Graphing Counts & Using Counts as Variables

Hey all
My team was just set-up in OBIEE and our data model completed was built for us, now it's on us to create all the dashboards that we have currently in Crystal Reports. We only have minimal training documentation which I think is intended for non-IT people because it doesn't get much past sorting columns.
What I'm trying to accomplish is to use the count() function as a variable, for instance (we're a helpdesk team) if I wanted to divide the total number of tickets submitted by the amount of days in the period then graph on that to show trends etc. This is useful in a lot of our data.
The exact report I'm making now I want to show the count of tickets by category year to date and then next to it on the same graph that same data for the week from the prompt (I'll read up on passing a variable from the prompt to the report). I've tried creating a column and then using MAX RCount and other methods that I could think of but I can't get the count to reset after each category. If it were possible to graph counts then this would be easy (well except the filtered week data) but from everything I've read I have to create a column and as I said I can't get the equation right.
Any help would be appreciated

  • How to get file count in variable?

    dear all,
    how to get file count in variable?

    Naseer

    Hi Nazeer ,
    It wont take much time .. so simple :- )
    Create one os comand step
    ( for unix) Use
    wc -l filename.txt > someoutputfile.txt
    Now the number of lines in your file will be there in the output file ( someoutputfile.txt )
    Step2 :-
    Now use Cezar's logic to fetch the variable value ( file count ) from the output file .. ( select value for a variable from a file )
    This will not take eeven a second to finish the job.

  • Using the system variable cpInfoQuizAttempts

    My content is run through an LMS. I am trying to used advanced code using the system variable cpInfoQuizAttempts so that a caption appears when the variable value = 3. Apparently, I can't utilize the value of this variable; in fact, I can't even display it's value in a caption. I am trying to create advanced code on a course page that displays a caption like "You canot take this quiz again because you have already taken it the maximum number of time possible." once someone has taken the course the maximum number of times.  I assume this is the variable Captivate is using to show # attempts on the results page. I tried this with just a user variable but the value of the user variable is not stored or saved on the LMS. Therefore, if you have a maximum number of 3 attempts and someone takes the quiz twice, if he logs off and logs back on, the previous value (2) is not saved and the value reverts to the default (0).
    Any ideas how this could be done?
    KO

    I'm pretty sure that all user defined variables are saved in suspend_data in the LMS. Therefore your user defined variable should be there, but I don't see any way how Captivate would be able to retrieve it again out of the box.
    I think that the cpInfoQuizAttempts variable refers to attempts done in the same "session". So if fail the test and then retry and fail it would have a count of 2. However, once the user exists the course the variable is no longer available to Captivate.
    As Rick said most LMS' have a function to define max / min attempts of a quiz. However, this most likely requires that you publish the quiz as an independant SCO since the "lockout" would apply for that SCO. Basically if you only have one SCO then your users wouldn't be able to access the content or the quiz if they exceded the max attempts. Your content should therefore be one (or more) SCO(s) and your quiz one separate SCO.
    If I'm not mistaken it's also possible to define the max / min attempts in the SCORM manifest, but this is very geeky.
    If you own and can use Flash you could solve your problem two ways:
    1. Create a Flash file that retrieves the user defined variable from the LMS suspend_data and then sends that back into Captivate. Import the Flash file into your Captivate project.
    2. Create a Flash file that stores and retrieves the attempts in a Shared Object on the users PC and then brings the stored value back into Captivate. Import the Flash file into your Captivate project.

  • Using collections / Bind variables with a PL/SQL functio returning a query

    I have this code, which is supposed to assign collection variables as column names
    FOR i in 1 .. Collection_count -1
    LOOP
    SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=i;

    vQuery:=vQuery || varholder || ', ' ;
    END LOOP;
    I've tried &P341_M1. , :P341_M1, ':P341_M1', varholder
    When I try '&P341_M1' it returns the whole SUM(decode... line as the label
    Basically Im having a hard time using bind variables with the PL/SQL returning a query...anybody?

    Ok so working through this problem more I have realized that the problem is using the for loop i as an index value
    This will get a value:
    SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=2;
    But this won't
    SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=i;
    I'm in the for loop, and use the i variable in other places within this loop...Is there a reason why I can't compare seq_id to i?
    My new code as follows:
    FOR i in 1 .. Collection_count -1 --apex_application.g_f01.COUNT - 1
    LOOP
    varholder:=i;
    SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=2;
    SELECT c002 into varholder FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=4;

    vQuery:=vQuery || :P341_M1 ||i||', ' ;

  • How do you plot multiple curves on the same graph when using a while loop?

    I am writing a program that will plot the IV Output chracterisitcs curves for a MOSFET transistor. I have two sweep variables Vg and Vd. For each Vg valve selected, Vd is swept from its start to stop voltage creating a graph for that Vg valve. Both of the sweeps are done using while loops. Ideally I would like to display all of the Vg plots on the same graph while having the ability to do real-time graphing. Can anyone help me figure this problem out? I have attached my program. Thanks!!

