Partial result set in LOV

I am working with BO XI R3 and back end as DB2.
I am facing a partial LOV results set:
From my analysis I have the following:
1)This error occurs with a particular table
2)The number of rows that are being fetched from the database are 44,018,911 rows (nearly 44 million) out of which 178,940 rows are unique ones
3)These rows are not cached/stored daily. Hence each and everytime the report is run it has to fetch from the DB and bring it to the report.
4)On the Universe front, checked with the Universe File-->Parameters tab and "Limit size and time" are unchecked
5)On the report front there is no limiter for the number of rows.
I am not sure but where the tuning has to be done? At the DB front (DB2 is my back end) or on the Universe front (BO XIR3). 1 ) Which would better 2) In case the tuning has to be done on the Universe front how does it need to be done?

Are you getting this one on the Webi report Lovis or Deski Report
If its a webi report you need to change in the Webintelligence Processing server Properties.
The Default vales fro the Maximum List of values size entries is 50000 Lovs

  • Af:inputListOfValues sets value of first item in result set when using enter key or tab and component set to autosubmit=true

    I'm using JDev 11.1.1.6 and when I type a value into an af:inputListOfValues component and hit either the enter key or the tab key it will replace the value I entered with the first item in the LOV result set. If enter a value and just click out of the af:inputListOfValues component it works correctly. If I use the popup and search for a value it works correctly as well. I have a programmatic view object which contains a single transient attribute (this is the view object which is used to create the list of value component from) and then I have another entity based view object which defines one of its attributes as a list of value attribute. I tried using an entity based view object to create the LOV from and everything works as expected so I'm not sure if this is a bug when using programmatic view objects or if I need more code in the VOImpl. Also, it seems that after the first time of the value being replaced by the first value in the result set that it will work correctly as well. Below are some of the important code snippets.
    Also, it looks like it only doesn't work if the text entered in the af:inputListOfValues component would only have a single match returned in the result set. For instance given the result set in the code: Brad, Adam, Aaron, Fred, Charles, Charlie, Jimmy
    If we enter Cha, the component works as expected
    If we enter A, the component works as expected
    If we enter Jimmy, the component does not work as expected and returns the first value of the result set ie. Brad
    If we enter Fred, the component does not work as expected and returns the first value of the result set ie. Brad
    I also verified that I get the same behavior in JDev 11.1.1.7

    I have found a solution to this issue. It seems that when using a programmatic view object which has a transient attribute as its primary key you need to override more methods in the ViewObjectImpl so that it knows how to locate the row related to the primary key when the view object records aren't in the cache. This is why it would work correctly sometimes but not all the time. Below are the additional methods you need to override. The logic you use in retrieveByKey would be on a view object by view object basis and would be different if you had a primary key which consisted of more than one attribute.
    @Override
    protected Row[] retrieveByKey (ViewRowSetImpl viewRowSetImpl, Key key, int i) {
        return retrieveByKey(viewRowSetImpl, null, key, i, false);
    @Override
    protected Row[] retrieveByKey (ViewRowSetImpl viewRowSetImpl, String string, Key key, int i, boolean b) {
        RowSetIterator usersRowSetIterator = this.createRowSet(null);
        Row[] userRows = usersRowSetIterator.getFilteredRows("UserId", key.getAttribute(this.getAttributeIndexOf("UserId")));
        usersRowSetIterator.closeRowSetIterator();
        return userRows;
    @Override
    protected Row[] retrieveByKey (ViewRowSetImpl viewRowSetImpl, Key key, int i, boolean b) {
        return retrieveByKey(viewRowSetImpl, null, key, i, b);

