hi all,
can any body provide code how to read data from flat file which is in application server.
thanks in advance

hi,
chk this sample code.
parameters: p_file like rlgrap-filename obligatory
default '/usr/sap/upload.xls'.
types: begin of t_data,
vbeln like vbap-vbeln,
posnr like vbap-posnr,
matnr like vbap-matnr,
werks like vbap-werks,
megne like vbap-zmeng,
end of t_data.
data: it_data type standard table of t_data,
wa_data type t_data.
open dataset p_file for output in text mode encoding default.
if sy-subrc ne 0.
write:/ 'Unable to open file:', p_file.
else.
do.
read dataset p_file into wa_data.
if sy-subrc ne 0.
exit.
else.
append wa_data to it_data.
endif.
enddo.
close dataset p_file.
endif.

Reading data from flat file Using TEXT_IO

Dear Gurus
I already posted this question but this time i need some other changes .....Sorry for that ..
I am using 10G forms and using TEXT_IO for reading data from flat file ..
My data is like this :-
0|BP-V1|20100928|01|1|2430962.89|27|2430962.89|MUR|20100928120106

Here each column is separated by | . I want to read all the columns and want to do some validation .
How can i do ?
Initially my requirement was to read only 2 or 3 columns so i did like this ...

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.

Extra column to be added while importing data from flat file to SQL Server

I have 3 flat files with only one column in a table.
The file names are bars, mounds & mini-bars.
Table 'prd_type' has columns 'typeid' & 'typename' where typeid is auto-incremented and typename is bars, mounds & mini-bars.
I Import data from 3 files to prd_details table. This table has columns 'pid', 'typeid' & 'pname' where pid is auto-incremented and pname is mapped to flat files and get info from them, now i wanted the typeid info to be received from prd_type table.
Can someone please suggest me on this?

You can get it as follows
Assuming you've three separate data flow tasks for three files you can do this
1. Add a new column to pipeline using derived column transformation and hardcode it to bars, mounds or mini-bars depending on the source
2. Add a look task based on prd_type table. use query as
SELECT typeid,typename
FROM prd_type
Use full cache option
Add lookup based on derived column. new column -> prd_type.typename relationship. Select typeid as output column
3. In the final OLEDB destination task map the typeid column to tables typeid column.
In case you use single data flow task you need to include a logic based on filename or something to get the hardcoded type value as bars, mounds or mini-bars in the data pipeline
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs

Ssis - import data from flat file to table (sql server 2012)

i have create a ssis for importing data from flat file to table in sql server 2012.
but i got the below error for some column in data flow task.
error: cannot processed because than one code page (950 and 1252)
anyone helps~

Hi,
The issue occurs because the source flat file uses ANSI/OEM – Tranditional Chinese Big5 encoding. When processing the source file, the flat file connection manager uses code page 950 for the columns. Because SQL Server uses code page to perform conversions
between non-Unicode data and Unicode data, the data in the code page 950 based input columns cannot be loaded to code page 1252 based destination columns. To resolve the issue, you need to load the data into a SQL Server destination table that includes Unicode
columns (nchar or nvarchar), and convert the input columns to Unicode columns via Data Conversion or the Advanced Editor for the Flat File Source at the same time.
Another option that may not be that practical is to create a new database based on the Chinese_Taiwan_Stroke_BIN collation, and load the data to non-Unicode columns directly.

Loading transaction data from flat file to SNP order series objects

Hi,
I am an BW developer and i need to provide data to my SNP team.
Can you please let me know more about loading transaction data (sales order, purchase order, etc.,) from external systems into order based SNP objects/structure. there is a 3rd party tool called webconnect that gets data from external systems and can give data in flat file or in database tables what ever required format we want.
I know we can use BAPI's, but dont know how. can you please send any sample ABAP program code that calls BAPI to read flat file and write to SNP order series objects.
Please let me know ASAP, how to get data from flat file into SNP order based objects, with options and I will be very grateful.
thanks in advance

I need some help. I have a Excel file with set of name, phonenumbers . I want to know how to display the data using Webdynpro. Could some one help me. help is appreciated and I promise to award points for right answer.
Thank you