    Hi Tammy & Tica T,
    As far as I see it - this thread is a very bad version of already existing bad version......
    http://forums.ni.com/ni/board/message?board.id=170&message.id=127857
    I expected, that an Applications Engineer from NI knows something about  a Transistor and how an Output characteristic looks like !!  Take a look to a typical Transistor Datasheet ( e.g. n-channel MOSFET) - you will see, that there is no relation of ID vs Time like in your example ( values vs time )  but  IDrain vs VDrain at different VGate's ( no relation to Mr. Bill Gates ).
    Find attached a vi, that in general does what you need - drawing of  curves vs x-axis (XY-graph in use)  - in test_sweep.zip.  And that you geet an impression, how it might be done ...... dynamic Output characteristic of a Transistor with Standard Equipment of a Lab ( Scope + Generator + Power Supply ) find in addition a Frontpanel - picture. One of the interesting points here is - the self-heating effect; visible on ch3 of scope - 5µs Pulse is already a very long time...... This measurement was done in order to compare with our own Transistors......... 
    Hope this helps a little bit to understand, what we are talking about.

  • No difference between using a local variable and a notifier in timed parallel loops?

    The example code "Pass Data With Notifiers.vi" that came with LV 7.1 illustrates using notifiers with parallel loops.  Just looking at two of the loops, the one that generates the sine wave and the one for "User 1", you can change the timing of the two loops and you can change the condition of the "Ignore Previous" status on the "Wait on Notification".  I have a special case of this to consider, where I'm wondering if there's any reason not to use a local variable instead of the notifier:
    Set the delay on the generator portion (which contains the Send Notification) to something very short, say 5 ms.  Set the delay on the User 1 (which contains the Wait on Notification) to something relatively longer, say 200 ms.  Set the Wait on Notification to False.  Now you have a situation where the User 1 loop action is contingent only upon the loop delay time, since each time the loop timer runs the loop there will always be a value in the notifier.  In this case it seems to behave just like the case where you update a local variable in the fast loop and read it in the slow one.
    Is my understanding correct?  Would there be a performance difference between the two methods?  What do you prefer in this situation and why?
    Thanks,
    Hosehead

    Hi H.,
    I think your idea is to write to a Global Variable in the data-producer VI, and read it in the data-consumer VI(?)
    One reason this might be less efficient than using Notifiers is if you want to graph every new value in the "consumer" - or make sure the value read in the consumer has changed at least once since the last loop.
    > since each time the [consumer] loop timer runs the loop there will always be a value in the notifier...
    > Would there be a performance difference between the two methods? 
    If you don't use the Notification "event" to synchronize the producer and consumer, then to be sure the consumer gets a new vaue, you've made the producer loop faster - every 5 ms - a waste of cpu-cycles.  More often the situation is reversed, that is, there's a consumer that needs to see every single new value, and (without events) the consumer must loop faster than the producer (to catch every new value) - this is called polling and it wastes cpu-cycles.
    Just about anytime one's tempted to make a loop execute "fast" to check on some value (or to make sure there's a fresh value,) there's an opportunity to improve performance through synchronization with events (including notifiers, queues, occurrances, semaphores, and rendezvous')

  • Issue with use of shared variables in Crystal Reports 2008 Offline Viewer

    Hi,
    I have a report that contains a number of sub-reports which include drill-down functionality. The report returns data relating to an individual team with the user being able to view top level summary information in each area from the parent report and then drill into the sub-reports to view see more detail. The data returned by the sub-reports is filtered, using sub-report links, based on the team code parameter value given by the user. This parameter field resides in the main report.
    One of the values returned by the main report is the team name. This is passed to each sub-report using a shared variable and each sub-report displays this team name as part of a heading.
    This all works fine in Crystal Reports 2008, but when a report, containing data, is opened using Crystal 2008 Offline Viewer there is a problem with the shared variable. The value is displayed correctly when the user initially drills into the sub-report. However, when the user begins to drill into grouped data within the sub-report the value passed to the sub-report using the shared variable disappears. 
    How can I ensure that, when a report is viewed using Crystal Offline Viewer 2008, the value within the shared variable is not lost when users drill into grouped data within sub-reports
    Thanks

  • Use of global variables like g_cnt_transactions_transferred in the LSMW

    Hi SapAll.
    when i had a look at the some of the LSMW's whic use IDOC as the object of uploading data into SAP from external Files i have found in the coding under the step "Maintain Field Mapping and Conversion Rules" that they use some of the global variables like below
    .if p_trfcpt = yes or sy-saprl >= '46A'.
      EDI_DC40-DOCNUM = g_cnt_transactions_transferred + 1.
    endif.
    .EDI_DC40-CIMTYP = g_cimtyp.
    .EDI_DC40-MESTYP = g_mestyp.
    .EDI_DC40-MESCOD = g_mescod.
    .if p_filept = yes.
      EDI_DC40-SNDPOR = g_fileport.
    elseif p_trfcpt = yes.
      EDI_DC40-SNDPOR = g_trfcport.
    endif.
    my doubt is where i can find these variables 'g_cnt_transactions_transferred ','g_cimtyp','g_mescod','g_fileport','g_trfcport' in the LSMW and what is the use of the variable  'g_cnt_transactions_transferred ' in the LSMW.
    I have treid to find out the above listed variables looking in step 'Maintain Field Mapping and Conversion Rules' under global variabels list and the other lists also but i couldnt found.
    can any one help me in this ?
    regards.
    Seetha.

