How to pass the page item data from tabA to TabB of a discoverer report

I have a discoverer repoort, it is master_detail (Dept-Emp) report
TabA is a master worksheet, which has a page item Deptno
(the data is from a customized query)
TabB is detail report which has a Deptno as the page item
which show the emp detail info on this deptno
(the date is from another customized query).
What I want to do is;
When I change the Deptno in TabA, TabB should automatically change to the deptno of Tab A when I click TabB.
How can I pass the page item deptno from TabA to page item of TabB?
Thanks for your help

Hi.
You are absolutely right, you cannot create a link from Page Item.
My Idea was (and I'm sorry taht I didn't mention it at the beginning) to create one link for each and every column in the report in the TabA.
All these links would be exactly same and pass the Deptno to the TabB.
So the end user can click wherever he wants (all cells on the worksheets have the link to the TabB) and he is always redirected to the TabB with the Department parameter seted to Deptno Page Item from TabA.
As I already said before, it is not exactly what you expected, but it's probably the best you can get out of Plus.

  • How to remove the Page Item in thin Bean JSP

    Hi, I'm wondering how to remove the Page Item in JSP developed by BIBeans, since I have tried to remove the Presentation's Page Item in BiBeans Catalog, but with no result in JSP. Thank you!
    Jeff

    There are two ways to do this:
    1) If you want to remove and individual dimension from a presentation, you can hide the dimension. This can be performed directly from within QueryBuilder. Within the first section of Query Builder that shows the selected measures selected and associated dimensions, simply remove the required dimensions from the right dialog panel.
    2) To hide all page items within a presentation, simply add the following the property, pagingControlVisible="False", to the presentation tag in your JSP. For example:
    <orabi:Presentation location="Local Computer Sales/Products/KPI Sales Prior Period and Prior Year" id="BIProductKPIs_pres2" pagingControlVisible="False"/>

  • How to track the flow of data from R/2 to BI ?

    Hi Experts,
    Question: How to track the flow of data from R/3 to BI ?
    I want to load master data from R/3 to BI. In BI, i create an infopackage to load data from R/3. Under processing tab i set it as "PSA and then in the InfoObject (package by package)". Its a Full update.
    Now, i start the update to InfoObject. The load goes on well.
    Now, i want to track the flow of data from the master data table in R/3 to Datasource in R/3 then Extractors and then in the PSA in BI and then till the InfoObject. That is the complete flow of data from source table (in R/3) to Target table (in BI).
    Please help me know how this can be done. (For example lets take cost element master data)

    Hi,
    Data flow :

    When u right click on the Master Data Info object -> Select Data flow.Then  it will  show u the details like DS name,IS (If 3.x)
    Once u know the DS then you need to find out the source tables for the R/3 DS.This information will get using ROOSOURCE or ROOSFIELD tables  or help.sap.com.

  • How to Pass the internal table data?

    DearAll,
    How to pass the Data of one internal table on a 1.html page to another html page for output, in BSP Application.
    regards.

    Hi ,
    In the onInputProcessing event of the first page , write the following code...
    call method NAVIGATION->SET_PARAMETER exporting
        name = 'it_filt_cur'
        value = it_filt_cur.
    Here it_filt_cur is internal table.
              NAVIGATION->GOTO_PAGE('next.htm').
    In the next page , you can make the internal table as auto in the attributes.
    Since you have made the itab as auto transfer , you can directly access the itab in the initialization event of the next page if it is stateless.

    Thanks for quick response.
    In the smartform under the Form Interface->Tables tab

    LT_PRDLBL LIKE ZPRDLBL. If I define TYPE instead of LIKE I get the error message saying "FLAT TYPES may only be referenced using LIKE for table parameters".
    In the main window I have created LOOP, in which I have ticked the internal table and

  • How to place the page items horizontal in pivot table in OBIEE

    Hi experts
    In pivot table i have two pages items. And i want to place them horizaontaly. So how can i achieve this.
    for Ex: I have placed my two columns in page section of pivot table: Year,city.
    then i need as ;
    Year City
    where year is one dropdown list and city is another drop down list.
    Thanks in advance
    Regards
    Sunil

    Hi,
    We can seperate the page items using 'Start New Page Drop Down', but the item will be displayed in the next line.
    I think you would like to show them side by side i.e, horizontally..
    If it is, i think it is not possible as of OBIEE 10.1.3.3.. not sure about 10.1.3.4..
    Please let me know if my assumption is wrong.. I will be very happy if anyone corrects me..:)

  • How to consume the Calendar Exception details from Project Server 2013 to an SSRS report using PSI ?

