How to use ABAP Class to modify Web Query Result ??

Hi all !
We are using Web Templates to display our Query.
What I would like to do ( and seems a really important issue for our users! ) is to have a "PAGE BREAK" everytime the value of a charateristics change in the report
For Example :
-Page 1-
Division     Project
   A               1
                    2
                    3
-Page 2-
Division     Project
   B               1
                    2
                    3
and so on....
I read threads about using ABAP CLASS but no example what so ever...
We are presently under BW 3.1 but are considering upgrading to 7.0 by the end of the year so if there is a solution to my problem on either version i'd like to know.
If anyone has any information about how I can do this it would be most appreciated
Thx
JB.

Hi Yong,
Ravi is right, first check the blogs by Jocelyn, and if you still have specific questions you can ask them. I have used ABAP classes in workflow and I know Mike Pokraka tries to use classes exclusively.

Martin

How to use abap memory in global class

Hi experts,
I want to know how to use abap memory in global class. when i try write export and import statement its showing
error is export statement does not support in object oriented concept.
Thanks

Hi Ramesh,
Export and import statements were not allowed to use in classes. Create a global variable in public section of that class of type of export parameter.Then pass value to the global variable of class by calling that class.

Using a class in a web module

I'm using netbeans and the web module template.
I'm pretty new to jsp, so please bare with me. I just want to be able to use a class in my jsp page.
I have 2 files:
WEB-INF/classes/Customer
index.jsp
in the Customer Class, i declare the package at the top:
package com.mycompany.data
public Class Customer {
in index.jsp, I want to use the Customer Class. I try like this:
<%@ page import="com.mycompany.data.*" %>
<%
Customer cust = new Customer();
%>
I keep getting an error in index.jsp on both the page directive and on the line where I declare and instantiate the Customer object.
Can someone inform me or point me to the right place to understand how to use a class in a .jsp?
Thanks

If the class Customer is in package com.mycompany.data
Then Customer.class should be a file in
web-inf/classes/com/mycompany/data/Customer.class
Apart from that it looks ok.
You might consider using a <jsp:useBean> tag instead of declaring customer in a scriptlet.
I'm very much a fan of minimum scriptlet code on a page.
Cheers,
evnafets

Enable ABAP Class in 7x Web Template

Hi All,
We are upgrading Web Templates from 3x to 7x and we need inputs for amending Custom ABAP Class in 7x web templates. In existing 3x version there are couple of web templates which concatenate columns based on custom abap class, this option is enabled via Results_Table > Table Interface Class > Custom Class is called. But when it comes to 7x version how do we acheive enabling the custom class.
I have tried Custom Extension from Miscellaneous and enabled the Custom ABAP class but the query fails upon execution
Thanks

Hide a specific cell using ABAP classes

Hello Thomas Daly
    I never saw a way to grant permission to a List, the only way I ever saw a list get its permissions is thru
the group site it resides in, the Discussion Board is the problem in this case (it has preconfigure permissions but they seem more like properties that you select the value from RadioButtons). However, ms-addnew gets rid of the Add new link but it
gets rid of the one in the Discusson Board too because Discussion Board falls in the category of List.
    In other words ms-addnew in the master got rid of all of the Add new items, link etc as hoped but now
I can't add to the Discussion Board.
    I am alright with a hack (I am open to any suggestions) that would work if it works but, the List's I am referring to are all "Links" in the Quick Launch so I dont know how you would be able to apply the jquery, how would you apply the
jquery to a Links in a Quick Launch?
    Thank you

Create Navigation path in IDT4.0 and how to use these navigation paths in Webi report

Hi All, I want to know how to create navigation path in universe? I am using IDT BO4.0 SP4 and relational connection and want to create navigation path. I would like to know how to use this navigation path in Webi report? If I create a webi report where can I see my navigation paths and how to use it. If you can give any document or link which expalins this whole process, that would be great. Thanks,

HI REMI ,
1. ANSWER TO YOUR 1st QUESTION i.e. HOW TO CREATE A NAVIGATIONAL PATH :
    IN IDT 4.0 , YOU WILL FIND A NAVIGATIONAL PATH IN BOTTOM WHEN YOU WILL OPEN YOUR      BUSINESS LAYER , THERE YOU CAN CLICK CUSTOM NAVIGATION PATH -> THEN CLICK AT      ADD A NAVIGATIOAL PATH BUTTON->THEN GIVE NAME NAVIGATIONAL PATH NAME->THEN ADD THE OBJECTS UNDER YOUR NAVIGATIONAL PATH IN A HIERARCHICAL SEQUENCE .     FOR EX :     COUNTRY->STATE->CITY . AND YOUR CUSTOM NAVIGATIONAL PATH IS     CREATED.
2. ANSWER TO YOUR SECOND QUESTION WHAT IS THE USE OF NAVIGATIONAL PATH IN WEBI REPORT :
NAVIGATIONAL PATH HELPS YOU TO PERFORM DRILL DOWN ON YOUR DIMENSION OBJECTS , FOR EX : LET 'S SAY YOU CREATED A NAVIGATIONAL PATH- REGION SALES : Containing COUNTRY->STATE->SALES. THIS WILL HELP YOU TO DRILL DOWN IN YOUR WEBI REPORT AS SHOWN BELOW :
COUNTRY                      SALES
INDIA                             $1000000
(after clicking INDIA you will get below structure in your Report)

