Using presentation variables in report columns

Hi.
I need to create a report column evaluating the difference in days between a field containing a date and a presentation variable.
My field is defined as:
TIMESTAMPDIFF(SQL_TSI_DAY, "Data Scadenza"."Data Scadenza Fattura", @{DataAnalisiScaduto})
Where DataAnalisiScaduto is a presentation variable passed to the report and it's generated on a date field.
Executing the report I get an error and looking at the session manager in the generated query I can see:
TRUNC( (31 / nullif( 12, 0)) / nullif( 2010, 0) ) - TRUNC( T4292.DATA )
Why ? How can I do ?
Thanks,
Andrea

Issue in using presentation variable as filter condition in the reports

Hi,
I have an issue in using presentation variable as filter condition in my reports the details are as follows:
Details :
We want to implement the Max and Min variables through Presentation variables only.we do not want to implement it through session variables in this case.
We have two variables MIN and MAX to be used as Presentation Variables,for a column of the report (which is a quantity),so that the user wants to see the data for this column within a particular range.i.e the Min and the Max.This part has been implemented well . The issue is when the user wants to see the full data.In that case we will not pass any values to these two Presentation Variable or in other words we are not restricting the report data so we are not passing any value to the variables,this is when the report is throwing the error. we want to leave this variables blank in that case.but this is giving error.
Please suggest how can I overcome this issue.
Thanks in Advance.
Regards,
Praveen

i think you have to use guided navigation for this. create two reports first is the one you are having currently and second is the one in which remove the presentation variable from the column formula. i.e. the same report with no aggregation applied.
Now create a dummy report and make it return value only when the presentation variable value is not equal to max or min. guide the report to navigate between the first and second report based on the result of the dummy report.

How to use Value Variable in Report Painter Column defined as Formula

Hi Gurus,
In report painter, how can I add one field (exchange rate) in selection screen, so that user can provide the exchange rate to be used, then execute the report, the exchange rate will used to multiple local currency amount.
The reason for this is we want use provided exchange rate to convert the amount from once currency to the other currency.
Alternatively I am studying the functionality of "Value Variable" and found that I can perform the task from this. I have created the value variable but when I am using the variable in Report Painter columns as "&ZVALVAR", system is giving me error. I read the help and it states that use the variable with "&" and do it as it is mentioned.
Can anybody suggest what I need to do to make it workable.
Thanks

I did try using the presentation variable, but that does not work too. I am setting session variable in the dashboard prompt (select 'request variable'). When I use presentation variable, it hard codes the value of the variable name.
sql is
select date from work_order where facility = @{p_facility}
the physical log sql is
select date from work_order where facility = 'p_facility'

OBIEE 11g: Use presentation variable in Column Heading

Hi everyone,
I was playing around with sample app dashboards and I saw a dashboard prompt that they converted into a column selector. I liked it and reproduced it in my own sandbox.
I like the results, however, I would also like to change the column heading to clearly reflect which measure was selected. It's pretty clear when you are looking in the dashboard, but once you export the data, it can be confusing which measure was selected.
That is why I would like to use a presentation variable in the column heading section. I tried to do this but it interpreted it as a literal instead of evaluating the statement.
Is there anyway to get a variable in the column heading?
Thanks!

Sorting columns dynamically using Presentation Variables

Hi,
I have 4 measures say A,B,C,D , a period dimension and branch name dimension. I would like to select the measure in the prompt and the result should display rank for the selected measure using presentation variables. For eg: If measure-A is selected, the result should be arranged in order by based on "A".
Is it possible to sort the columns dynamically?
Kindly help me.
Regards,
RB

Hi RB,
You can do that, though it's a bit more complicated than a simple SQL statement. For example:
WITH BASEDATA AS (
SELECT
EMPNO,
ENAME,
MGR,
SAL,
COMM,
CASE WHEN :P4_SORT_ORDER = 1 THEN
    ROW_NUMBER() OVER (ORDER BY UPPER(ENAME))
WHEN :P4_SORT_ORDER = 2 THEN
    ROW_NUMBER() OVER (ORDER BY (SELECT NVL(MIN(UPPER(E2.ENAME)),'-Select-') FROM EMP E2 WHERE E2.EMPNO = EMP.MGR))
WHEN :P4_SORT_ORDER = 3 THEN
    ROW_NUMBER() OVER (ORDER BY (SELECT NVL(MIN(UPPER(E2.ENAME)),'-Select-') FROM EMP E2 WHERE E2.EMPNO = EMP.MGR), UPPER(ENAME))
WHEN :P4_SORT_ORDER = 4 THEN
    ROW_NUMBER() OVER (ORDER BY UPPER(ENAME) DESC)
WHEN :P4_SORT_ORDER = 5 THEN
    ROW_NUMBER() OVER (ORDER BY (SELECT NVL(MIN(UPPER(E2.ENAME)),'-Select-') FROM EMP E2 WHERE E2.EMPNO = EMP.MGR) DESC)
WHEN :P4_SORT_ORDER = 6 THEN
    ROW_NUMBER() OVER (ORDER BY (SELECT NVL(MIN(UPPER(E2.ENAME)),'-Select-') FROM EMP E2 WHERE E2.EMPNO = EMP.MGR) DESC, UPPER(ENAME) DESC)
END SORTITEM,
'O' STATUS
FROM
EMP
SELECT
EMPNO,
ENAME,
MGR,
SAL,
COMM
FROM
BASEDATA
ORDER BY
SORTITEMUsing a CASE statement this assigns a ROW_NUMBER to every record based on its ordering within the selected ORDER BY clause. The output is then sorted by this value.