  • Create a CF Query Result Set in Java

    I'd like to programatically build a ColdFusion query resultset inside of a Java class and return it to the calling application.  See the Java psudocode below to see what I'm talking about:
    public class MyClass {
         public coldfusion.sql.QueryTable getQuery() {
              // Create a query table object
              QueryTable myTable = ..?
              // Loop through some set of instance data for my class
              for(int c = 0; c < this.myWigets.length; c++) {
                   int row = c+1;
                   myTable.setField(row, nameCol, this.myWigets[c].name);
                   myTable.setField(row, colorCol, this.myWigets[c].color);
              return myTable;
    I've had stuff like this partially working in the past but had issues with things like query of queries and such probably due to the hacks used to create the QueryTable object.  I'm mainly just checking in to see if there has been any progress made in this area.  To me this seems like such an obvious thing for a Java developer working within CF to want to do.  I'm surprised Adobe doesn't have an officially supported API for doing this sort of thing (or maybe I'm just too dumb to find it.)    A few other notes... I'm not using CFX, and I'm not starting with a java.sql.ResultSet otherwise I would use the QueryTable(java.sql.ResultSet) constructor.  I need to build this thing from scratch programatically.
    Thanks for your time.  I hope this question makes sense to someone out there.
    - Mike

    I appologize.  I wasn't very clear with my original question.
    I'm creating an instance of my Java class from within CF using createObject("java", "com.example.MyClass").  So based on the sample code in my original post on the CF side I'd like to do something like this:
    <cfscript>
         myObj = createObject("java", "com.example.MyClass");
         myObj.doSomeStuff();
         myCFQuery = myObj.getQuery();  // Return a CF query from my java class
    </cfscript>
    ... then do stuff like ...
    <cfquery name="mySortedQuery" dbtype="query">
         select     *
         from       myCFQuery
         order      by color
    </cfquery>
    I appriciate your suggestions so far.  I have other solutions working already but they are not ideal.  I was just hoping someone had a clean and as-hack-free-as-possible way of creating a ColdFusion query result set in Java and passing it back to CF.
    Thanks again,

  • SUP 2.1 LDAP error "Partial results returned."

    Hi everybody,
    I'm configuring a SUP 2.1 server to authenticate users using a MS Active Directory server.
    I'm facing the following issue: whenever I try to login to my test app I get the following error:
    Partial results returned. Operation not completed (Unprocessed Continuation Reference(s)).
    even if I set referral=follow and scope=subtree. The strange thing is that I get the same error with a java-based Ldap broser (JXplorer) but not with a non-java one.
    Anyone faced the same issue before?
    Thank you very much,
    Francesco

    Hi,
    thank you for your answer.
    We tried as you suggested but no luck.
    I suspect that this error is due to some AD configuration on this (DEV) server. We tried connecting the LoginModule to a PROD server (with a lot of users) and everything works fine.
    The AD teams told me that the only difference is that the DEV server is not behind a DNS so I have to use the IP address in the configuration.
    Thank you again,

  • Partial results sign Webi

    Hie Guys,
    My report has a yellow triangle sign at the bottom right of the report for partial results. The database for the Universe was recently migrated to a new engine and server. Could this be the reason for the partial results in the report? Thanks.

    Can you do below check.
    Fire the same query in database and see the number of records count.
    Check the record count in BO.
    As you have said, you have already unchecked the universe limit and report limit options, check for below options also.
    What is set as Limit execution time in your universe connection and universe control tab.
    And also in the query properties of report related to execution.

  • Getting Partial Results

    Hi all,
    I'm executing a big report in webi, and I'm getting the partial results message.
    I changed the Universe parameters to 10,000 rows and time limit to 10min but I'm getting just 3 rows, and I know the report has more rows, because I ran it from SQL developer I'm working with Oracle.
    I can not disable the limits, because the standards of my environment don't allow it.
    Do you know why I'm getting just 3 rows? if the limit is 10,000.
    Thank you,
    Marcela

    Were you receiving more records before you put the limit to 10000 records at the universe level?
    If it was the case, increase the limit to 1000000 records.
    The problem with returning only 3 records when the limit is 10000, the record set being returned might be 10000 but due to filters or joins in the front end the records being displayed might be only 3
    About checking if your account/group has custom restriction on it, that needs to be checked under Tools -> Manage Security -> Manage Access Restrictions
    See if there are any entires in that section.

