How to store the flat file data into custom table?

Hi,
Iam working on inbound interface.Can any one tell me how to store the flat file data into custom table?what is the procedure?
Regards,
Sujan

Hie
u can use function
F4_FILENAME
to pick the file from front-end or location.
then use function
WS_UPLOAD
to upload into
AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_file.
CALL FUNCTION 'F4_FILENAME'   "Function to pick file
    EXPORTING
      field_name = 'p_file'     "file
    IMPORTING
      file_name = p_file.     "file
CALL FUNCTION 'WS_UPLOAD'
   EXPORTING
     filename                       = p_file1
    TABLES
      data_tab                      = it_line
*then loop at it_line splitting it into the fields of your custom table.
loop at it_line.
          split itline at ',' into
          itab-name
          itab-surname.
endloop.
then u can insert the values into yo table from the itab work area.

How to upload the flat file records into internal table by position?

Hi
I have a flat file which has 7 records in each row and they are NOT provided with CSV or Tab demilited...
They are continous text without spaces....
but i know the fixed length of each field Eg : 1st field 7 char and seconc field 3 char and so on...
How can i upload this file into internal table by reading positions of each field...I know we can use GUI_UPLOAD and Read dataset and Open dataset...
But please let me know to read the file with the fixed postions and load into internal table...
Thanks in advance
MM

Hi
As per my knowledge i dont think thr is some function module or so to read with a fixed positions.
You can use the below method if you think this is the best way.
Suppose your file has
types : begin of ty_itab,
            field1 type char7,
            field2 type char3,
            field3 type chat3,
            field4 type char3,
            end of ty_itab.
types : begin of ty_upload,
             str type string,
            end of ty_upload.
data : it_itab type standatd table of ty_itab,
          it_upload type standard table ot ty_upload,
          wa_itab type ty_itab,
          wa_upload type ty_upload.
use gui_upload.get the data in it_upload.
here you know that u have first 16 charcters makes a first row n then next 16 charcters next row
Loop at it_upload into wa_upload.
   v_len = strlen ( wa_upload ).
   v_len = v_len / 16.
    You get number of rows per record ,if it is decimal value make it final value if 3.9 make to 4.
    do v_len times.
      wa_itab = wa_upload.
      By this only first 16 characters are moved and respective fields will get a value.or else u can use offset
       wa_upload+0(16).
      append wa_itab to it_itab.
      Now shift 16 characters using shift command in wa_upload.
    enddo.
endloop.
Hope this syntax help you to resolve your issue.May be something i have missed .Right now i don't have sap system to send you the full correct syntax code.
Cheers

Faisal,
When you read the multiple recordset strucutre file then each record in txt file should have an header from which you can identiy which segment it should go.. and you identiy it by using the keyfiledValue in file adapter
<root>
<header1> 0..1
<f1>
<f2>
<f3>
<header2> 0..1
<f4>
<f5>
<f6>
<item> 1..unbounded
<f7>
<f8>
<f9>
<f10>
<f11>
<f12>
</item>
for this input file
abc def ghi jkl mno pqr
123 123 123 123 123 123
456 456 456 456 456 456
abc def ghi can be read using the file adater to header 1 usinfg key field value, but using the same file adapter you cannt put GHI into header2.
else you should read whole row abc def ghi jkl mno pqr in single filed and write an UDF to split data to header1 and Header 2
similarly you have to take care for item records also
if your inout file is something like this
abc def ghi
jkl mno pqr
123 123 123 123 123 123
456 456 456 456 456 456
abc identifies to Header 1
JKL for Header 2 so on...
read the whole line in single field and write UDF to Split to header 1 and header 2 similary for item.

Hi Sunil
Hope you can check whether you are loadig the flat file data from application server or Client workstation.
May be if you are loading from Client work station you will face problem of this type.
Try to check if any change in format in the file.
at the end of the file delete the spaces.

How to query the flat files?

Hi
How to query the flat files that are used in Etl From EBS source.

That can be done in OBIEE. Save the flat file as .csv format. Then go to ODBC Administrator on windows machine where you BI server is running, and create an System DSN and select "Microsft Access Text Driver (*.txt, *.csv)" as driver type.
Next, import tables in RPD using this ODBC connection. Rest of the steps as same as building model from a table source.
Hope this helps.

