Multiple values based on LOV in report

Hi,
I have a checkbox on a form where I can select values like e-mail, fax, post.
And then I have report that has a column for confirmation type that is based on same LOV as the checkbox.
The problem is that wen there is one value selected it shows correctly in report that e-mail for example. But when I have multiple values there it shows P:E only not Post, E-mail as it should. So when there are multiple values it shows only LOV return values not display values.
How can I get it to show display values instead of return values when there are multiple values (Post, E-mail instead of P:E)?
Thank you a lot.

anyone?

  • OLAP on 11g and Materialised Views with Multiple Value-Based Hierarchies

    Hello OLAPians
    I am trying to setup Orable BIEE to report on an OLAP cube with pre-aggregated data. As OBIEE is not able to hook into the OLAP directly i have to create an SQL cubeview.
    Currently i am on a 10g OLAP environment and am using the oracle sample SQL cubeview generator to create an SQLview of my cube.
    The cube itself has multiple dimensions and these dimensions have multiple VALUE-based (ragged) hierarchies and dimension members can be shared across hierarchies also.
    Initially i had a problem running the view generator plugin because there is a bug within it that does not finish if there are multiple value-based hierarchies present. I was able to get around this by manually editing the limitmap for the cubeview and manually creating the SQL view.
    The question that i want to ask is how robust is the 11g materialised views with multiple value-based hierarchies and the sharing of dimension members across different hierarchies?
    Has anyone successfully been able to create a cubeview and import it into OBIEE without the hassle of manually editing the limitmap?
    A problem arises with the value-based setup whereby if the client creates a newer depth in the ragged hierarchy, i need to manually create the limitmap and the cube-view over again, and then re-map the BI Administration mappings.

    The simple answer to your question,
    how robust is the 11g materialised views with multiple value-based hierarchies...?is that materialized views are not supported on top of value-based hierarchies in 11g. The reason is that it is not possible to write a reasonable SQL statement that aggregates a fact over a value-based hierarchy. Such a SQL statement is necessary if we want to create a rewritable MV on top of the cube.
    But I suspect this is not what you are really asking. If you are trying to set up OBIEE on top of the cube in 10g using the view generator, then you will probably want to use the "ET VIEWS" that are generated automatically in 11g. These are generated whether or not you enable materialized views on top of your cube. I am not aware of any issues with the generated value-based hierarchy view support in 11g. Members may be shared between value hierarchies and you will not need to generate or modify limit maps.

