Dynamic columns in OBIEE

Hello all,
I have a weird requirement.
Report is based on the period date we selected. We pass a Period/Month as parameter, once that is passed we want the data of the previous 4 months.
Say for example, he passed parameter as Feb'10 -- we want data for Nov'09, Dec'09, Jan'10, feb'10 and column labels shuld be dynamically changed as per the parameter...
can we achieve this in OBIEE? If so please tell me how to do that...
Thanks in advance...

Hi Kiran,
you can achieve this.
But only in Pivot table.
Follow this.
Add some column in criteria and Use the following in the column formula.
'<table width="100%" align="center" bordercolor="#C9CBD3"
frame="void" rules="cols" cellpadding="0" cellspacing="0">
<tr>
<td align="center" width = "200">
<font color = "black">'|| _............._ ||'</font>
</td>
<td align="center" width = "200">
<font color = "black">'|| _............._ ||'</font>
</td>
<td align="center" width = "200">
<font color = "black">'|| _............._ ||'</font>
</td>
<td align="center" width = "200">
<font color = "black">'|| _............._ ||'</font></td>
</tr>
</table>'Do not forget to change the Data Format of this column to 'HTML'
Place this column on top of measures labels in Pivot View.
But, you need to fix the width of all the measure columns and adjust the <td> width accordingly.
Now, replace _............._ with the corresponding month names.
(For this u can use some formula to get the last four names here)
Hope it helps. :)
If you find it useful, Please award points.

Dynamic Column Selector in OBIEE - Solution required

Hello Experts,
I am pretty new to OBIEE. Please help me to get OBIEE solution for below requirement.
I have one 25 column dimension table in database. Created OBIEE .rpd file and published in BI server. Now I need to provide one user interface in which user should be able to chose any number of columns of his choice and he should get record set of those selected columns. Something in my mind is like this.
I should be providing list of 25 column names with check box to select one or many. Assuming that if user selects Col1, Col3,Col5 and Col7 then he should get the result in excel file with record set of those 4 columns.
I am using OBIEE 10g.
Any solution for this is highly appreciated.
Edited by: user7850154 on Dec 5, 2010 9:22 AM

user,
Usually, dynamic column seletor is implemented through "column selector view" available within compund layout of OBIEE Answers.
But, it does allow you to select only single column rather than multiple columns - which in your case is required.

Dynamic column name in OBIEE

Hi all,
In my report i need to show one chart view. I'm having one prompt. There the user is asked to select a no. for eg. say 10. and a date eg. 10-JAN-09. So my report should show the data from 10-JAN-09 and go backwards to 10 days. if he selects 5 days then only 5 days of data only need to show from that date. This part is ok. The chart has five sections in it. They are
1) 80-100% of the time period
2) 60-80%
3) 40-60%
4) 20-40%
5) <20%
So the legends should vary according to this.
Suppose if the user selects 10 days then the legend should be,
1) 8-10 days
2) 6-7 days
3) 4-5 days
4) 2-3 days
5) less than 2 days
If user selects 5 means then the legend should be,
1) 5 days
2) 4 days
3) 3 days
4) 2 days
5) 1 day
In the prompt im saving this value in one variable. So all i need to do is to apply aggregation on the variable and place it in the column name. But i dont know where to give it. Please help.
Thanks,
Karthick

Hi when you dynamically change the table column that will automatically reflect in the chart legend.
please check the following link for dynamically changing column header name

its a BI Publisher report.
please suggest

if you have data in db then you can create xml with needed structure
and so you can create bip report
do you have errors or .... ?

How to change recordset bahaviour to accept dynamic column names in the where clause

Hi
im using php-mysql and i make a recordset and i want to make the column names in the where clause to be dynamic like
"select id,name from mytable where $tablename-$myvar";
but when i do this my i break the recordset and it disappear
and when i use variables from advanced recordset it only dynamic for the value of the column not for the column name
and when i write the column name to dynamic as above by hand it truns a red exclamation mark on the server behaviour panel
so i think the only way is to change the recordset behaviour is it? if so How to make it accept dynamic column names?
thanks in advance.

As bregent has already explained to you, customizing the recordset code will result in Dreamweaver no longer recognizing the server behavior. This isn't a problem, but it does mean that you need to lay out your dynamic text with the Bindings panel before making any changes. Once you have changed the recordset code, the Bindings panel will no longer recognize the recordset fields.
Using a variable to choose a column name is quite simple, but you need to take some security measures to ensure that the value passed through the query string isn't attempting SQL injection. An effective way of doing this is to create an array of acceptable column names, and check that the value matches.
// create array of acceptable values
$valid = array('column_name1', 'column_name2', 'column_name3');
// if the query string contains an acceptable column name, use it
if (isset($_GET['colname']) && in_array($_GET['colname'], $valid)) {
$col = $GET['colname'];
} else {
// set a default value if the submitted one was invalid
$col = 'column_name1'
You can then use $col directly in the SQL query.