  • BW Web Report Issue - Result set too large

    Hi,
    When I execute a BEx Query on Web I am getting “Result set too large ; data retrieval restricted by configuration (maximum = 500000 cells)”.
    Following to my search in SDN I understood we can remove this restriction either across the BW system globally or for a specific query at WAD template.
    In my 7x Web template I am trying to increase default max no of rows parameters, As per the below inputs from SAP Note: 1127156.
    But I can’t find parameter “Size Restriction for Result Sets” for any of the web items (Analysis/Web Template properties/Data Provider properties)….in the WAD Web template
    Please advise where/how can I locate the properites
    Instructions provided in SAP Note…
    The following steps describe how to change the "safety belt" for Query Views:
    1. Use the context menu Properties / Data Provider in a BEx Web Application to maintain the "safety belt" for a Query View.
    2. Choose the register "Size Restriction for Result Sets".
    3. Choose an entry from the dropdown box to specify the maximum number of cells for the result set.
                  The following values are available:
    o Maximum Number
    o Default Number
    o Custom-Defined Number
                  Behind "Maximum Number" and "Default Number" you can find the current numbers defined in the customizing table RSADMIN (see below).
    4. Save the Query View and use it in another Web Template.
    Thanks in advance

    Hi Yasemin,
    Thanks for all help...i was off couple of days.
    To activate it I can suggest to create a dummy template, add your query in it, add a menu bar component add an action to save the query view. Then you run the template and change the size restriction for result set then you can save it by the menu.
    Can you please elaborate on the solution provided,I created dummy template with analysis and Menu bar item...i couldn't able to configure menu bar item...
    Thanks in advance

  • How can I use ONE Text search iView to event/affect mutliple Result Sets?

    hello everyone,
    i have a special situation in which i have 6 flat tables in my repository which all have a common field called Location ID (which is a lookup flat to the Locations table).
    i am trying to build a page with a free-form text search iView on Table #1 (search field = Location ID).  when I execute the search, the result set for Table #1 is properly updated, but how do I also get Result Set iViews for Tables #2-6 to also react to the event from Text Search for Table #1 so that they are updated?
    i don't want to have to build 6 different text search iViews (one for each table).  i just want to use ONE text search iView for all the different result set tables.  but, in the documentation and iView properties, the text search iView doesn't have any eventing.
    if you have any suggestions, please help.
    many thanks in advance,
    mm

    hello Donna,
    that should not be a problem, since you are detailw with result sets and detail iviews because custom eventing can be defined for those iviews.
    Yes, it says "no records" found because an active search and record selection havent' been performed for it (only your main table does).
    So, yes, define a custom event, and pass the appropriate parameters and you should be fine.
    Creating a custom event between a Result Set iView and an Item Details iView is easy and works. I have done it.
    See page 35 of the Portal Content Development Guide for a step-by-step example, which is what I used.
    For my particular situation, the problem I'm having is that I want the Search Text iView's event (i.e., when the Submit button is pressed) to be published to multiple iViews, all with different tables.  Those tables all share some common fields, which is what the Search iView has, so I'd like to pass the search critera to all of the iViews.

  • Access Subform - Can the Subforms Source Object be defined by an SQL SP result set?

    Hi Guys,
    I can't clearly answer this question with a yes or no.
    I have an Access Sub Form that I am populating with a record set from a Store Procedure. Fairly early on I discovered that for this to work correctly the Source Object for the Sub Form Control must be set first, and most examples (including a working version
    of my own) achieve this by defining an Access Query and setting the Source Object to this.
    What I would really like to do is define the Source Object using the results of a SQL Store Procedure using ONLY code within VBA.
    Now before anyone starts providing alternatives "why don't you just..."  I'm noting now that I have a semi complex solution that makes most non-VBA based approaches ineffective. While it does work at present with an Access Query I'm needing
    to make the result set more dynamic meaning in future I will not know how many columns will be returned or the name of them, only the SP will have this information.
    Thanks in advance!