    Hi Seetha,
               In the LSMW Workbench go to the option user menu.  And check the option display conversion program.
    Now when you execute with the radio button on dislplay conversion program, you ll see the code that got generated in the background while you built your LSMW.
    The global variables that you have mentioned are bound to be there in this program generated in the background..
    You can put a break point here and see for yourself what the value of these global variables are at runtime.
    File port, TRFC port , no. of transactions executed by one run of the LMSW Idoc program , message type are some of the fields that you have asked for .

  • How do I use an array variable in the assignment target?

    Hi,
    I am creating a BPEL process in which I have to use an array variable. The array variable needs to be initialized based on some condition.
    The issue is I cannot find a way to set the value of the array variable. There are ways to GET the value of an array variable indexing into it.
    But how do I set the value by using the Array variable in the <to> tag?
    Any help is appreciated. I am using BPEL 10.1.2.0.2.
    Thanks.

    You can declare a variable of type integer which will server as your index. Figure out based on some condition in your process which index of array to update. Assign to your integer variable you created.
    And have Assign copy operation like this -
    <copy>
    <from variable="Var_Output_FetchDueDate"
    part="OutputParameters"
    query="/ns18:OutputParameters/ns18:DUEDATE"/>
    <to variable="outputVariable" part="payload"
    query="/client:GetCustomerAccountInformationProcessResponse/client:customer/client:accounts/client:account[$Var_Counter]/client:dueDate"/>
    </copy>
    I have been using this in my processes.

  • Use of OLAP variable 0FYTCFP in extracting GL transaction figures

    Hi
    We load data to cube 0FIGL_C01.
    We use the OLAP variable to ensure that we are extracting for the current fiscal year to date, as a full load, with a deletion of overlapping requests in the process chain.
    Our fiscal year ends 30 June. My question is around  special periods and opening of the new fiscal year while posting is still allowed into the old year e.g. on 15 July both the old year and the new year are open as the year end processing is still underway, and special periods 13-16 might also be in use.
    Do I have to wait until the user close the year (a manual step) to then do a "final" run for the year, with the periods specified manually, or is there a way to automate this?
    thanks and regards, Lara

    Hi Sander
    Thanks for the response.
    That;s what I have been doing (run manually after the period is closed). It is not ideal, in my mind, because it (1) relies on someone remembering to do it and (2) has to be done repetitively i.e.at least daily until the "old" period is closed, otherwise reports based on the provider will not be accurate. Again, not hard to do, just a pain when everything else is automated.
    This particular DataSource is not delta enabled, otherwise I would have used the delta loads.
    regards, Lara

  • How can I use Server level variables in a business model based report

    hi gems..
    I have declared one server level variable in the BI Analytics repository.
    Now I have made one business model based report.
    In one column I want to use that server level varible.
    I go to the formula tab of that column and then clicked on variable--> session --> put the name of the variable and click ok.
    But when i viewed the report, it is not showing the dates, rather it is showing the date format I chosed i.e DD-MMM-YYYY.
    please help..

    actually the previous problem got resolved...
    Now when I am trying to apply a filter on a particular column using that server variable, then it is showing that the varible has no value definition.
    I have clicked on the filter tab of that column-->add-->variables-->session variables-->then I put the name of the variable-->click OK.
    the following error is comming-

  • To use two presentation variables based on the period selection in OBIEE

    Dear All,
    I have period prompt in my report, based on the period prompt selection in my report I need to get the start and end dates of the period and apply in the report filter.
    For e.g. Period Name selected in the prompt is "2010 - Q1" (For this Period, Period Start Date = 01/01/2010 and Period End Date is 30/03/2010, which is not going to be displayed in the prompts).
    How can I get the start and end dates of the period into my report filter. I tried using the presentation variable for the period name, but unable to resolve the requirement.
    Your help is highly appreciated.
    Best Regards,
    Rajesh

    Hi Rajesh,
    Create a report A which will give you the period start date and end date and filter it using the period prompt.
    Then filter the main report using the report A start date and end date, using Filter -> Advanced ->Filter based on results of another request .
    Add the report A in separate section on the dashboard along with main report and hide report A section.
    Thanks,
