Need to read a field from flat file

Hi All,
    In flat file i have  one field which may contain 100 enteries separated by delimanator ',' (comma).  There can be 1 , 10 or 100 enteries.   I need to put them in the internal table . Please suggest me .
    I have used the below logic .
i split the field in 100 variables and then appending the internal table . the problem here is even if there is only one entry , the logic will append 99 blank enteries .  so can any one suggest , is there any other way do it . any Functon Modules available .
Thanks.

Hi Chetan,
If i understand your requirement it is as below,
Flat file.
1,2,3,4,5,6,7,8,9,....
1,2,3,4,5,6,7,8,9,....
1,,,,,,,,,,,,,,,,,,,,
Now you read the first line and split into an itab of type string, and you are worried about the third line where not all the fields have values and end up creating blank entries. to fix this, simply
Sort the Itab, and use delete itab statement with the where clause as where column is ''.
This should solve it.
types: begin of t_data,
            line type string,
           end of data.
data: li_file_line type standard table of t_data.
split l_file_line at ',' into li_file_line.
delete li_file_line where line = ''.

  • Short dump while reading a currency field from Flat file into internal tabl

    Hi,
    I am getting a short dump........saying number conversion dump (while reading a currency value into field in internal table from a fixed lenght flat file).........
    Do I need to use a string variable to get the value from flat file or how ??
    Please suggest.

    Santosh,
    Thanks for your inputs,
    But my internal table type is of DEC (5,2) , I am getting that... it needs to be of type 'C'. Can you suggest.
    Ex :
    MOVE wa_temp-infile_string+106(8)  TO wa_item-QT_PERCENT
    This didnt work
    so i tried moving into a seperate variable
    MOVE wa_temp-infile_string+106(8)  TO v_percent.
    and then write to
    WRITE v_percent to  wa_item-QT_PERCENT.

  • Loading Date fields from flat file to Oracle tables

    Hi,
    I have a flat file with a few date columns. I have given the format for the date field while creating the data store for the flat file. The format I used is 'YYYY-MM-DD'.
    But I get an error when I execute it after associating the module with LKM & IKM.
    The error message is as follows:
    org.apache.bsf.BSFException: exception from Jython: Traceback (innermost last):
    File "<string>", line 3, in ?
    OS command has signalled errors
    Can anyone help me out.
    Thanks

    At the time of DataStore creation. You take that date field as string.
    After this, in interface, when you map this date field with table field. You should use CONVERT(<field name>,DATE) in expression editor.

    Hi,
    This is the procedure.
    1. Create m-data with or without attributes.
    2. Create infosource .
        a) with flexible update

    3. Create transfer rules and assign tyhe names of m-data and attribute in "Transfer rules" tab and transfer them to communication structure.
    4. Create the flat-file with same stucture as communication structure.
    5. if chosen direct update then create infopackage and assign the name of flat-file and schedule it.
    6. if chosen flexible update the create update rule with assigning name of the infosource and the schedule it by creating infopackage.

  • Kinect Explorer WPF C# read depth data from the file and conversion to skeleton

    Hello,
    I am using Kinect sensor to do some research on biometrics. Since it is impossible to find people to collect some samples, I would like to use samples from the TUM - GAID database, where there exist Color View and Depth View (in .raw format) samples. Therefore,
    I need to read these samples from the file and do a batch processing, instead of performing real-time collecting of samples (where I can take automatically the Skeleton view using the Kinect SDK). So, I need help on
    1. Reading the data from the file (instead of activating the Kinect sensor) and give this data as an input for conversion to a skeleton
    2. Read the .raw files 
    Thank you very much
    Kind regards

    Hiya,
     I doubt this forum, C Sharp, will provide much help. You are asking about the Kinects system not C#
    language. However, you can try this link; http://kinectforwindows.codeplex.com/
    Hope this help. Thanks :)

    I have to check the file :-
    Validation are 1st line should start from 0 else it should raise an error and insert that error into one table .
    The for 2nd line also same thing ..it should start from 9 else it should raise an error and insert that error into one table .
    Then the 3rd line should start from 1 else it should raise an error and insert that error into one table .
    After that i have to do a validation like i will read the 1st line 2nd column .. It should be like this BP-V1 else raise an error and insert that error to a table . Then i will check the 3rd column which is 20100928 , it should be YYYYMMDD format else same thing ERROR.
    Then like this for all columns i have different validation .......
    Then it will check for the 2nd line 3rd column . this is an account no .1st i will check it should be 12 char else ERROR .Then I will check that what user has imputed in the form.Like for example User putted 111111111 then i will check with this 000111111111 which is there in the 2nd line . I have to add 000 before that Account no which user imputed .
    Then the lines which is starting from 1 , i have to take all the 2nd column for all the lines which is starting from 1 and i have to do a sum . After that i have to compare that sum with the value in the 1st lines ( Starting from 0) 6th column . It should be same else ERROR ...
    Then same way i have to count all the lines which is starting from 1 . Then i have to compare with the 7th column of 1st line . It should be same . Here in this file it should be 9.