  • [UIX] How To: Return multiple values from a LOV

    Hi gang
    I've been receiving a number of queries via email on how to return multiple items from a LOV using UIX thanks to earlier posts of mine on OTN. I'm unfortunately aware my previous posts on this are not that clear thanks to the nature of the forums Q&A type approach. So I thought I'd write one clear post, and then direct any queries to it from now on to save me time.
    Following is my solution to this problem. Please note it's just one method of many in skinning a cat. It's my understanding via chatting to Oracle employees that LOVs are to be changed in a future release of JDeveloper to be more like Oracle Forms LOVs, so my skinning skills may be rather bloody & crude very soon (already?).
    I'll base my example on the hr schema supplied with the standard RDBMS install.
    Say we have an UIX input-form screen to modify an employees record. The employees record has a department_id field and a fk to the departments table. Our requirement is to build a LOV for the department_id field such that we can link the employees record to any department_id in the database. In turn we want the department_name shown on the employees input form, so this must be returned via the LOV too.
    To meet this requirement follow these steps:
    1) In your ADF BC model project, create 2 EOs for employees and departments.
    2) Also in your model, create 2 VOs for the same EOs.
    3) Open your employees VO and create a new attribute DepartmentName. Check “selected in query”. In expressions type “(SELECT dept.department_name FROM departments dept WHERE dept.department_id = employees.department_id)”. Check Updateable “always”.
    4) Create a new empty UIX page in your ViewController project called editEmployees.uix.
    5) From the data control palette, drag and drop EmployeesView1 as an input-form. Notice that the new field DepartmentName is also included in the input-form.
    6) As the DepartmentName will be populated either from querying existing employees records, or via the LOV, disable the field as the user should not have the ability to edit it.
    7) Select the DepartmentId field and delete it. In the UI Model window delete the DepartmentId binding.
    8) From the data controls palette, drag and drop the DepartmentId field as a messageLovInput onto your page. Note in your application navigator a new UIX page lovWindow0.uix (or similar) has been created for you.
    9) While the lovWindow0.uix is still in italics (before you save it), rename the file to departmentsLov.uix.
    10) Back in your editEmployees.uix page, your messageLovInput source will look like the following:
    <messageLovInput
        model="${bindings.DepartmentId}"
        id="${bindings.DepartmentId.path}"
        destination="lovWindow0.uix"/>Change it to be:
    <messageLovInput
        model="${bindings.DepartmentId}"
        id="DepartmentId"
        destination="departmentsLov.uix"
        partialRenderMode="multiple"
        partialTargets="_uixState DepartmentName"/>11) Also change your DepartmentName source to look like the following:
    <messageTextInput
        id=”DepartmentName”
        model="${bindings.DepartmentName}"
        columns="10"
        disabled="true"/>12) Open your departmentsLov.uix page.
    13) In the data control palette, drag and drop the DepartmentId field of the DepartmentView1 as a LovTable into the Results area on your page.
    14) Notice in the UI Model window that the 3 binding controls have been created for you, an iterator, a range and a binding for DepartmentId.
    15) Right click on the DepartmentsLovUIModel node in the UI Model window, then create binding, display, and finally attribute. The attribute binding editor will pop up. In the select-an-iterator drop down select the DepartmentsView1Iterator. Now select DepartmentName in the attribute list and then the ok button.
    16) Note in the UI Model you now have a new binding called DCDefaultControl. Select this, and in the property palette change the Id to DepartmentName.
    17) View the LOV page’s source, and change the lovUpdate event as follows:
    <event name="lovSelect">
        <compound>
            <set value="${bindings.DepartmentId.inputValue}" target="${sessionScope}" property="MyAppDepartmentId" />
            <set value="${bindings.DepartmentName.inputValue}" target="${sessionScope}" property="MyAppDepartmentName" />
        </compound>
    </event>18) Return to editEmployees.uix source, and modify the lovUpdate event to look as follows:
    <event name="lovUpdate">
        <compound>
            <set value="${sessionScope.MyAppDepartmentId}" target="${bindings.DepartmentId}" property="inputValue"/>
            <set value="${sessionScope.MyAppDepartmentName}" target="${bindings.DepartmentName}" property="inputValue"/>     
        </compound>
    </event>That’s it. Now when you select a value in your LOV, it will return 2 (multiple!) values.
    A couple things to note:
    1) In the messageLovInput id field we don’t use the “.path” notation. This is mechanism for returning 1 value from the LOV and is useless for us.
    2) Again in the messageLovInput we supply “_uixState” as an entry in the partialTargets.
    3) We are relying on partial-page-refresh functionality to update multiple items on the screen.
    I’m not going to take the time out to explain these 3 points, but it’s worthwhile you learning more about them, especially the last 2, as a separate exercise.
    One other useful thing to do is, in your messageLovInput, include as a last entry in the partialTargets list “MessageBox”. In turn locate the messageBox control on your page (if any), and supply an id=”MessageBox”. This will allow the LOV to place any errors raised in the MessageBox and show them to the user.
    I hope this works for you :)
    Cheers,
    CM.