IS there any way to get the date range as 04/01/2012-04/30/2012 instead of comma

How to set MULTIPLE repository variables using presentation variables

Hi,
I need to pass multiple values from presentation variable to repository.
A brief about report design :
I have two repository variables - from_dt and to_dt which are defaulted to some values from a database table and are editable by the user.
I display these default date values on the dashboard. Plus there are two dashboard date prompts allowing user to enter a date range different from what is displayed by the from_dt and to_dt. The dates entered by user are assigned to presentation variables pv_from_dt and pv_to_dt.
If user specifies a different date range then these date values are to be passed to a stored procedure which is called from the Connection Pool --> Connection Script Tab --> Execute before query. This procedure will do some calculations and populate a global temporary table before running the report.
Problem :
Now in the presentation server, in the Advanced tab, in the Prefix section, when i try to write something like this:
SET VARIABLE from_dt = '@{pv_from_dt}';
SET VARIABLE to_dt = '@{pv_to_dt}';
I get the foll error :-
Error Codes: YQCO4T56:OPR4ONWY:U9IM8TAC:OI2DL65P
Odbc driver returned an error (SQLExecDirectW).
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 27002] Near <SET>: Syntax error [nQSError: 26012] . (HY000)
I tried all possible permutations and combinations
SET VARIABLE from_dt = '@{pv_from_dt}',SET VARIABLE to_dt = '@{pv_to_dt}'; --- gave same error
SET VARIABLE from_dt = '@{pv_from_dt}' SET VARIABLE to_dt = '@{pv_to_dt}'; -- gave same error
How do we assign values to multiple reporsitory variables... ???
Thanks
Nusrat

Hi,
I wrongly referred to the variables as "repository" variables. Both variables are Session variables. For testing i added a column field in the report with source as the session variable - VALUEOF(NQ_SESSION.from_dt). In the Prefix section i assigned a literal value - SET VARIABLE from_dt='01-JAN-2012';
When report is run, the literal value gets displayed.
The idea to update a session variable, from dashboard using presentation variable, i got from the following URL.
Go to http://oraclebizint.wordpress.com/category/obi-ee-plus/page/11/
and see the section "Oracle BI EE 10.1.3.3/2 – Updating Session Variables from Dashboards using Presentation Variables"
Thanks

How to pass the values to stored proc using presentation variable in OBIEE

Need your help regarding in resolving an issue in OBIEE 10.1.3.4.1
There are 6 reports say ‘A’,’B’,’C’,’D’,’E’,’F’ in the same subject area.
The reports are being configured with prompts using either the repository/presentation variables.
One of the reports say ‘A’ has been configured to pass the values using presentation variables from the prompt in Advanced Tab of the report request to the stored procedure defined in the Execute Before Query section of the connection pool.
After running another report ‘B’ in the same subject area, upon visiting the report ‘A’ view display error is being seen ( Please have a look below screen shot for your reference) .
Speculate the issue is around presentation variables of report ‘A’ getting initialized even before running the report.
Appreciate your earliest advise as this is a prod issue.

Hi Prasad,
I got your note, you should not use Session variable syntax to call presentation variable.
you should use like @{AIC_PROJ_PLAT_SEQ_NO}
One more thing: first test the variable AIC_PROJ_PLAT_SEQ_NO value then try to pass to SP.
Hope this helps

Unable to pass the values to stored proc using presentation variable in OBI

Hi All,
Need your help regarding in resolving an issue in OBIEE 10.1.3.4.1
There is an OBIEE requirement whereby two prompts need to be defined.
1. Textbox prompt
2. Drop-down prompt
The dropdown values should be populated using textbox prompt. So, we have used presentation variable in textbox prompt and passing the same to select query of drop-down.
Until this step, the report works just fine.
Now, the value in both textbox and drop-down needs to be passed to stored proc.
While trying to pass the values by using the presentation variable, the following error comes-up saying
Session variable has no value definition.
Note:Although the corresponding session variable has been set to default value,still the error appears.
Please advise.
Regards,
Prasad

"Session variable has no value definition" I'm assuming typo error and it should be presentation variable.
Set default value for presentation variable that may work

Using Presentation variables..along with case statements..