How to list the JAR files loaded into the Oracle Database ?

How to list the JAR files loaded into the Oracle Database ?

From 11.1 onwards, the below two views are available to identify the jar files loaded into the Database.
JAVAJAR$
JAVAJAROBJECTS$
By querying the JAVAJAR$ view you can know information about the JAR files loaded into the Database and using JAVAJAROBJECTS$ view you can find all the java objects associated with the given JAR file.
These views are populated everytime you use LOADJAVA with "-jarsasdbobjects" option to load your custom java classes.
But unfortunately this feature is available only from 11.1 onwards and there is no clear workaround for above in 10.2 or earlier.

How to store the pdf file

hi all,
i need a pl/sql code to store the pdf file into the oracle database using blob.
help me.
Thanks in advance

My first question is "where is the PDF file located"? If the answer is "on a file system accessible to the Oracle database" Then you can use directory objects and the DBMS_LOB package. It would look something like this:
as SYS user do:
-- assume the PDF files are in /data/documents <font face="tahoma,verdana,sans-serif" size="1" color="#000">files</font>ystem directory
create or replace directory pdfdir as '/data/documents';
grant read on directory pdfdir to <USER>;
as USER do:
create table mydocs (id integer primary key, doc blob);
declare

insert into mydocs values(1, empty_blob()) returning doc into b;

How to store a text file in a hash table in C#?

I am fairly new to c#. I am creating a console application project for practice. I am supposed to create a program that reads a text file (it's a poem), store it in a hash table, have two different sorts, and unhash the table. I managed to get the poem read
by using streamwriter, but now I am not sure how to store it in a hash table.
I'm not sure if I am doing this hash table correct, but I made my hash table like this to store the text file:
Hashtable hashtable = new Hashtable();
hashtable[1] = (@"C:\\Documents\\Datastructures\\Input\\Poem");

Hi,
Hashtable in C# represents a collection of key/value pairs which maps keys to value. Any non-null object can be used as a key but a value can. We can retrieve items from hashTable to provide the key . Both keys and values are Objects.
Here is a sample about Hashtable,
Hashtable weeks = new Hashtable();
weeks.Add("1", "SunDay");
weeks.Add("2", "MonDay");
weeks.Add("3", "TueDay");
weeks.Add("4", "WedDay");
weeks.Add("5", "ThuDay");
weeks.Add("6", "FriDay");
weeks.Add("7", "SatDay");
//Display a single Item
MessageBox.Show(weeks["5"].ToString());
//Search an Item
if (weeks.ContainsValue("TueDay"))
MessageBox.Show("Find");
else
MessageBox.Show("Not find");
//remove an Item
weeks.Remove("3");
//Display all key value pairs
foreach (DictionaryEntry day in weeks)
MessageBox.Show(day.Key + " - " + day.Value);
>>I managed to get the poem read by using streamwriter, but now I am not sure how to store it in a hash table
Hashtable hashtable = new Hashtable();
hashtable[1] = (@"C:\\Documents\\Datastructures\\Input\\Poem");
But follow your scenario above, you just store a string path to hashtable not a file.
About saving data to a file, you can use the following code.
// Write the string to a file.
System.IO.StreamWriter file = new System.IO.StreamWriter("c:\\test.txt");
file.WriteLine(lines);
file.Close();
Best wishes!

Mass upload of data into Custom table

Hello all,
            I made search in SDN and could not find the best solution to my problem and hence posting .
           What is the best way for Mass upload of data into Custom database table ?
           I think LSMW would not be a viable option as it would take longer time .
           Locking of the table also needs to be taken care.
           PLease let me know if you have a alternative to this and the best way to do this .
Comradely,
K.Sibi

Hi Sibi,
See Lock objects are required when we enter the data through screen level, or multiple users should not enter the data at same time.
Create one Lock object in SE11, It automatically creates FM.
DEQUEUE_EYTEST2                Release lock on object EYTEST2
ENQUEUE_EYTEST2                Request lock for object EYTEST2
Call these FM in your program.