    Thanks Chris,
    It took me some time to find the information I needed, how to use return multiple values from a LOV popup window, then I found your post and all problems were solved. Its working perfectly, well, almost perfectly.
    Im always fighting with ADF-UIX, it never does the thing that I expect it to do, I guess its because I have a hard time letting go of the total control you have as a developer and let the framework take care of a few things.
    Anyway, I'm using your example to fill 5 fields at once, one of the fields being a messageChoice (a list with countries) with a LOV to a lookup table (id , country).
    I return the countryId from the popup LOV window, that works great, but it doesn't set the correct value in my messageChoice . I think its because its using the CountryId for the listbox index.
    So how can I select the correct value inside my messageChoice? Come to think of it, I dont realy think its LOV related...
    Can someone help me out out here?
    Kind regards

  • Return multiple values from dynamic lov in apex 3.2.1

    Hi
    I need to create a dynamic lov that displays multiple values from a table and RETURNS multiple values into display only fields in a form page to be saved to the database
    For example
    dynamic list of value name SERVER
    select name || ',' || life_cycle d, name r
    from sserver
    order by 1
    This SERVER LOV is attached to the P4_SSERVER_NAME field in the form.
    However this only returns sserver. name into the P4_SSERVER_NAME field in the form. I would need to capture the life_cycle field as well and populate the P4_LIFE_CYCLE field in the form as well. How does one do this?
    I have searched this forum however could not find a thread that fit my situation. i saw that in 4.2 there is dynamic action however unable to upgrade at this moment.
    any suggestions are greatly appreciated.
    thank you

    Hi CRL,
    One method is to set the value of your P4_LIFE_CYCLE item via APEX_UTIL.set_session_state
    To do this you need to create a Page Process
    Type PL/SQL anonymous block
    Process Point On Load - Before Header
    The source for the Process might look like this: DECLARE
       l_life_cycle   VARCHAR2 (50);
    BEGIN
       SELECT life_cycle
         INTO l_life_cycle
         FROM sserver
        WHERE :p4_sserver_name = sserver.name;
       APEX_UTIL.set_session_state ('P4_LIFE_CYCLE', l_life_cycle);
    END;Jeff

  • Passing multiple values to a parameter in report

    Can anyone help me how to pass multiple parameters to a parameter in my report.
    As user is able to select multiple values from list of values , can I pass the selected values to calling function.
    Suppose if User selects Value1,Value2,Value3 from list of values of a parameter P_Org,
    I need to pass all these values to parameter P_Org in my Before Trigger Function in Discoverer reproting tool.
    Thanks in advance

    I have a Before trigger Function to which the parameters will be passed.
    Suppose if User selects multiple values for a parameter then how to pass these multiple Values to that parameter?
    eg:In first Workbook Before Trigger is fired and the paramters for the trigger are
    'par1','par2','par3' etc.
    If User selects multiple values for a parameter 'par1' from the list of values displayed then how to pass all these values to 'par1' in Function?
    After firing the trigger rows are inserted in a temp_table .My second Workbook will
    fetch the rows inserted in this Temp Table.
    I hope u understood what my requirement is...

    I have the header part and main part,
    and also there are page numbering, with the order number field set as order_number it will output single number , but the page order is wrong
    102005000,102005001 will be like header page: 102005000 1/4 102005001 2/4, main page 102005000 3/4, 102005001 3/4

  • How to pass multiple values from master to child report

    Hello,
    How would I pass multiple prompts from the master to child report? So for example, say I want to pass a 'Country' value along with a 'City' value
    Would it be?
    ="<a href=\"../../opendoc/openDocument.jsp?iDocID=ASQlgCemIOlEid1HHUlzyPs&sDocName=DocTest&sIDType=CUID&sType=wid&sWindow=Same&lsSCountry="+[Country]+"&lsSCity="+[City]+"\</a>"
    Thanks,
    Carter

    Carter,
    what is the syntax for this?
    It is exactly how you have posted in your original note.
    "&lsSCountry="+[Country]+"&lsSCity="[City]
    This will work providing the target report has a prompt called "Country" and another prompt called "City".  Note that your prompt and what you pass between the &lsS and the equal (=) must match exactly, otherwise OpenDocument will not communicate the prompt title to InfoView properly and InfoView will stop and execute the prompt to get the info it needs before running the report.  Have you tried what you've posted originally to see if it executes without a problem?
    Thanks,
    John

