HELP bout EXTENSIONIN in BAPI_PO_CHANGE

I want to use 'BAPI_PO_CHANGE' to update PO items by passing EXTENSIONIN in unicode system ECC6.0. I have update the structure of BAPI_TE_MEPOITEMX and CI_EKPODBX.
Here's my code, no error, but the value didn't change.Is anything wrong with my code?
Thanks.

it_extensionin TYPE STANDARD TABLE OF BAPIPAREX,
wa_extensionin TYPE BAPIPAREX,

BAPI_TE_MEPOITEM-ZZ_COMM_STO_NUM = '111'.
wa_extensionin-structure = 'BAPI_TE_MEPOITEM'.
wa_extensionin-valuepart1(5) = '00010'.
*that's the value i want to update

Hi..
I am not sure if you have missed something in the extension structure.... what you can do is check by trial and error method by passing values to other fields also.. many times it so happens that you may need to pass values to some particular fields to update values of some other field....

Need Help'bout Sort with Comparator!!

First of all, the object that Im using is named as "Node". This object has String name, int Value and some kinda things.
In the code below, I made one demantion object array ( Node[]) and filled it with unordered objects. And now I want to sort it by "int Value". There is a function "getVal()" which returns int Value.
Node[] arrlist = new Node[size];
Collect(current, arrlist); <-- this one collects unordered objects
java.util.Collections.sort(arrlist, new Comp());
and the class Comp is below
import java.util.*;
class Comp implements Comparator {
     public int compare(Object o, Object p){
          int answer = 0;
          if (o == p) {
               return 0;
          int node1 = ((Node)o).getVal();
          int node2 = ((Node)p).getVal();
          return node1 - node2;
I dont know much about the comparator. I dont even know what to return in thecomparator class. please help me guys!

You are on the right track. In the compartor, you have to return a negative value, 0 or a possitive value depending on the two values you compare..
some thing like this
public int compare(Object o, Object p){
//.... your codes here
int node1 = ((Node)o).getVal();
int node2 = ((Node)p).getVal();
if( node1 < node2 )
return -1
else
if( node1 > node2 )
return 1;
else
return 0;

Need Some Help Bout Burning Cd's

Hi everyone!!!
In my computer class, myself and a teacher, had a debate over some copyright laws. Let's say I buy some songs off of Itunes. Then I burn them onto a CD and give them to my friend. Then my friend imports the music onto their computer and even adds the music to their ipod. IS that illegal?? Or are we stealing music? I told my teacher that Itunes allows that, but my teacher disagrees. I'm pretty sure they do, for a few different reasons. For one, obviously Itunes is a very complicated and smart system. If they considered that stealing music, then they could probably prevent that from happening in one way or another. For instance, not allowing the music to play on the computer, or just skipping over the song, if its added onto an ipod. But we havent had those problems. So please please please respond, as soon as possible. Thank you!!!

That's illegal indeed. Your teacher is right, iTunes doesn't allow that.
The iTunes Store - Terms of Service tells you all about what's allowed and what not.
One of those rules:
"You shall be entitled to export, burn (if applicable) or copy Products solely for personal, noncommercial use. You shall not be entitled to burn Video Products."
Giving them away clearly violates this rule.
Printing the Terms of Service and discussing them in the classroom might be a good idea

For this bapi in the documentation tab there are no axulliray structures given as i early worked with bapi_po_create1 where they provided the structure names in the bapi documentation based on that i filled all the necessary data.
If you can send to some sample code it would be highly appreciate.
Thanks.

I'm sorry..Maybe my words it not that clear enough. You were right about how ROW_NUMBER works (it
assigns a numeric value and resets based on the grouping you specify in the PARTITION clause).
What I want actually is the row number increment based on the txn_date,poc_code and machine_no.
I'm not sure whether using the row_number() can solve my solutions. I really hope that you could help me.
I thought of using row_number() may help. Do you have any other solution?
Here is my table description.

[HELP] ExtensionIn ---- BAPI_CATIMESHEETMGR_INSERT

Hi All,
Kindly please help me on BAPI_CATIMESHEETMGR_INSERT. I already inserted my custom field COUNTRY to Table CATSDB. I would like to post my entries with my inserted field COUNTRY. I already read the BAPI manual :
ExtensionIn
Customer enhancement import
Description
If you defined additional customer fields in your external application or external system as well as in the SAP System and you want to transfer data from them to the SAP System, you can use this import table. The additional customer fields are reproduced in the customer-specific fields in the CATSDB table using the BAPI_TE_CATSDB structure.
You should enter the name of the structure in the STRUCTURE field. The contents of the BAPI_TE_CATSDB structure is contained in the data part. The data part of this table must be structured analogously to the BAPI_TE_CATSDB structure. The first 10 characters of the data part are for the line numbers. The customer fields are linked to the corresponding data record in the CATSRECORDS_IN table using the line numbers.
>>What are the first 10 characters that I should input? Please. Please help me on this.
Thanks.

Well this is what I think on this.
You have to pass name of the table (say t1) of type BAPI_TE_CATSDB to the Structure EXTENSIONIN
so now t1 will contain the data which will obviously have the corresponding Extension data for the main table CATSDB. But there has to be some way to identify which row of CATSRECORDS_IN matches to row of BAPI_TE_CATSDB record. The first 10 char are supposed to do this linking.
