To get reference value from other dimension

Hello,
Database: Oracle
BO : BOXIr3
Have 2 questions:
1. I want to subtract 2 values for a dimension based on dates like for mindate and maxdate i.e. (the value of dimension for mindate - the value of dimension on maxdate).
Is it possible in WI?
2. I want to get the count of a column.
I drag 2 columns from Universe to report, 1st one is datetime column and 2nd one is a column for which I want count.
Now in custom sql, if want to write one more column for get the count, getting error like" use 3 columns instead 2"
I added COUNT(SITE_ID)
Please suggest.
Thanks & Regards,
Vijesh Chandra

1. I want to subtract 2 values for a dimension based on dates like for mindate and maxdate i.e. (the value of dimension for mindate - the value of dimension on maxdate).

---> Create a variable for your maxdate, however you need to know the level grouping for you Maxdate and you have to use Calculation context. Your variable should have someting like
                              max( [dimentdate] ) in Report
        the In Report tells the WebI to get the max data value of the dimension for the enire report or you may say your max date for the entire query
2. I want to get the count of a column.
I drag 2 columns from Universe to report, 1st one is datetime column and 2nd one is a column for which I want count.
Now in custom sql, if want to write one more column for get the count, getting error like" use 3 columns instead 2"
I added COUNT(SITE_ID)
--> if you want to add another column from your query make sure it has a placeholder. if you have 2 objects in the query and you want to add 3 object with count(siteID), you need to add another object to make 3 and modify the SQL and assign your count to the 3rd column.

Hi Ada,
According to your description, you can't get the member when using the strtomember() function in your MDX. Right?
In Analysis Services, while the member name string provided contains a valid MDX member expression that resolves to a qualified member name, the CONSTRAINED flag requires qualified or unqualified member names in the member name string. Please check if the
variable is a Multidimensional Expressions (MDX)–formatted string.

StrToMember (MDX)
If you have any question, please feel free to ask.

NullPointerException - Cannot get the value from variable f_cashGiven

In SubCheckout.java (a POS), what I want is when Payment button (f_cashPayment) is pressed, the action "Cash" is performed, get the value from Cash Given (f_cashGiven), do the subtraction and post the value as Cash Return (f_cashReturn). The code is filled in actionPerformed. But I cannot get the value by using f_cashGiven.getValue() from VNumber class. It returns NULL. This should be quite straight forward, but I do not know what is wrong. Please help!
Enclosed please find the source code of SubCheckout.java and VNumber.java

If getValue() returns null, you need to trace the execution of the code and figure out which sequence of code is leading to the return of null. This method looks complex - a lot of if statements. If you do not have a debugger, put System.out.println statements inside the method to figure out what's going on.

Swing: when trying to get the values from a JTable inside an event handler

Hi,
I am trying to write a graphical interface to compute the Gauss Elimination procedure for solving linear systems. The class for computing the output of a linear system already works fine on console mode, but I am fighting a little bit to make it work with Swing.
I put two buttons (plus labels) and a JTextField . The buttons have the following role:
One of them gets the value from the JTextField and it will be used to the system dimension. The other should compute the solution. I also added a JTable so that the user can type the values in the screen.
So whenever the user hits the button Dimensiona the program should retrieve the values from the table cells and pass them to a 2D Array. However, the program throws a NullPointerException when I try to
do it. I have put the code for copying this Matrix inside a method and I call it from the inner class event handler.
I would thank you very much for the help.

for (int j = 0 ; j < n ; j++ ){
Object temp1 = model.getValueAt(i,j);
String temp2 = String.valueOf(temp1);
A[i][j] = Double.parseDouble(temp2);

What I did is set up a :
// This code will setup a listener for the table to handle a selection
players.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
ListSelectionModel rowSM = players.getSelectionModel();
rowSM.addListSelectionListener(new Delete_Player_row_Selection(this));
//Class will take the event and call a method inside the Delete_Player object.
class Delete_Player_row_Selection
implements javax.swing.event.ListSelectionListener
Delete_Player adaptee;
Delete_Player_row_Selection (Delete_Player temp)
adaptee = temp;
public void valueChanged (ListSelectionEvent listSelectionEvent)
adaptee.row_Selection(listSelectionEvent);
in the row_Selection function
if(ex.getValueIsAdjusting()) //To remove double selection
return;
ListSelectionModel lsm = (ListSelectionModel) ex.getSource();
if(lsm.isSelectionEmpty())
System.out.println("EMtpy");
else
int selected_row = lsm.getMinSelectionIndex();
ResultSetTableModel model = (ResultSetTableModel) players.getModel();
String name = (String) model.getValueAt(selected_row, 1);
Integer id = (Integer) model.getValueAt(selected_row, 3);
This is how I got info out of a table when the user selected it