Hi
i can explain you to read data from Excel file
First You have to download the jxl.jar file. You can get this file from the Below site
<a href="http://www.andykhan.com/jexcelapi/download.html">jexcelapi jar</a>
It will be in Compressed Fromat So Unzip it to get the Contents
After Unzipping The File You will get a Folder (jexcelapi/jxl.jar)
Now in NWDS open web dynpro explorer, Right Click Your Project, a popup menu will appear and in that click Properties
You will get window displaying your Project Properties
On Left Side of the window You Will Find "Java Build Path"
Click That "Java Build Path" and you will get 4 Tabs Showing ( Source,Projects,Libraries,Order and Export)
Click Libraries Tab
You will find options many options buttons
In that click the Button "Add External Jars"
You will get Window in order to fecth the jxl.jar file from the location you had stored
After selecting the jxl.jar i will get displayed and click ok
Now Open Navigator
Open Your Project
You will find Lib folder
Copy the jxl.jar to that lib folder
Note : You cannot Read the Content from the excel file directly
First You Have to copy that file to the Server,
And from the Server you can get the file absolute path
With the absolute path you can read the contents of the Excel file
You have to save the Excel file as .xls Format and Not as xlsx format i will not accept that...
You have Upload the Excel file from the Server Using the File Upload UI Element
This Coding will extract 3 columns from the Xls File

Failed to read data from report file Reason: The table could not be found.

BO Enterprise XI R2, cannot publish crystal reports using the publishing wizard.
Failed to read data from report file Reason: The table could not be found.
Any ideas to get around this would really help out.

Connection used Views, ODBC System DSN is setup properly.
Approach for import from business view manager and import wizard. both methods failed to import the Business View and underlying reports.
I figure I may have imported the Business View wrong? From Business View Manager I exported from my dev server then imported to prod server.
Apparently I learned exporting my business view also includes the Data Connections that the Business Views are dependent upon.
So which ever folder you specify it copies it there. Originally the all Data Connections Resides on the root folder. To return it to the original location. I deleted what I had exported. Exported this time to the root folder, then only deleted the business views, foundation, elements. Then exported again to the folder where I intended then only deleted the Data Connection.
Makes any sense? So I then had to re point the business views and all the dependent objects to the data connection that resides in the root folder.
I tested the connection, it works fine. I properly updated my crystal reports to the business view in production. Did a sample extract it works as expected.
However when i try to publish, either from Crystal or Publish wizard i get the same error?
As a work around i am thinking, after updating the business view in the crystal reports, shall i re map the fields?? or reexport the business views again?
Any help will be surely appreciated.

Wrong century for the dates from flat file

I am in the process of uploading the data from flat file ( aka CSV) into oracle via external table .
All the dates have the year of 20xx. My understanding was 51-99 will be prefixed with 19 ( such as 1951 - 1999) and 00-50
will be prefixed with 20 ( such as 2004 ... )
The column below ( startdate ) is of timestamp .
Is my understanding wrong ?

I literally typed the sql ( as I did not copy & paste SQL / resultsets ) . I did use to_char in my original sql . I don't want to expose the real table . thats why I was giving the made up test case. If you carefully the SQL and the equivalent result sets ... you would have noticed .
Here is the SQL used ( of course , I have changed the table name ) ...
select to_char(startdate , 'mm/dd/yyyy') sdate, startdate from t
SDATE STARTDATE
09/18/2090 18-SEP-90 12.00.00.000000 AM
The flatfile had the value of 091890 as the data .

Loading data from flat file to ODS

Hi Experts,
I have a developed a report, in which Flat file is the datasource and data target as DSO.
Here I have one requriment to Increatment the counter value in TVARVC table after every load compleate.
Can this be done thru Process chain? I belive this can be done thru process chain by creating variable.
If this can be done thru Process chains can any experts send me sample examples code.
Thanks In Advance.

Hi sridhar,
     We have a similar scenario in which we will load data from flat file to datasource the file name (x_20081010.dat) of such format being fetched from the low value of the TVARVC table ... once successfully executed we had program to increment the value of low which increments by one day adn the next day the file with that will be placed in the application server...
    U can create a abap program varaint and attribute for that and u can achieve that.... this is sample code which searches for the string and after some coding i.e once ur file has been loaded successful code u can write similar code to increment or counter values which u are asking for...
search s_tvarvc-low for '20'.
        if sy-subrc ne 0.
          sy-msgty = 'E'.
          sy-msgid = 'ZWM1'.
          sy-msgno = '000'.
          sy-msgv1 = 'Unable to find DATE to increment'.
          raise unable_increment.
        else.
          w_date = s_tvarvc-low+sy-fdpos(08).
          w_nextdate = w_date + 1.
          replace w_date with w_nextdate into s_tvarvc-low.
          modify tvarvc from s_tvarvc.
        endif.

# 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.
# You may also consider using Database Configuration Assistant tool (DBCA)
# to create INIT file and to size your initial set of tablespaces based
# on the user input.