  • Insert a field twice (that has multiple values) onto same row in report

    I am new to design so hopefully this is an easy question...
    I have three tables in my report that are linked.
    Table 1  "TMDE"
    Mfg
    Model
    Type_Id  (Linked to "FEE(PRICE)"
    Table 2 "FEE"
    Price
    Service_ID (Linked to "SERVICE(ID)"
    Table 3  "SERVICE"
    ID
    Service_Type
    What I am trying to do is create a report that displays two different prices based on two diffent Service "ID"'s on the same row.
    My report keeps creating a second row for the second Service "ID"
    Example:
    MFG      MODEL    TYPE                         PRICE
    Fluke      87         Calibration                  $40.00
    Fluke      87         Calibration w/data     $60.00
    What I woiuld like to see is:
    MFG     MODEL                Calibration $        Calibration w/data $
    Fluke     87                           40.00                     60.00
    Can you help?

    Thanks Noel but I don't think that is the answer.
    Let me try to explain a little further...
    My TMDE table has a field called "Type_ID".  Let's say that record 1 has a "Type_ID" field value of 27.  The "Typer_ID" field is linked to the PRICE table. The linked field in the PRICE table is called "ID" "ID" may have several 27 valuies for the different prices. These prices are based on the PRICE"Service_ID" field.
    Hopefully, this will explain it better...
    TABLE:TMDE 
    MFG:Fluke;   MOIDEL:87;   TYPE_ID:27 (linked to PRICE:ID)
    TABLE:PRICE
    ID:27;        FEE:40;    SERVICE_ID:1 (linked to SERVICE:ID
    ID:27;        FEE:50;    SERVICE_ID:2 (linked to SERVICE:ID
    ID:27;        FEE:60;    SERVICE_ID:3 (linked to SERVICE:ID
    TABLE:SERVICE
    ID:1;  TYPE:Calibration
    ID:2;  TYPE:Calibration w/data
    ID:3;  TYPE:Calibration-Accredtied
    What I would like to see is:
    MFG       MODEL       Calbration price          Calibration w/Data Price
    Fluke      87                       40                                     50

  • How to show multiple values for Unique records in Report

    Here's my question/problem:
    I've joined two tables, one table (TBL1) contains an object id (OBJ_ID) that repeats and the other table (TBL2) contains a date (DT), object type id (OBJ_TYP_ID), and object type description (OBJ_TYP_DES). The tables are joined by an inventory id (INV_ID).
    The OBJ_ID repeats and has a Date value for each record. I want to report an unique OBJ_ID and show each Date for a particular OBJ_ID in multiple Columns.
    An example of the current resultset looks like this:
    OBJ_ID OBJ_TYP_ID OBJ_TYP_DES DATE
    1 1 TYPE1 4/1/2009
    2 1 TYPE1 4/1/2009
    3 1 TYPE1 4/10/2009
    1 2 TYPE2 5/3/2009
    3 1 TYPE1 3/30/2005
    4 1 TYPE1 4/1/2009
    5 1 TYPE1 4/1/2009
    5 2 TYPE2 5/1/2009
    1 1 TYPE1 4/3/2007
    1 1 TYPE1 3/30/2005
    I want to express the resultset like this:
    OBJ_ID OBJ_TYP_ID OBJ_TYPE_DES DATE1 DATE2 DATE3
    1 1 TYPE1 4/1/2009 4/3/2007 3/30/2005
    1 2 TYPE2 5/3/2009
    2 1 TYPE1 4/1/2009

You seem to have an instictive feeling that creating a separate table just for a query is inefficient. You instinct is 100% correct. Maybe in Oracle 7 there was a reason to do that, but today you can query results of other queries as if they were tables, so temporary tables like you describe are very rarely necessary, let alone convenient.
    What you want to do is pivot the date columns. Here's one way
    WITH     original_query     AS
         SELECT  obj_id
         ,     obj_typ_id
         ,     obj_typ_des
         ,     dt          -- date is not a good column name
         FROM     ...          -- the rest of your original query goes here

