Routine sample code for reading 2 fields from existing DSO

Hi Gurus,
I am a monkey when it comes to write ABAP code. I have one DSO-A where we store accounting info of purchading (from DS 2lis_02_acc) and one DSO-B getting data from 2lis_02_scl data source.
We need to write a rountine to read DSO-A for G/L account and populate DSO-B G/L account field.
Please provide me the sample code for this.
Warm Regards,
Anil

Hi anil,
Create a local table this is type of you source,
Data : LV_table TYPE XXXX
use the select statement to read the table of DSO .You have to use th active table for the dso that you want to read data from.
Select xxxfieldxxx FROM /BIC/A..........50
into lv_table where
filed name of of scheule line probably order no and item no .
<soruce-fields>-IOBELN = IOBELN
and <source-fields>-IOBELP = IOBELP.
Checke the techinal name i am not sure about it. It will be something like that.
Cheers mate

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 :)

Help is needed in my RMI code to read in data from input file

Hi All,
As part of my assignment, I have to develope a client/server application using RMI (not sure why????).
I am new to java and using after going through numerous examples I have come up a class on the server side
to read in the stored data. However during the search I can only display one item (2nd last one) not the entire list
available in the csv file. Any idea how I can fix this? Here is my code..
package rmiexample;
import java.rmi.*;
import java.util.*;
import java.io.*;
public class PropertyServer {
private static final String HOST="localhost";
public static void main (String[] args) throws Exception {
 File file = new File("c:\\temp\\property.csv");
 try {
 // Following line use Scanner class to read data file content line-by-line.
 Scanner scanner = new Scanner(file);
 int housecount=0;
 String line = scanner.nextLine();
 while (scanner.hasNextLine()) {
 int count=0;
 // From the above line of code we got a line from the file
 // content. I am spliting the line using '%' as the delimiting
 // character. Comma not used as it can be included
 // in the address of a property
 String[] houseDetail = line.split("%");
 String location=houseDetail[0];
 String hsePrice=houseDetail[1];
 String bedroom=houseDetail[2];
 String houseType=houseDetail[3];
 String address=houseDetail[4];
 String agency=houseDetail[5];
 //Converting the price and # of beds to Integer.
 double price;
 int beds;
 beds=Integer.parseInt(bedroom);
 price=Integer.parseInt(hsePrice);
 PropertyDetails[] propertyList = {
 new PropertyDetails(location,beds,houseType,price)};
 //I think thisis were I have my problem is....
 Vector<PropertyDetails> propDetail = new Vector<PropertyDetails>();
 propDetail.add(propertyList[count]);
 System.out.println(propertyList[count]);
 PropertyImpl temp = new PropertyImpl(propDetail);
 String rmiObjectName = "rmi://" + HOST + "/PropertyDetails";
 Naming.rebind(rmiObjectName, temp);
 count++;
 line = scanner.nextLine();
 }System.out.println("Binding Complete!!");
catch (FileNotFoundException e) {
 e.printStackTrace();
}

Take a look at: http://java.sun.com/j2se/1.3/docs/guide/rmi/getstart.doc.html
You need start by declaring an interface that extends Remote.

Read different language from the file and upload data

Hi Expert,
I am loading customer master data through BDC( trx-XD01) by reading a file from PC. The file contains customer data in different language like English, Chinese, and Japanese etc. However, when creating customer master data, only those data in English are able to create, as I am in English log on. The data in other language is showing garbage value. However, when I am logging in with that language (say Chinese) this time I am able to create customer for Chinese data but not for other.
Can someone one help me to solve this problem irrespective of language in the file and SAP log on, I should able create customer through my program.
Thnx ,
Deba

I want to list all the files that has the entry with 33..for ex..file with name amg-9876544-M37607-3300259.PDF after the -.
If I give ls -rlt | grep *33* it lists all the file with entry 33 anywhere in it.I want to grep for files with 33 after that "-" in the file name..
Please suggest
Kai

If the only "-33" is the one you are interested in:
ls -rtl | grep -e -33The "-e" prevents grep(1), et. al., from thinking that "-33" is a command line
switch.

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 = ''.

How to Extract particular field from a string ( Mapping)

how to exteract the particular field from the given string:
ProcessEmp this element has a below string subfields.
<ProcessEmp><?xml version="1.0" encoding="utf-8" standalone="no"?>
<Employee PersonnelNumber="11111" FirstName="String" MiddleName="String" LastName="String" Department="String" Group="" SapUserID="10flname" EmailAddress="[email protected]" DefaultPassword="*" Status="Success" /></ProcessEmp>
how to extract only PersonalNumber, department, EmailAddress from above ProcessEmp into 3 diff fields.
Thanks
dhanush.

Hi,
You are receiving XML message within a field. To access a particular field from that XML message, you could create a User Defined Function, as suggested by many already.
You could write UDF using some of the String operation functions. This could include following:
1. If you need to access field Employee PersonnelNumber, you could get last index of that within string using function lastIndexOf(String str). Pass string "Employee PersonnelNumber="" for this function.
2. This function would return an index of rightmost occurance of this string.
3. after this you could get the index of next occurance of ", as the value of field is within quotes. You could use function indexOf(int ch, int fromIndex) for getting the same. You would pass Character as " and index as the one received by previous function.
4. Now you have index for starting and ending point of value string for desired field.
5. After this you could use substring(int beginIndex, int endIndex) function by passing first and second index values to retrieve the needed string, which contains value of field.
Hope this would be helful.
Thanks,
Bhavish

Hi!
This is a possible solution to your problem.

 public static void main(String args[]) throws IOException{
 //retrieve the commandline parameters
 String fileName = "default.html";
 if (args.length != 0) fileName =args[0];

 System.exit(0);
 BufferedReader in = new BufferedReader(new FileReader(new File(fileName)));

 while (st.ttype != StreamTokenizer.TT_EOF) {
 i = st.nextToken();
 if (st.ttype == StreamTokenizer.TT_WORD) {
 if (st.sval.equals("href")) {
 i = st.nextToken(); //the next token (assumed) is the '=' sign
 i = st.nextToken(); //then after it is the href value.
 getURL(st.sval); //retrieve address
 in.close();
 static void getURL(String s) {
 //Check string if it has http:// and truncate if it does
 if (s.indexOf("http://") > -1) {
 s = s.substring(s.indexOf("http://") + 7, s.length());
 //check if not mailto: do not print otherwise
 if (s.indexOf("mailto:") != -1) return;
 //printout anything after http:// and the next '/'
 //if no '/' then print all
 if (s.indexOf('/') > -1) {
 System.out.println(s.substring(0, s.indexOf('/')));
 } else System.out.println(s);
}Hope this helps. I used static methods instead of encapsulating everyting into a class.