How to place one column under another column in obiee report?

Hi all,
I am new to obiee, so need some help from obiee experts. Can anyone tell me how to place one column data under another column in obiee report?
i need the report to be as below
category total_students Course_enrollment Test_attended pass_test
total N % N % N %
all students ##### ## ## ## ## ## ##
Ethnicity
Asian ###### ## ## ## ## ## ##
African American ###### ## ## ## ## ## ##
white ######
Filipino ######
Gender
Male ##### ## ## ## ## ## ##
Female ##### ## ## ## ## ## ##
and similarly for other columns
where ethnicity, gender are columns in the table and Course_enrollment, Test_attended, pass_test are calculated columns.
Please help me to create a report as above if anyone knows how to do it.
Edited by: Shailaja on Jul 19, 2010 12:23 AM

Two ideas I can think of:
1) Create multiple pivot tables and then display them one under the other
2) Create multiple measure columns such as "male_amt", "female_amt", "white_amt", "asian_amt", "black_amt", etc. for all the columns you need. Then you could simple stack them in a single pivot table.
Option #2 might give you the prettiest results - but also requires a lot more maintenance (for instance, if you reclassify ethnic groups, you'd have to go through the reports to add additional metric columns).
Hope this helps,
Scott

How to add two columns in OBIEE report?

Hi to All,
Can anyone tell me how to add two columns in OBIEE report and get that result in a new column?
Thanks in Advance,
Thenmozhi

Assume you already have two columns SalesAmt1 and SalesAmt2, and you want to derive 3rd column say SalesAmt3 which would be the sum of SalesAmt1 and SalesAmt2.
For this, as I mentioned above pull SalesAmt1 and SalesAmt2 columns in Report. Now pull another column (say SalesAmt1) and open the fx. Clear the contents of fx. Now locate the columns button in the bottom of the fx. From Here, first select SalesAmt1 and + sign and the select SalesAmt2.
Now in this new column, the fx should look like SalesAmt1 + SalesAmt2.
Let me know if you are looking for something else.
Thanks

Saving result from sp_executesql into a variable and using dynamic column name - getting error "Error converting data type varchar to numeric"

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
>> I need to select from a dynamic column name and save the result in a variable, but seem to be having trouble with the values being fed to sp_executesql <<
This is so very, very wrong! A column is an attribute of an entity. The idea that you are so screwed up that you have no idea if you want
the shoe size, the phone number or something else at run time of this entity.
In Software Engineering we have a principle called cohesion that says a model should do one and only one task, have one and only one entry point, and one and only one exit point.
Hey, on a scale from 1 to 10, what color is your favorite letter of the alphabet? Yes, your mindset is that level of sillyity and absurdity.
Do you know that SQL is a declarative language? This family of languages does not use local variables!
Now think about “month_val” and what it means. A month is a temporal unit of measurement, so this is as silly as saying “liter_val” in your code. Why did you use “sp_” on a procedure? It has special meaning in T-SQL.
Think about how silly this is:
SET @month_val = 'Month' + CAST(@month_nbr AS VARCHAR(2));
We do not do display formatting in a query. This is a violation of at the tiered architecture principle. We have a presentation layer. But more than that, the INTERVAL temporal data type is a {year-month} and never just a month. This is fundamental.
We need to see the DDL so we can re-write this mess. Want to fix it or not?

Removing drag functionality of column in OBIEE 11g

Hi all,
Can any one say me how to remove the draging functionality for the columns in OBIEE 11g ? It is creating an issue for me when i hide the columns in pivot and has only rows over there. It is creating one more layer on the top of the measures.
Thanks for your help.

Fightclub,
Edit the Pivot view and goto Row section -> Row Properties -> Option - Uncheck the Display Heading.
But you'll loose your columns heading of rows.

Dynamic Column in PDF

Hello All,
I have a requirement to generate dynamic column in the PDF.
I have got the same running using the below code
HEADER : <?split-column-header:XXX_TIME?><?split-column-width:@width?><?XXX_TIME_FROM?>
DATA : <?split-column-data:XXX_START?><?EMP_NO?>
The issue I am having is if i generate the output in pdf with small amount of data,it will work but I am not sure how much data can come at run time.
It can be sometime more than 50 or more columns also.In that case it truncates the data.
How can i do the same.
Pls help.
Thanks
Sk

Increase the page size and printable page size, and reduce the column lengths,
so that you can accomadate them in single row.
BIP will run in single row, but we have option of making it to next row too.
But even if you make it in single row, page size has to support the length of the single row you are making :)..
so you got to increase the page width to Max

