRFC_NAME,1,FILENAME,1 It doesn't work because the dynamic variable substitution try to access to output payload, not the source one...
    What can I do?

    Hi Marshal,
           You can add a extra node to your target strucutre like
    FileName- Node
    --FileName - Element.
    do the mapping from the field filename of RFC to FileName field in u r target strucure. And use this  field path at Refrence in variable subtituion.
    In the Content converison add the Name & Values as below
    FileName.fileldNames -- FileName
    FileName.fieldFixedLengths -- 0
    FileName.fixedLengthTooShortHandling -- Cut
    So the extra field in u r target structure would not populate in u r target text file.
    Cheers

  • Non English Charaters in Flat file(Note pad)

    Dear Friends,
    I have a flat file from presentation server which needs to be uploaded and do some validations on that file based on the data existing.
    I have some Russian language words in that file. E.g: "ОЩИ В ПОДГ". If this word exists in the file i need to get some other data from a database table. But when trying to check for the word, these characters are appearing as junk characters like ####&^^.
    I tried logging into RU language also, but still not working. And also tried changing the file as type Unicode, ASCII and also not worked.
    Please let me know how to get identify these words to see the exact russian words.