How to get the value from databank

Hi,
How to get the value from databank? and how to set the same value to visual script object?
thanks,
ra

Hi,
You can use GetDatabankValue(HeaderName, Value) to get the value from databank and SetDataBankValue(HeaderName, Value) to set the value to databank.
You can refer to the API Reference to see list of associated functions and techniques we can use with related to Data Bank.
This is the for OFT but if you are using Open Script then you have direct access for getting the databank value but when it comes to setting a value you have to use File operation and write you own methods to do the set operation.
Thanks

How to get a value from the previous element (XSLT/XPATH gurus ahoy!)

Hi All,
I am building an RTF template for a "letter of reference"-report. Sometimes there are several rows in the data, that need to be printed as one. This is due to consecutive temporary contracts, which will be printed out as one period of service.
Here's a simplified data example to illustrate the problem.
<ROW>
<START_DATE>01-01-1980</START_DATE>
<END_DATE>01-01-1988</END_DATE>
</ROW>
<ROW>
<START_DATE>01-01-1988</START_DATE>
<END_DATE>01-01-1990</END_DATE>
</ROW>
<ROW>
<START_DATE>01-01-2000</START_DATE>
<END_DATE>01-01-2005</END_DATE>
</ROW>
With the data above, I should print two lines:
01-01-1980 - 01-01-1990
01-01-2000 - 01-01-2005
I need to compare START_DATE of an element (except for the first one) with the END_DATE of the previous element, to find out whether to print the END_DATE for that element or not. How can I get that value from the previous element?
Thanks & Regards, Matilda

use this to get the following End_date
<?following-sibling::../END_DATE?>
Try this
<?for-each:/ROOT/ROW?>
==================
Current StartDate <?START_DATE?>
Current End Date <?END_DATE?>
Next Start Date <?following-sibling::ROW/END_DATE?>
Previous End Date <?preceding-sibling::ROW[1]/END_DATE?>
================
<?end for-each?>
o/p
==================
Current StartDate 01-01-1980
Current End Date 01-01-1988
Next Start Date 01-01-1990
Previous End Date
================
==================
Current StartDate 01-01-1988
Current End Date 01-01-1990
Next Start Date 01-01-2005
Previous End Date 01-01-1988
================
==================
Current StartDate 01-01-2000
Current End Date 01-01-2005
Next Start Date
Previous End Date 01

How to get RGB value from pixel of an image.

hi, i need a little help... Is there any EASY way to get RGB value from point of an image? I searched javadoc but i only found very complex getRGB method working only with regions, and saving data into arrays.
Is there any other way that can use for example image.getGraphics() (so, i mean to get RGB from point of Graphics object) ?
Btw.: If you know, how Sprite.collidesWith(Sprite s, Boolean pixellevel) is working (with pixellevel = true), please write me. It could solve my problem too.
Thanks

Is there any other way that can use for example image.getGraphics() (so, i mean to get RGB from point of Graphics object) ?You can think of the graphics object like a pencil or paintbrush. Does a paintbrush know the color of the surface it is painting on? No.
Btw.: If you know, how Sprite.collidesWith(Sprite s, Boolean pixellevel) is working (with pixellevel = true), please write me. It could solve my problem too.Download the reference implementation from this site and see for yourself.
luck, db

Dvt:pivotFilterBar - how to get selected values from filter

Hi all,
I have a question: how to programmatically get selected values from pivot table's filter bar?
I have tried to use
pivotTable.getDataModel().getDataAccess().getValueQDR(startRow, startCol, DataAccess.QDR_WITH_PAGE);but for page edge dimensions it returns BAD DATA, it seems that it returns some cached values.
Environment: JDev 11.1.1.3.0 without any patches.
thanks,
Miroslaw

Hi,
You can retrieve the selected value in the PivotFilterBar through the model of PivotFilterBar, instead of dataaccess:
// get the model from the pivot filter bar instance
QueryDescriptior queryDescriptor = (QueryDescriptor)pivotFilterBar.getValue();
// retrieve a list of criterion, each one is used to populate each lov within the pivot filter bar