How to use create by and modified by

how to use create by and modified by ?
when some one create row it will stamp who create
and when some one edite row it will stamp who edit row
i ever user create on and modified on
but creay by and modified by i never use it.

Howard,
If you are not using JAZN you can still register created by and modified by user and date info in a "backdoor-wise" way:
1. Get the user login string by using System.getProperty("user.name")
2. Get the current datetime using java.util.Date
3. In the backing bean for the page and the action method for your submit button, set the values for the components containing the created by or updated by values to the values obtained in points 1 and 2.
Hope this is somehow useful,
AG

How to use TableSorter class with DefaultTableModel

Thank you for your service
Cheers
Jofin

I don't know about any TableSorter class, but I suppose you mean javax.swing.table.TableRowSorter.
The TableRowSorter is to be attached to the JTable, not to the data model. Here's a cut'n'paste from the last time I used it:
RowSorter<TableModel> sorter = new TableRowSorter<TableModel>(tableModel);
myTable.setRowSorter(sorter);
And heres from the JDK1.6 documentation:
TableModel myModel = createMyTableModel();
JTable table = new JTable(myModel);
table.setRowSorter(new TableRowSorter(myModel));
Check out http://java.sun.com/javase/6/docs/api/javax/swing/table/TableRowSorter.html. I find it to be good documentation.

Function module equivalent to SWE_EVENT_CREATE while using ABAP classes

Hi there,
I used to use SWE_CREATE_EVENT to fire the events linked to my BOR objects, in order to start certain workflows.
Now I am using ABAP classes within the WorkFlows, and the name of the classes MUST (in my case) be longer than 10 characters, and SWE_EVENT_CREATE is cutting the name so it does not work
Do you know any FM equivalent to start an event from a ABAP class (SE24) object?
I have tried to use SAP_WAPI_START_WORKFLOW, but I cannot find the way to include my object in the container. Any ideas on this point would be welcome as well
Thanks so much,
Miguel

Thanks for such a quick reply,
You were right. I actually did follow Jocelyn's blogs, but somehow I skipped the raising event section.
Just for information, the URL with the solution to this problem is:
/people/jocelyn.dart/blog/2006/07/27/raising-abap-oo-events-for-workflow
Have a good one

How to use multiple classes for each form

Hi,
I have created two forms using screen painter and now i want to use different classes for these two forms .
I have declared the Sbo Connection in main class i.e. Set Application ,Connection Context() but while connecting to other classes
for executing the code for that form SAP is not connected to that class.How to use multiple classes functionality i don't able to
do that.Please provide some sample codes for that as it will be more helpful for me to understand.
Thanks & Regards,
Amit

Hi Amit,
In fact, its more advisable to use separate classes for every form that you use. Have one common class, say, for eg., clsMain.cs which has all the connection and connectivity to other classes, wherein, the menu event and item event of this main class, will just be calling the menu / item event of other classes.
The individual functionality of the child classes will be called from the item / menu event of the respective classes.
Item event in clsMain.cs will be as below.
private void oApplication_ItemEvent(string FormUID, ref SAPbouiCOM.ItemEvent pVal, out bool BubbleEvent)
            SAPbouiCOM.Form oForm;
            BubbleEvent = true;
            try
                if ((pVal.FormTypeEx == "My_Form1Type") && (pVal.EventType != SAPbouiCOM.BoEventTypes.et_FORM_UNLOAD))
                    oForm = oApplication.Forms.GetForm("My_FormType", pVal.FormTypeCount);
                    NameSpace.Repots.ClsForm1.ClsForm1_ItemEvent(oApplication, oCompany, oForm, ref pVal, ref BubbleEvent);
                if ((pVal.FormTypeEx == "My_Form2Type") && (pVal.EventType != SAPbouiCOM.BoEventTypes.et_FORM_UNLOAD))
                    oForm = oApplication.Forms.GetForm("My_FormType", pVal.FormTypeCount);
                    NameSpace.Repots.ClsForm1.ClsForm2_ItemEvent(oApplication, oCompany, oForm, ref pVal, ref BubbleEvent);
Now, in the individual classes, you can have their respective item events, which will be called from the main class, and the respective functionalities will occur.
Hope this helps.