    ;As you can see, this adds two layers of queries on top of your original query. One of those layers is probably not needed; depending on what you're doing in your original main query, you can probably compute rnum there, and omit the got_rnum sub-query.
    Also, depending on the relationship of obj_id, obj_typ_id and obj_typ_des, some of what I posted above may not be needed but including it won't really hurt.
    If you want to know more about this technique, search for "pivot" or "rows to columns". A <tt>SELECT ... PIVOT ...</tt> keyword was introduced in Oracle 11, but most of what you'll find when you search for "pivot" doesn't assume you have Oracle 11 (nor does the query above require Oracle 11).
    This assumes you know an upper limit (5 in the example above) of dts that can appear in any line of output.

  • Setting column values based on LOV selection

    Hi All,
    I am using JDeveloper 11.1.2.2.0. I have a table eg: Department table, in Dept Id, I have defined LOV for that field. My requirement is, based on the LOV selection, I want to set the other column values. I am using InputTextwithLOV in list type. How to achieve this?
    I tried mentioning that in the List return values. But it is not setting the values.
    Regards,
    Infy

    Hi,
    if you use a model driven LOV then when configuring the LOV you can map additional attributes. When you build a model driven LOV you at least once tell it which LOV attribute should be used to update the DeptId field. You can do the same for additional attributes

  • Get Variant Attribute Should Search for and return multiple values based on RegEx

    I am using Variants as lookup tables (see this article):
    Using Variant Attributes to Build a Dictionary or Look-up Table
    I would like to be able to use some sort of wildcard to return multiple results from the Get Variant Attribute VI (all results are of the same type, and I don't know the exact names of all the results - those two points make this idea distinct from this idea: Set/Get Variant Attribute for Multiple Attributes).
    Ideally the wildcard would be RegEx.  If it were, the means by which you specify what to return is standardized.
    In the above example, there would be some ambiguity in terms of whether or not you would want to return a result or an array of results given an input, and I doubt you could detect and assume RegEx is what the programmer desires to use.  So I think this means a new input would be required to specify whether or not the "name" input of the Get Variant Attribute VI should be interpreted as a RegEx query.
     

    Why RegEx? Why not SQL query? Why not filename wildcard matching?
    I don't see anything that makes RegEx special. For this kind of functionality, the code that you've written seems like exactly the right way to do it rather than bolting a RegEx parser or any other system into the primitives or clouding the palette with a bunch of primitives to support various search functions. I could see a primitive that takes a VI refnum that has a conpane of string in/boolean out that you would pass in to supply the filter functionality that you want for any given application, but even that I'd lean toward just letting that be a library that someone writes on top of the primitives. Yes, there is some memory reduction that can be done if it is internal to the primitives, no question about that. But there are so many variations in how to do that filtration/sorting/etc that I'm not confident that any prim would cover a sufficient use case to be worth it. I could be wrong here ... let's see what other comments come in.

  • Sorting report by column based on LOV problem...

    All,
    I have an issue with a report I have written.
    I have an LOV based on a sql where which returns an ID as a return value and a CODE as a display value.
    Lets say the LOV returns the following results:
    Return, Display
    1, V
    2, A
    3, T
    When I click on the item column heading to sort the report based on that column the records are in the order 1, 2, 3 and not A, T, V.
    So it looks like it is sorting the results based on the return value and not the display value.
    Is this a feature of displaying items based on LOVs in reports and then sorting on them or am I missing something.
    Hopefully, someone can help me out here as it is driving me mad.
    Regards
    ChrisR

    Chris,
    This didn't change in 3.1 and that is definitely not a bug but a feature. The solution I
    propose is a simple workaround for the special cases of LOV display columns or columns
    where you have an image but still want to do sorting.

    Hello Shweta,
       Are you running the report in the Analyzer excel or Web?
    May be you can check the following:
    1. Use the latest FEP. It is working for me.
    2. May be the other values that you selected do not have corresponding keyfigures values. Hence it is showing only the first one.
    Try selecting other values ( except first one selected this time )