  • How to avaoid space while reading from flat file

    Dear all
    I am using forms 10g.
    I am reading data from flat file using Text_io.
    In my exception part i have written like this
    EXCEPTION
      WHEN no_data_found THEN
          CLIENT_TEXT_IO.Fclose(in_file);But if in my last line from the flat file is some other characters then it is taking that also .
    How can i avoid it ?
    Note :- Other characters means you cannot see like this , when you press SHOW ALL CHARACTERS button in the NOTEPAD++ then it will show ...

    My File is like this ABC . There is no extension like ABC.txt .
    And in the file if the last line if blank space is there then it is coming to exception part , but if TAB is there then it is not coming .

  • Loading a field of length( 60 and up to 2048) from flat file to BW.

    Hello,
    Can you please suggests ways by which we can load a field in flat file which is of length greater than 60 and up to 2048 digits to BW.
    Facts:
    We cannot have more than 59 length digits in an infoobject
    Observations:
    The idea of using multiple infoobject,ie for 2048 max length it will be 35 infoobjects is not acceptable by my client.
    So, can anyone suggests other ways in BW3.5 for loading a text of length up to 2048 from flat file to BW.

    Hi,
    If you have source field DD/MM/YYYY format, please try this code in the field routine.
    Data : lv_date(8) type C.
    lv_date0(4) = <Source Field Name>6(4).
    lv_date4(2) = <Source Field Name>3(2).
    lv_date6(2) = <Source Field Name>0(2).
    RESULT = LV_DATE.

    # Example INIT.ORA file
    # This file is provided by Oracle Corporation to help you customize
    # your RDBMS installation for your site. Important system parameters
    # are discussed, and example settings given.
    # Some parameter settings are generic to any size installation.
    # For parameters that require different values in different size
    # installations, three scenarios have been provided: SMALL, MEDIUM
    # and LARGE. Any parameter that needs to be tuned according to
    # installation size will have three settings, each one commented
    # according to installation size.
    # Use the following table to approximate the SGA size needed for the
    # three scenarious provided in this file:
    # -------Installation/Database Size------
    # SMALL MEDIUM LARGE
    # Block 2K 4500K 6800K 17000K
    # Size 4K 5500K 8800K 21000K
    # To set up a database that multiple instances will be using, place
    # all instance-specific parameters in one file, and then have all
    # of these files point to a master file using the IFILE command.
    # This way, when you change a public
    # parameter, it will automatically change on all instances. This is
    # necessary, since all instances must run with the same value for many
    # parameters. For example, if you choose to use private rollback segments,
    # these must be specified in different files, but since all gc_*
    # parameters must be the same on all instances, they should be in one file.
    # INSTRUCTIONS: Edit this file and the other INIT files it calls for
    # your site, either by using the values provided here or by providing
    # your own. Then place an IFILE= line into each instance-specific
    # INIT file that points at this file.
    # NOTE: Parameter values suggested in this file are based on conservative
    # estimates for computer memory availability. You should adjust values upward
    # for modern machines.

    Hi All,
    I am new to BI 7. Trying to create a cube and load data from a flat file.
    Successfully created the infosource and Cube (used infosource as a template for cube)
    But got stucked at that point.
    I need help on how to create transfer rules/update rules and then load data into it.
    Thanks,

    Hi
    right click on infosource->additional functions->create transfer rules.
    now in the window insert the fields you want to load from flat file->activate it.
    now right click on the cube->additional functions->create update rules->activate it.
    click on the small arrow on the left and when you reach the last node(DS)
    right click on it->create info package->extenal data tab->give your FLAT file path and select csv format->schedule tab->click on start.
    hope it helps..

    so he need a permanent solution
    with regards
    subrat

    Hi Subrat ,
    u can upload the data either ( Master /Transaction) data with the help of lsmw. for that all u need to do is go through the lsmw and do it. in that u can go Batch input recording/ BAPI/ IDOC any of that. here i am sending the LSMW Notes go through it and do the work.
    once u create the LSMW project then u can ask the data from user or u can explain the user about the program and can run the flat file to upload the data.
    if u require LSMW material Just send me blank mail from u. my mail id is [email protected]
    Reward if Helpful.