How to get the values from popup window to mainwindow

HI all,
   I want to get the details from popup window.
      i have three input fields and one search button in my main window. when i click search button it should display popup window.whenever i click on selected row of the popup window table ,values should be visible in my main window input fields.(normal tables)
   now i am able to display popup window with values.How to get the values from popup window now.
   I can anybody explain me clearly.
Thanks&Regards
kranthi

Hi Kranthi,
Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

How to get multiple values from the list

I've a list of an item which I queried it from the database. I also created a button that will takes a selected items from the list when it was clicked. I used javabean to get the data from database.
<%     // clicked on Select District Button
Vector vselectedDistrict = new Vector();
Vector vdistrictID = new Vector();
String tmpSelectDistrict = "";
tmpSelectDistrict = request.getParameter("bSelectDistrict");
if(tmpSelectDistrict != null)
     // get multiple values from the list
     String[] selectedDistrict = request.getParameterValues("usrTDistrict");
     vselectedDistrict.clear();
     vdistrictID.clear();
     if((selectedDistrict != null) && (selectedDistrict.length != 0))
                       for(int i=0;i<selectedDistrict.length;i++)
               vselectedDistrict.addElement(selectedDistrict);
          vdistrictID = dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
          for(int i=0;i<vdistrictID.size();i++)
               out.println("district = " + selectedDistrict[i]);                         out.println("district ID= " + vdistrictID.get(i).toString());
%>
// get vdistrict from the database here......
<select name="usrTDistrict" size="5" multiple>
<%     for(int i = 0; i< vdistrict.size(); i++)
%>
     <option value="<%=vdistrict.get(i).toString()%>"><%=vdistrict.get(i).toString()%></option>
<%
%>
</select>
<input type="submit" name="bSelectDistrict" value="Select District">
Lets say the item that i selected from the list is 'Xplace' and I clicked on the Select District button,
what I got is this error message:
org.apache.jasper.JasperException: Unable to convert string 'Xplace' to class java.util.Vector for attribute usrTDistrict: java.lang.IllegalArgumentException: Property Editor not registered with the PropertyEditorManager
So where is going wrong and what the message means?. Any help very much appreciated. Thanks

These are just guesses that might hopefully steer you in directions you haven't looked in yet.
I presume you used triangle brackets (< >) to avoid having the Jive Forum think it was the "italics" tag?
Are you certain this: dbaseInfo.getcurrentDistrictID(nstate,vselectedDistrict);
expects a Vector as its second parameter? And returns a Vector?
I don't believe you've shown how you use the javabean, or its code? Perhaps it should be rewritten to accept an array of strings instead of a Vector?

How can i get all values from jtable with out selecting?

i have one input table and two output tables (name it as output1, output2). Selected rows from input table are displayed in output1 table. The data in output1 table is temporary(means the dat wont store in database just for display purpose).
Actually what i want is how can i get all values from output1 table to output2 table with out selecting the data in output1 table?
thanks in advance.
raja

You could set the table's data model to be the same:
output2.setModel( output1.getModel() );

Getting the Values from a Tiled View

Hi,
I have a TiledView and I have checkbox in the tiled view. I am trying
to get the values of the checked boxes.
I have coded like this.
Object[] links = getRSystemLinks().getCbSystemUrl().getValues();
if I see the links.length i get only one. In html If I see the code
it appends the TileIndex in brackets. If I replace the TileIndex with
0 in all the fields in endCbSystemUrl method I get the correct values.
In the TiledView beginDisplay() method my code is like this.
if (getPrimaryModel() == null) throw new ModelControlException
("Primary model is null");
super.beginDisplay();
resetTileIndex();
pgCustomizeLinksViewBean parentBean = (pgCustomizeLinksViewBean)
getParent();
((DatasetModel) getDefaultModel()).setSize
(parentBean.SystemChoicesValue.size());
Any Suggestions on this.
Thanks
Namburi

Namburi--
Remember, the getValues() method does not return the values from a column in
a TiledView. It is strictly for use by fields that can have multiple
values, like multi-select list boxes.
DO NOT remove the indexing feature from the field names, especially in the
case of checkboxes, because checkboxes aren't submitted back to the server
unless they are checked. By overriding the automatic checkbox tracking
feature JATO provides, you won't be able to tell which checkboxes were
actually checked by row--you'll simply get back a list the same size as the
number of checkboxes that were checked, without any placeholders for the
ones that weren't checked.
Instead, on submit, you simply need to move through the tiledView and check
the value of checkbox on each row:
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
You can use the same construct to build up an array or list:
List checkedList=new LinkedList();
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
checkedList.add(new Boolean(true))
else
checkedList.add(new Boolean(false))
