Presentation variable in column formula issue

Hi,
I'm having an issue about putting a presentation variable in a column formula. I'm using obiee 11.1.1.7.141014
I'm adding a text in a formula column where I use two presentation variables: pPeriodo and pAno
pPeriodo invoques the month selected in a prompt and pAno the year. I have to compare different years, so in one member I use @{pAno} when is the selected year and @{pAno-1} when is the prior year.
The result of this (please see the header of the 2nd column):
The problem is when Icompare to next years. So my issue happens when I do an addition to the presentation variable: @{pAno+1}
It doesn't do the sum; it concatenates the value as you can see in the following images
If anyone have a workaround about this, please share.
Regards,
Miguel

Hi Joven
Try @{pAno}+1 instead of @{pAno+1}

    Hi
    I have a date column which should have 2 presentation variables. From date and To date. I created a dashboard prompt on the date column twice with case statements like CASE WHEN 1=0 THEN CALENDAR.D_DATE ELSE TIMESTAMP '1900-01-01 00:00:00' END . Now i have 2 presentation variables FromDate and Todate for the user to select. I have referenced this in the report using a filter with the condition " date between @{FromDate}{1900-01-01 00:00:00 AM} and @{ToDate}{1900-01-01 00:00:00 AM}
    Now i have a column in the report which has a case statement with the following conditions
    CASE WHEN "Dim - Pay Info"."Status Cd" = 'ROC' AND TIMESTAMPADD(SQL_TSI_DAY, -1, @{FromDate}{1900-01-01 00:00:00 AM}) THEN 'Outstanding' --- the condition here is take off a date from the FromDate selected

    What is the syntax error? If you make people have to guess or to examine intensely what you wrote, many will pass on your question, which I don't doubt people did.
    Rather than dive into your syntax, read this blog entry by Venkat which perfectly describes how to build and use date prompts with BETWEEN, including the syntax of wrapping your date prompts with single quotes.

  • Define presentation variable in column header

    I want to display presentation variable in column header.
    I tried both:
    @{p_mycategory}{'My category'} Sales
    @{p_mycategory}{My category} Sales
    but failed to display neither p_mycategory value nor the default 'My category'.
    Any ideas?

    I know to add presentation variable in title or narrative text.
    The issue is in chart series name.
    Assuming I want user to select category, which entered to p_categ.
    The lines graph chart should display one line for the selected category and the second line should display the other\total categories.
    In the legend I want to mention the name of the selected cetegory and not saying 'the selected category' or something like that.

  • 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!

  • How to create Presentation variable for columns and to use it in Narrative?

    Hi All,
    Anybody know how to create presentation variable for a column (i.e., i need to create it in edit formula section itself). And then, I should use it in Narrative section to display that column value. Is it possible? Or do i need to use any other variable for this requirement? If so please let me know, how to create it? This is very urgent requirement.
    Thanks in Advance

    Hi Satya,
    I just want to create a table that should horizontally display the values like below:
         SUID Tag # :123456               Year Mfg: 2007                                                                                     
         Description: computer corporation FA ID#: 4576

         Serial Number: 78945 Flags: c
    Department: Hematology
    User: thenmozhi
    Database: OLAP
    I think we can create this type of report using either Narrative or Static Text. But I am not sure whether it is possible or not? And also another thing is that sectioning is applied for SUID Tag # column. So, depending on the dashboard prompt if the SUID Tag # retrieves two or more values.
    Then the first value for example 123456     and the values for the other columns related to this SUID Tag # value should display in the first page (i.e., page 1). And if the next value of the SUID Tag # for example say 678901 then the values should move to second page that is like this:
         SUID Tag # :678901               Year Mfg: 2008

  • Using multiple value presentation variable in a formula

    I am using 11.1.1.5 version of OBIEE. I have a dashboard prompt that contains a value for a list of departments. I want the user to select multiple values. I am pushing these values into a presentation variable called deptname. I know would the multiple values in a formula. I want to do a filter using a statement like this. I don't get an error. It works for one value but not for many. I have tried to use it with an in clause but can't seem to get that to work either. Formula is below. I have also been playing around with quotes since these are strings. Any help is appreciated. I only want the value in the formula filtered not the whole report which is why I am doing it this way. The below works for one value. Returns blank for more than one value.
    FILTER( "Fact Class Enrollment"."Units Taken") USING "Academic Organization"."Academic Organization Level 5 Desc" = '@{deptname}{Sociology}' )

  • OBIEE 11G Presentation Variable

    Working with two column prompts, and I need one to feed off of the other.  I was thinking I need to set one column as a presentation variable, and create sql for the other, so that it responds to the first.  The columns are Organiztion and Department.  The departments will change based on which organization you select.  How do I start this off?
    Please advise

    SV.......
    Ok....so simply clicking the box didn't quite work fully.  Before I posted this, this morning, I attempted what you suggested.   Column 1 = Org  Column 2 = Dept.   I tried this:    select column 2 from table where column 2 = pvcolumn1.  And of course I set the presentation variable on column 1.  