    Well after much trial and error I've got something which does what I want, although I'm not thrilled that I couldn't do this via my existing ADODB connections, in any case example provided below;
        Dim db As DAO.Database
        Dim qdf As New DAO.QueryDef
        Set db = CurrentDb()
       'qryMyTest refers to a dummy Access query (non pass through). 
        With db.QueryDefs("qryMyTest")
            .Connect = CurrentDb.TableDefs("tblSomeTestSQLTable").Connect
            .SQL = "exec sp_MyTestSP"
            Me.subfrmTest1.SourceObject = "Query.qryMyTest"
        End With   
        Set qdf = Nothing
    I've also marked your response Alphonse as an answer as it lead me onto the right path.

  • How do I create an Event Handler for an Execute SQL Task in SSIS if its result set is empty

    So the precedence on my entire package executing is based on my first SELECT of my Table and an updatable column. If that SELECT results in an empty result set, how do I create an Event Handler to handle an empty result set?
    A Newbie to SSIS.
    I appreciate your review and am hopeful for a reply.
    PSULionRP

    Depends upon what you want to do in the eventhandler. this is what you can do
    Store the result set from the Select to a user variable.
    Pass this user variable to a Script task.
    In the Script task do whatever you want to do including failing the package this can be done by failing the script task, which in turns fails the package. something like
    Dts.TaskResult = Dts.Results.Failure

    You probably are using the same Statement object for both queries? Try creating separate Statement objects for each query. (My guess is this a problem with the way you're using JDBC, not a Servlet issue.)

  • Report Control and Multiple Datasets/Result Sets

    I have four results sets, Plan, Forecast, Actual and SPLY per eight different product lines.  I want to add conditional formatting of background color if actual is above or below Plan and/or Forecast.  The report needs to export properly to Excel.
     Is there a way I can use one control rather than multiple text boxes to display the data, allow for conditional formatting and export to Excel.?  Thanks!
    Environment:
    SSRS 2010
    SQL Server 2012

    Hi blairv,
    If I understand correctly, you have a dataset in the report which include four fields: Plan, Forecast, Actual and SPLY. Each filed contains eight values.
    In SQL Server Reporting Services (SSRS), we can use table, matrix or list display report data in cells. The cells typically contain text data such as text, dates, and numbers but they can also contain gauges, charts, or report items such as images.
    Reference: http://technet.microsoft.com/en-us/library/dd220592.aspx
    In your case, we can use expression to configure these items background color. Please refer to the following steps:
    Click a specific text box in the report. Click BackgroundColor prompt in the Properties dialog box.
    Click Expression prompt. And fill with expression below:
    =IIF(Fields! Actual.Value>Fields! Plan.Valeu Or Fields! Actual.Value>Fields! Forecast.Valeu,”Red”,”Blue”)

    If there are any miunderstanding, please feel free to let me know.

  • Query Error Information: Result set is too large; data retrieval ......

    Hi Experts,
    I got one problem with my query information. when Im executing my report and drill my info in my navigation panel, Instead of a table with values the message "Result set is too large; data retrieval restricted by configuration" appears. I already applied "Note 1127156 - Safety belt: Result set is too large". I imported Support Package 13 for SAP NetWeaver 7. 0 BI Java (BIIBC13_0.SCA / BIBASES13_0.SCA / BIWEBAPP13_0.SCA) and executed the program SAP_RSADMIN_MAINTAIN (in transaction SE38), with the object and the value like Note 1127156 says... but the problem still appears....
    what Should I be missing ??????  How can I fix this issue ????
    Thank you very much for helping me out..... (Any help would be rewarded)

    You may ask your basis guy to increase ESM buffer (rsdb/esm/buffersize_kb). Did you check the systems memory?
    Did you try to check the error dump using ST22 - Runtime error analysis?