DataGrid with dynamic columns & renderers

I'm developing using Flash Builder 4 & Flex SDK 4.1.
I need to manage very dynamic DataGrid components and keep their definitions, which are all part of a complex item renderer of an Offers list.
The objects structure is simplified as follows -
Data: Model --> Offers ArrayCollection --> Offer VO --> DataGrid data ArrayCollection & DataGrid columns Array
View: List --> Offer Item Renderer --> DataGrid
1. Since the DataGrid's columns property accepts only an Array (not ArrayCollection), it seems like Data Binding for defining the columns is very problematic.
I tried to bind it to the source property of an ArrayCollection that would keep my columns definitions, but it didn't really work (mainly header display bugs).
What is the recommended way to keep the dynamic columns definition of a DataGrid?
2. Each column can have a set of dynamic properties, so I created a "mutant" - Column VO that extends DataGridColumn and got a dynamic properties ArrayCollection on it.
The columns got a custom header renderer that includes an icon when there are properties.
The header renderers got 4 main states (NotSelectedWithProperties, SelectedWithProperties, NotSelectedWithoutProperties & SelectedWithoutProperties).
However, the header renderer area seems a bit buggy when maintaning dynamic columns.
Any thoughts on the subject?
3. Anyway, I ended up recreating the DataGrid's columns Array very often (copying the columns definition on the offer's item renderer's dataChange event handler).
Note that the dynamic properties can be edited when the column is selected and I copy their values from the view back to the model when entering the state NotSelectedWithProperties.
This feels way too complicated and I really try to keep it simple, inspite of the required complexity.
Does anyone have better ideas?
4. In some cases the column's item renderer should also be modified into another DataGrid (grid-in-grid).
I used the MXDataGridItemRenderer with a DataGrid and included an ArrayCollection for the "newValue" returned by the editor.
(I use RendererIsEditor=true and on updateComplete populate that variable with the DataGrid's dataProvider contents)
When needed, I loop though the data objects of the parent DataGrid and populate the related field with an ArrayCollection of key-value objects that are displayed on the internal DataGrid.
After adding this feature I encounter very strange bugs -
a. After editing the grid-in-grid values and changing the column's state (selecting & deselecting), I get the following exception:
ArgumentError. Error #2025: The supplied DisplayObject must be a child of the caller.
at flash.display::DisplayObjectContainer/setChildIndex()
at mx.core::UIComponent/setChildIndex().......6993....
All I could find about this is that it might be related to some context error or something, but I'm really stuck on this one.
b. Sometimes another column might copy value from one row to another, running over the previous value.
I'm not sure exactly what sequence of actions causes this behavior, but it's related to that itemRenderer for sure.
c. Switching places with a column that uses the grid item renderer (headerShift) causes a stak overflow of StyleManager that tried to get style from the DataGridItemRenderer. This one I just found out, but couldn't reproduce a second time... strange!
I'm pretty sure this caused another problem that I don't remember at the moment.
The bottom line is that there got to be a better way to implement this feature within this already-complicated environment.
Maybe I'm doing something very wrong here...
Please advice and thanks for reading all this.

Update on item 4a -
This was a major issue (the main reason for opening this thread really) and I managed to resolve it!
As part of my application, I override the default DataGrid behavior for column selection (headerRelease event).
Instead of sorting, I change the column's header looks and define it as Selected (for showing its dynamic properties and enable its deletion).
At first I did this by setting styles, but the look didn't refresh unless I created a new instance of the header renderer.
Later I changed thi behavior to work with states, but I left the new header renderer instance creation commands and those lines created all the mess!
Conclusion -
If you define a custom header renderer for your datagrid column and then a custom item renderer, don't create a new instance of your header renderer!
It would still be nice to get some response for the other issues I raised.
Thanks and have a nice week.

Special characters in SBWP dynamic columns are not showing for some users

Hi experts,
We have set up a dynamic columns for business workplace. One of the field displays the comments entered by the user. Some users are able to see the values entered perfectly. But for some users, if we enter special characters like @gopal, it is not displaying the value in dynamic column.
Are there any workflow/user settings need to be changed.
Thanks

I had the same issue, you should check the link between AD and CRM, so you could make a new user in AD and connect your CRM account with it, then you should return the old AD account back. It worked for me, try it :)

Importing From Flat File with Dynamic Columns

HI
I am using ssis 2008,i have folder in which I have Four(4) “.txt” files each file will have 2 columns(ID, NAME). I loaded 4
files in one destination, but today I receive one more “.txt” file here we have 3 columns (ID, NAME, JOB) how can I get a message new column will receive in source. And how can I create in extra column in my destination table dynamically …please help me

Hi Sasidhar,
You need a Script Task to read the names and number of columns in the first row of the flat file each time and store it in a variable, then create a staging table dynamically based on this variable and modify the destination table definition if one ore more
new columns need to be added, and then use the staging table to load the destination table. I am afraid there is no available working script for your scenario, and you need some .NET coding experience to achieve your goal. Here is an example you can refer
to:
