How to show the columns dynamically in OBIEE report based on the selection?

Hi,
I have a requirement where the columns should be dynamically shown in report based on what we select in propmt page.
I'm creating a report in OBIEE where i want to give an option to the end user to select the columns whichever he wants to see in the report.
For example I have the following columns in the report already:
Customer Name,
Customer Number,
Bank Account,
Address
I want to give an option to the user to select 'Customer Mail ID' dynamically and see the column to be displyed in the report along with the existing columns.
Through 'Column Selector' user can select a single column at a time, but if he want to select more than one column, how can we do this ?
Please help me out in resolving this issue.
Thanks,
Chaithanya.

Hi Chaithanya,
there's not a straight solution for this. You can create different analysis containing different number of columns and then directing the user to this analysis using Action Links or you can also use View Selector to switch from one view (analysis) to the other. But it's not going to be very flexible nor dynamic.

Adding the columns dynamically in crystal report

Hi,
I am developing a application using asp.net and crystal report. In a report the column is created dynamically( ie, the report gets input from a sp which returns N no. of columns). Since i dont know the column name and no. of columns at design time i am not able to create the report. If any of you have any idea on adding the columns dynamically please send me the code or the link.
Thanks

Hi Developer life,
According to your description that you want to dynamically increase and decrease the numbers of the columns in the table, right?
As Jason A Long mentioned that we can use the matrix to do this and put the year field in the column group, amount fields(Numric values) in the details, add an filter to filter the data base on this column group, but if
the data in the DB not suitable to add to the matrix directly, you can use the unpivot function to turn the column name of year to a single row and then you can add it in the column group.
If there are too many columns in the column group, it will fit the page size automatically and display the extra columns in the next page.

How to create table columns dynamically ?

Hi All,
I am working on an SSRS report that will show sales in the past 5 years. If the user selected to view sales of past 3 years he will only see 3 columns. so How can I create table columns dynamically at run time and how can I make sure that their dimensions
will adjust to fit the report page size.

How to sort a column directly after data is filled into the grid?

Hello,
I have a unbound field X, which is filled on fly in the RowLoaded2 column. If I click on the column header, I am able to sort the column.
I want to sort the column directly, but all attempts have failed.
I have tried to call in <anchor>_OnUpdate
<anchor>.bcol.Sort( "X", "ASC") but it does not work as long as the property is not mapped to a Segment field of a bdoc. For this test i just created my property X on the Business Objects behind the tablegrid
I have used <tablegridcontrol>.sortCol = 2, but it results into a StackOverflowException even for any other column.
Is there no way to sort the colum in this special kind of situation?
Regards,
Andreas

Hi,
you have to consider that when loading a tile for the first time always rowloaded2 is fired (several times) and afterwards onload. Maybe rowloaded2 again afterwards. So it should work to sort in onload.
But when clicking the <back> button in the menue the order of the fired events might be different!
Do you want to sort by an unbound column which is readonly or is it also editable (see other thread)? In this case things might be much more complicate... Normally another sorting should be done in onsave event but unfortunately you don't save anything as it is unbound...

Wolfhard

}where COLUMN_ALIAS is the alias of the column in the report query and the width measure is whatever you require.

Dynamically change the contents of one combo box based on the other

Hi Forum,
I have a question which might have a possibly simple answer. Well anyway help me out since i could not find the simple answer.
I am building an application using Swing and binding with BC4J using JClient. My GUI has combo boxes, grids, editboxes. My requirement is that i should be able to dynamically change the contents of one combo box based on the selected item in trhe previous combo box. For example, when i choose a country in the "country combo box", the "states combo box" should show the list of the states of the selected country.
Now how do i do this using binding. If not, how do i write custom querirs in BC4J layer and return a resultset to the remote application so theat i can populate the dependent combo boxes.
I will appreciate if anyone can help me out in this regard.
Thank You
Sumit

there could be quite a few number of ways of solving this problem.
One way is through event handlers.
taking your example as a model when user selects a country you could fire an action with a flag set to ture. A method will return the states from the DB or your temporary files or what ever and then the true flag will be used in the states combo box rendering.
other way: javascript
this might be a bit clumsy as you will need the states information in a property file and you can get the info as the user selects a country.

How to create a report based on the selection of a node of a tree

Hello,
I am new to Oracle Apex and I was trying to build a tree and also an interactive report based on the empno column of the emp table.
I have created a tree based on emp table. Now I want to display records of the employee selected in the tree.
Here is the tree query:
select case when connect_by_isleaf = 1 then 0
when level = 1 then 1
else -1
end as status,
level,
"ENAME" as title,
null as icon,
"EMPNO" as value,
null as tooltip,
null as link
from "#OWNER#"."EMP"
start with "MGR" is null
connect by prior "EMPNO" = "MGR"
order siblings by "ENAME"
Can anyone tell me step by step how to go from here?
I tried to follow the thread Re: tree question but could not understand much from it.

