Data from a file need to be read and mapped into a custom table of R/3

Hello all,
This is related to inbound to SAP ECC via SAP PI.
There is a requirement concerning PI part that data from a file need to be read and mapped into a custom table of R/3.
To have this scenario developed , do we have any other option than the Proxy ?
My understanding is as follows : File --> SAP PI --> Proxy
You suggestions are welcome.
Regards,
Rachana

Hi Ravi,
As suggested by Inaki, you can use proxy communication in recever.
but you can also use the below
FILE -----> PI -------> PROXY
RFC
IDOC
to communicate to ECC system.

How to recover data from .bkf files made when os was XP Proffesional into the system when it is windows7

Hello Sir/Madam,
Previously I was using Microsoft Wndows XP Professional,with version: 5.1.2600 Service Pack 3 Build 2600.
I took .bkf files by using the Backup utility (i.e. Start -> All Programs -> Accessories -> System Tools and then click Backup)
And paste it to my external hard disk.
Then I used OS :Microsoft Windows 7 Professional(Version 6.1.7600 Build 7600).I formated my system deleted all the partitions and created new partions and installed Windows 7.
Now I have the .bfk files in my external hard disk and I want to recover my data from that .bfk files made from xp-sp3 pc to windows 7.
Plz help me.....
I downloaded Windows NT Backup - Restore Utility and tried to install NtBackupRestore_x86.msi .But it will not installed in Windows 7 with a message that this requires Removable Storage Management. Since RSM is not included in Windows 7 how does
one access old Backups from Windows XP?
Will the NtBackupRestore program be updated to be compatible with Windows 7? plz help................................

Yes, you need to first install Removable Storage Management software before installing NT-Backup.exe in Windows 7. To know more about restoring backup file, you can read this post: http://belanalavade.blog.com/2014/04/15/how-to-repair-damaged-bkf-file/
Berdooook
No. You do not need to install Removable Storage Management in Windows 7 to read NT backups!
You go to http://support.microsoft.com/kb/974674 and download the package for Windows 7 that Microsoft has published specifically for this!

The short answer is: "Yes, of course." But you are going to have to do the legwork and learn LabVIEW basics before we can offer meaningful help.

Urgent help needed in inserting data into a custom table in oracle WorkFlow

Hi
I am trying to get data from the WF and insert into a custom table..
I read that workflow procedures WONT allow commits...
Oracle Workflow will not support autonomous commits in any procedure it calls directly. If you need to perform commits, then embed your SQL in a subprocedure and declare it as an autonomous block. This subprocedure must be capable of being rerun. Additionally, note that Oracle Workflow handles errors by rolling back the entire procedure and setting its status to ERROR. Database updates performed by autonomous commits cannot be rolled back, so you will need to write your own compensatory logic for error handling
Have anyone did this..
Please give me some idea ...It is urgent
I am getting data using getitemattribute..and try to insert it into a custom table

Reading in data from a file

Hi,
I am tring to read data from a file into my Web Service program. Its a plain text file with item descriptions and price info etc. At the moment I'm trying BufferedReader in = new BufferedReader(...) but I keep getting an exception with Tomcat not being able to locate my file.
Should there be a specific location for files such as this? Or do I need to add a path to a properties or build file? I have tried many different system locations.
I've tried to follow the Sun coffee bean example, but I have found it very complex and would appreciate a clear simple answer.
This is driving me crazy and any help would be much appreciated.
//Daniel.

public static void main(String argv[]) {
     try {
          String filename="absolute path to some file";
          BufferedReader in = new BufferedReader(

          String line;
          while ((line=in.readLine()) != null)
System.out.println(line);
     catch (Exception e) {
          System.out.println(e.toString());

Reading Unicode data from a file...

I am writing an application that needs to read some configuration data from a file. An end user edits the configuration file to provide the configuration data. The Java code reads this file and uses the configuration data supplied by the user.
The user can also save non-ascii characters as part of the configuration data. hence, I do not want to use java properties files. What are the other options available that allow me reading Unicode data into my Java code and will also allow user to save the configuration file as Unicode?

Java characters are Unicode characters. Read file data that consists of Unicode characters as Java characters or strings.
You can read the data as primitive char values using the DataInputStream class. The InputStreamReader class can also read Unicode (UTF-16) data.
Data can be written using the OutputStreamWriter class.

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.

Hi all,
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

<b>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
</b><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

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 :)