    Hello,
    Can anyone guide me how to access the calendar exception details from Project Server using PSI?
    I need to extract calendar details of enterprise resources , like exception name, exception type, exception start date and exception end date into my SSRS report hosted in SharePoint 2013 and 2010.
    I would be helpful if I can get a sample of this. I have read through many PSI documents in fact still going through ,what  PSI does and doesn't ,  PSI methods etc. from Project Server SDK and MSDN . Moreover, I
    am a beginner in .NET programming. I am confused and have lots of questions in my mind, like which PSI service should be used in my report(is it  just Calendar.svc), can we pull the details as XML type data source my SSRS report ,are
    there any other configuration settings apart from " setting up an event handler by installing an event handler assembly on each Project Server computer in the SharePoint farm, and then configuring the event handler
    for the Project Web App instance by using the Project Server Settings page in the General Application Settings of SharePoint Central Administration" (as per prerequisites for PSI in SDK) , how can I implement authentication settings

    Hi Rani,
    I see one issue in the Q2 with the where statement:
    and pv.segment1=(pv.segment1=:VENDOR_NUM or pv.vendor_name=:VENDOR_NAME)
    the right one should be
    and pv.vendor_id = :VEN_VENDOR_ID
    the variable VEN_VENDOR_ID you have to select from the first query Q1. Add here after select
    pv.vendor_id VEN_VENDOR_ID,
    Regarding the other question about the data types, well, number and varchar2 is fine, perhaps char also, but go with varchar2 instead.
    One last note: you should not mix uppercase and lowercase, keep it clear and structured, check your element names and values.
    Best Regards

  • How to pass a cluster of data from one VI to another

    Hi all,
    I've got a cluster of controls on my main application VI that I am using to accept data of various types from the user.Next I want to pass this cluster to the input cluster control of another VI perfectly on the generation of a user event. That is, if I have 3 numbers, 2 strings and 2 time stamps in the cluster on the main VI, I want to pass on that exact same data to the control input cluster of the second VI in the same sequence, having the same values.
    How do I do this?
    Here is a snapshot showing the cluster controls on my main VI and the code for my second VI.
    I want to pass the data into the input cluster 'data'. I tried calling the second VI into my main VI and directly hardwiring the cluster and then using an 'Unbundle by Name function' to separate the data, as shown. But this doesn't seem to work properly.
    Regards. 
    Solved!
    Go to Solution.

    The 2 clusters much be identical, then it should work smoothly. To ensure that they are, make a type-def of the cluster and use for both. From what i can see of your code it's clean and correct and it really shouldn't cause a hassle. What's (not) happening?

  • How to obtain the pricing condition data from sales data?

    Hi all!  I have googled many times and read through many sites to understand how I can obtain the pricing condition data that's specific to a specific sales line.  However, the answer I got usually are as follow:
    Tables to be used:
    KONV
    KONH
    KONP
    VBRK
    VBRP
    And the thing is to obtain KNUMH data from VBRP and link it to KONP which will get the exact pricing condition data that's relating to the specific transaction.
    However, my challenge is that the field KNUMH in either VBRP or VBAP, it is empty.  Therefore, how can I have a report with my sales data as the primary file, and appending the pricing condition data so that I can analyze the different kinds of pricing condition types that the company is using.  The only field that I can use is KNUMV which does not give me the pricing condition that was used in this particular invoice line.
    I also know that there is the A*** tables, which contains the KNUMH file.  However, this file is split into many different tables.  Thus, is there a more efficient method to download all the data?  In any case, I still do not know how to link to my sales data.
    FYI, I only have SE16N and VK13's access.
    I hope that someone can help me, please!
    Thank you!

  • How to get the week start date from ISO week number

    Hi,
    I have a table with the following stucture
    Year    error    Week1     week2   week3 ......week53
    2012       error1     2           4         2             1
    2012       error2    3          0        1                 1I was hoping to get something like select year, error, week1||'Week start date which is a monday of that week' , week2||'Week start date,again monday',....week53 from table
    Any suggestions please?
    Thanks,
    Sun

    Hi, Sun,
    To see when week N started, add 7 * (N - 1) days to the beginning of the year. (By definition, the beginning of the ISO year is the start of week 1 of the ISO year.)
    To see when week 22 of the current year started:
    SELECT  TRUNC (SYSDATE, 'IYYY') + (7 * (22 - 1))
    FROM    dual
    I hope this answers your question.
    If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
    Explain, using specific examples, how you get those results from that data.
    Always say what version of Oracle you're using.
    See the forum FAQ {message:id=9360002}

  • How to extract the size and date from a given file

    Hi,
    I want to extract the size and date of a file (it can be either a video, audio or text file) that the user points to the location of. But I am not sure how. Does Java have an api that can do this? If not is there some other way of doing this? Can anyone help? Thanks in advance.

    Have a look at java.io.File, specifically
    public long lastModified()
    This format returned (I find) is nasty, so then use java.util.Date (or java.sql.Date, look the same on the surface to me) to format it.