The approach for reloading the page and displaying the report is quite simple.
<li>You start by creating a new page item which would be used to store the selected node ID , eg. P100_SELECTED_NODE (you can make it atext item and change it hidden once everything works as expected)
<li>Modify the tree query and change the link column in the tree definition SQL query to a link to the same
for example if your page is 100 , you would make the tree node link to the same page but set the P100SELECTED_NODE with selected node's id_
This done here
{message:id=4410987}
In this case it would be
'f?p=&APP_ID.:100:'||:APP_SESSION||'::::P100_SELECTED_NODE:'||EMPNO as link Now when you click on a tree node link , it would come back to the same page, but set the P100_SELECTED_NODE with the empno of the clicked node.
<li> All that is left to do, is changing your Report so that it refers to the new item inorder to filter the records for this employee i.e empno
SELECT ...
WHERE empno= :P100_SELECTED_NODE

Calling multiple sub-reports based on the values in a column in the main report

All,
Say, I have a main report with 4 parameters and 8 columns in it's tablix, there is 1 column in this main report that can have 3 values, say A,B,C. If the user clicks on "A", he will be directed to Subreport A, clicks on "B", he will be
directed to Subreport B and if he clicks on "C", then he'll be taken to Subreport C. All works fine when I call subreport A and B from that column, because both of them have the 4 parameters that we can map back to the parameters of the main report
in the "Go To Report" section.
Now, for Subreport C, I'll need to map all those 4 parameters + I will also need to map the parameters in my Subreport C to the FIELDS in the main report. Subreport C has 8 parameters, so 4 of them get mapped to the parameters of the main report and
the other 4 get mapped to the fields in the main report.
Now, when I call the Subreport C from my main report, that runs fine, but, I get an error when I try to call my other subreports A and B. The error says "Parameters in the subreport are not defined", probably because it tries to map the fields
in the main report to the non-existing parameters in mu Subreport A and B.
Any ideas/suggestions/workarounds would help a lot. Also, if someone can point me to a link where multiple subreports are being called from the column of a main report would be a great help too.

One simple solution would be to add the additional 4 parameters to subreports A and B. Just don't use them.
I assume you are calling the subrebort using Go to report action property of the tablix cell control. Try switching to Go to URL. Then use expression builder to dynamically create your url:
="http://YourReportServer/Reports/Pages/Reports.aspx?ItemPath=%2fYour%2fReport%2fPath%2fReport"+Fields!Column1.Value+"&Parameter1Name="+Parameters!Param1.Value+"&Parameter2Name="+Parameters!Param2.Value+"&Parameter3Name="+Parameters!Param3.Value+"&Parameter4Name="+Parameters!Param4.Value+IIf(Fields!Column1.Value="C","&Param5="+Fields!F1.Value+""&Param6="+Fields!F2.Value+""&Param7="+Fields!F3.Value+""&Param8="+Fields!F41.Value,"")
Now this is a rather long formula which is why I prefer just adding the other 4 parameters to all of the subreports but this expression opens the report from the url and only when Column1 field is "C" does it also pass the additional 4 parameters.

Re : Issue with the column display in Bex reports

Hello Gurus,
I have an issue with the reports in Bex, this is a bit confusing scenario I would try to explain in more details. A query was already built for monthly Report in Sales and Billing for which the variable were Calender month/year range 1 (mandatory), range 2 range 3 range 4. These 4 variable were created and moved to column rows in query.
Later the user wanted the copy of same report but he wanted the variables to be Calender date range 1 (mandatory), range 2, range 3 , range 4. I have created them with 0calenderday as reference and moved to the columns.
for the monthly report text variables were already existing for the Calender month/ year, but for the daily report text variable were not existing for Dates. I have created a text variable for the date in the following way processing by
" replacement path" and reference characteristic as 0calday and in the replacement path tab.. in replace variable the selection is info object, the next option Replace with " External charactersitic value key " .
By creating this text variable the dates were being displayed in the colum header like 11/01/2013 - 11/30/2013 which satisfies the requirement.
But the user wanted to see the report same like monthly report when the mandatory variable Calender year/ month is selected, the rest of the columns range 2, range 3, range 4 are displayed as unassigned in the report. but coming back to the daily report when the user is giving the Calender date rage 1, he is finding that Calender date range 2, range 3, range 4 are also being displayed with values. He want to see the Calender date range 2,3,4 as unassigned in the report just like monthly. Please find the images attached.
As Calender month/ year is predefined, if the calender range values are not given it would show up as not assigned default. I have created a separate text variable for Calender day, I believe that could be the reason rest of the columns are not showing up as unassigned. The user want to see them as unassigned like monthly report columns.
I tried different ways changing the text variables but I could not change the display of the columns in Calender date report by the option - replace with ----> External characteristic value key, key, label. when I chose the option external characteristic value then the date was showing up in the text of the column when report is run ( Please find the image for the reference in the attachment ). . I request you to help me out in this. Please find the images of the variables and output below.