Hi All.
I have a issue using presentation variable along with CASE statements. My approach is
1) I have a dashboard prompt, which is being set as Presentation variable.
Based on the value selected in prompt, for ex the values of prompt can be 'ABC' and 'DEF'.
I have a calculated column, the calculation goes this way...
The forumal is
CASE WHEN @{Presentation Variable Name} = 'ABC' THEN xxxxxxxxxx ELSE IF @{Presentation Variable Name} = 'DEF' END. It gives error of "no table being referenced"..
Is this is the right approach??
Can i get the values of variable in a column formula, so that a column can have values selected in prompt?
Can anybody pls help me here..
Thanks in advance...

Hi
Thanks for the quick response..
I agree to ur point..
But the requirement is
Based on the value of the prompt I need to switch the calculation in one of the formula area of one column..
If Prompt value is ABC then one kind of calculation in Fx and If the prompt value is DEF then one kind of calculation in the same Fx..
How can I acheive this?
Thanks in advance..

Unresolved column when using presentation variable in Answers filter

Hi all,
I'm using a dashboard prompt that sets a presentation variable - pres_year. I'm using the presentation variable in a request's filter.
In the 'Criteria' tab, in the filter for the request, I set a year column (YEAR) to the presentation variable via Variable Expr and enter the presentation variable name only. End up with:
YEAR is equal to / is in @{pres_year}
When using the dashboard, the prompt and request all work fine. The problem is when I'm in the request in Answers and I click on 'Display Results' button. I get the following error:
'NQSError: 27005 unresolved column pres_year'
Any suggestions?
Thanks.

I got same error, if i'm using SQL Expression, instead of variable expression in filter section.
make sure that you followed this:
filter on year > Add > Variable > Presentation. Then, give the presentation variable name (which you defined in dashboard prompt) in Variable Expr field , click OK
getting same error when using:
Filter on year column > Add > SQL Expression > presentation variable. This is not right place to give presentation variable.
and, error i got:
*State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 27005]* Unresolved column: "var_Year". (HY000)
so, make sure that you are suing the right one..

Show the presentation variable on table column header

hi, experts,
is it possible to show the presentation variable on the table column header.
I have created a edit box with presentation variable on the prompt.
I would like to show the value the user entered on the column header because the values under that column are driven by the presentation variable.
Thank you very much!

You cannot put variables in the column headers, as they get considered as text and the same shows in the reports.
However, you can use the session or repository variables in the alias field in the presentation layer.
You should make sure, that in this case, all the calculations are done in the BMM layer and not in answers, for the columns where you will be using the variables.

Error using presentation variable in SQL Expression

Hi all,
I'm receiving an error - '...Error getting drill information...' due to a presentation variable being used in a SQL Expression. It probably has something to do with a data type issue. I've narrowed the error to the use of the presentation variable.
I'm setting a presentation variable, pres_mth_nme_to, from a dashboard prompt. The prompt contains a month name.
I'm using the presentation variable as part of a SQL Expression in a filter. The gist of the SQL Expression is to use the
presentation variable in a CASE and set a value accordingly. For example:
Column: Month Sort Value
Operator: Between
Value: *10*
SQL Expression: *Case @{pres_mth_nme_to}{some default} WHEN 'NOV' THEN '10' WHEN 'DEC' THEN '11' WHEN 'JAN' THEN '12' WHEN 'FEB' THEN '13' WHEN...END*
The month name is character. If I were to hard code this, I don't recieve the error. For example:
CASE 'SEP' WHEN 'NOV' THEN '10' WHEN 'DEC' ...END
There something going on with the data type from the prompt and it being used in the comparison. If I use a CAST, the problem still exists.
CASE CAST(@{pres_mth_nme_to} as char(3)) WHEN 'NOV' THEN ... END
If I'm in Answers, the problem doesn't exist, I'm assuming because of the default values. If I'm on the dashboard, it does exist, I'm assuming because of recieving the prompt value.
I don't know what I'm missing. Any suggestions?
Thanks.

DJ,
if the formula presented by you is exactly true, i mean it was not fabricated to present as an example in the forum, you should include the presentation variable in single quotes.
i.e. your formula must look somthing like
Case '@{pres_mth_nme_to}{some default}' WHEN 'NOV' THEN '10' WHEN 'DEC' THEN '11' WHEN 'JAN' THEN '12' WHEN 'FEB' THEN '13' WHEN...END
let me know if it did solve the issue...