  • Presentation Variable Value not passing when used in Column Formula.

    Hello Gurus:
    Please help me with my requirement.
    We are trying to show a data backout in report, for example.
    For a Product Group Code of 2435 which belongs to Report Line C059 has a Sales Amount of $4,266.90 and in report we want the same Sales Amount of $4,266.90 to be shown as -$4,266.90 (Negative) under a Report Line C080.
    So in a report there should be same Sales Dollars as Positive for C059 (from Source) and Negative Sales Amount for C080 (Condition to be applied in Report).
    Solution I Tried
    I tried to create a Presentation Variable (SQL- Which would fetch me Sales Dollars for Product Group Code 2453) which returns with $4266.90 and then applied it in Answers in Logic (Case when Report Line = C080 then @{Presentation Variable}*-1 Else Sales Dollars END).
    Issue I am facing:
    Presentation Variable is coming as 0 and if i give any Format (Default Value) it shows the same default value in report. I checked the SQL i used and even when I Preview the Variable its showing me $4,266.90, but not in report.
    Please let me know a way to get this Presentation Variable value into my reports.
    Also please let me know if i can achieve this requirement in any other way.

    Thanks for your reply Paul. But there is no Invoiced Amount for Report Line - 'C080' from source. Invoiced amount of C059 should show as -ve Invoiced amount for CO80.
    In a report C059 should show +ve Sales Dollars and C080 should show same amount as -Ve Sales Dollars.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           

  • 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.

  • Date variable in a column formula

    Hi
    I am having trouble using date-values from a Dashboard Prompt in a column formula in Answers.
    The situation:
    I use a dashboard prompt to select a date, the selected date stored in a presentation variable ('production_end'). In an answers request, I would like to use the 'selected_date' value to filter values for one column:
    FILTER("Measures new".Produced USING(Calender."Full Date" = @{production_end}{timestamp'2009-07-31 00:00:00'))
    Error after prompt execution:
    Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P:OI2DL65P
    State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 27002] Near <00>: Syntax error [nQSError: 26012] . (HY000)
    SQL Issued: {call NQSGetQueryColumnInfo('SELECT FILTER("Measures new".Produced USING(Calender."Full Date" = 2010-07-14 00:00:00 FROM source_db')}
    SQL Issued: SELECT FILTER("Measures new".Produced USING(Calender."Full Date" = 2010-07-14 00:00:00 FROM source_db
    There is no problem using the production_end in a column filter to filter the whole request, the error only shows up whenever I try to use it in a column formula.
    Hope you can help.
    Thanks

    Hi Kart,
    I think I found the problem and the solution.
    I use a dashboard prompt with a default value based on a repository variable ('today'). The prompt feeds a presentation variable ('prod_end').
    In the answers request I use prod_end in the following column formula (I changed the request slightly compared to the ones we were discussing - the basic functionality of using the presentation variable is the same):
    MONTH(timestamp'@{prod_end}')
    That combination leads to the follow error when opening the dashboard for the first time:
    State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000]
    [nQSError: 10058] A general error has occurred.
    [nQSError: 46047] Datetime value TIMESTAMP '2010-07-15 00:00:00' from TIMESTAMP '2010-07-15 00:00:00' does not match the specified format. (HY000)
    The first timestamp probably being the timestamp defined in my column formula, the second one (the one selecting from) probably being the repository variable definition.
    Solution:
    If I default the dashboard prompt using an sql statement to refer to the repository variable 'today' it works
    Default prompt to:
    SELECT Calender."Full Date" FROM OLS where Calender."Full Date" = VALUEOF("today")
    Thanks for your help

    Thanks Goran!!
    I've created prompts by selecting columns from the logical tables (i.e. I've selected 2 different cols of datatype DATE...inorder to assign 2 presentation variables).
    Yes I m using calendar widget for prompts.
    I haven't included any filter in my report. I m trying to display a metric when it satisfies the case statement.
    I will defintley go through the blogs you mentioned for better understanding.

    State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 46046] Datetime value 1/1/2005 does not match the specified format. (HY000)
    SQL Issued: {call NQSGetQueryColumnInfo('SELECT "Transaction Dates"."Transaction Date", TIMESTAMPDIFF(SQL_TSI_DAY, DATE ''1/1/2005'', DATE ''1/2/2006'' FROM "Dates"')}
    SQL Issued: SELECT "Transaction Dates"."Transaction Date", TIMESTAMPDIFF(SQL_TSI_DAY, DATE '1/1/2005', DATE '1/2/2006') FROM "Dates"
    Can anyone help me to reolve this date format issue?
    Thanks,