Anshu,
Thank you very much for above code I made minor changes to the code that finally worked. I created 4 different text variables needed for Calender date range 1, 2 ,3 ,4. Please find the code below for the text variable that worked in the system
WHEN 'ZTEXT_CAL1'.
   READ TABLE I_T_VAR_RANGE INTO loc_var_range
   WITH KEY VNAM = 'ZCALDATE1'.
    IF loc_var_range-LOW = '#'.
      dt_low = 'Not Assigned'.
      dt_high = 'Not Assigned'.
      CONCATENATE dt_low '-' dt_high INTO l_s_range-low.
    ELSE.
      CONCATENATE loc_var_range-low+4(2) '/' loc_var_range-low+6(2) '/' loc_var_range-low+0(4) into dt_low.
      CONCATENATE loc_var_range-high+4(2) '/' loc_var_range-high+6(2) '/' loc_var_range-high+0(4) into dt_high.
      CONCATENATE dt_low '-' dt_high INTO l_s_range-low.
    ENDIF.
        L_S_RANGE-SIGN = 'I'.
        L_S_RANGE-OPT = 'EQ'.
        APPEND L_S_RANGE TO E_T_RANGE.

Other options include using a PL/SQL function returning the string to use as the dynamic query etc.

I have a formula, where I want the columns to remain constant but I want the middle number to increase by 1. How do I do it? =SUMIF($F2:$F45,1,$H2:$H45)
The first cell contains the correct formula with the columns highlighted. Autofill gives me a red triangle. The columns are no longer highlighted.
I have done this in Excel. I will learn Numbers!
Thank you.

Hi,
When posting formulas, as a courtesy, please select the formula in the entry bar, Copy, then Paste the formula into your message. This permits the reader to copy the formula directly from the page, paste it into the reply, and edit it there. When pasted as an image, that reader has to read the formula from the image and type it into the reply, increasing the probability of errors creeping in.
=SUMIF(F2:F10,COLUMNA+1,H2:H10)
The syntax error is in the part shown in bold. Here is the image of the similar formula from my reply above:
With the syntax error corrected, your formula would read:
=SUMIF(F2:F10,COLUMN()+1,H2:H10)
Restated in English, the formula says:
"calculate the SUM of all numbers in cells H2 to H10, where the value in the same row of column F is equal to the column number of this cell plus 3."
In your image, this cell (the cell containing the formula) is C3. That's in column 3, so the value "COLUMN()+3" is 6. Considering the headers in your screen shot, that is probably not what you want to happen.
NOTE: Your original formula (and mine, modeled on that original) used the $ operator to fix the Column values of the cell references, making them stay the same when the formula is filled right. Your description indicates you want to fill the formula down. Unless you attach the $ operator to the Row part of the cell references, the row value will change as the formula is filled down, producing an 'invalid reference' error when the referenced range extends beyond the bottom of the table.
Change the range "$F2:$F45" in your original formula to read "F$2:F$45" (and make a similar change to the range in column H) to keep the range the same when the formula is filled down. You'll also need to use ROW()-n in place of COLUMN-n, as filled down. all copies of the formula will be in the same column.

Barry

Filter the report based on the parent report column values

Hi,
period --- jan12 feb12 mar12...
tickets --- _3_ _10_ _16_ .....
This is my report layout.When i click on the no.of total tickets 3/10/16.It need to navigate to another report which should be filtered based on the reporting period as well as total tickets.
How can i achieve this requirement.Is there any possibility to pass the column values from one report to another report?
I tried "filter based on the another request" but it not worked for me.
The summary of the requirement is when i click on 3 it need to display the 3 tickets details only...
Anyone please help me out.
thanks,
prassu

If your query means that for Jan 12 there are 3 tickets and for Feb 12 there are 10 tickets in the database, then you should only need to make the Period Column Is Prompted in the detail report. If the action link is not working this way then something else is wrong. Is the detail made from the same subject area?
