Compare Java based reporting to OBIEE

Hello All,
Due to a lot of misconceptions, my current client thinks that a lot of their problems will be resolved by simply retiring OBIEE and write all the reports in Java.
Some requirements are unrealistic to ask from OBIEE and some are well...limitations.
The client has asked us to give him reasons why he still should be on OBIEE. Has anyone done a comparison of Java based reports and OBIEE (or any BI tool)?
Reasons why OBIEE stands out would also help.
Thanks all!!

There are many, many reasons why to use OBIEE. One of the bigger reasons being you don't need to know anything about Java in order to build an Answer Report.
I've been asked a similar question in the past, to compare OBIEE versus Java based ADF. My response is that they have two completely different purposes.
--OBIEE is end-user/middle-user driven dashboards and ad-hoc analysis.
--Java/ADF is for power-users to pre-constructed reporting systems. (forgive me but I don't know the ad-hoc capabilities of Java/ADF)
If your client has full-time java resources to commit to the creation and maintenance of a Java environment, then by all means they should probably go that route. But keep in mind that as new uses want to see different data layouts and different data sets, your java team will quickly become overburdened.
OBIEE relieves the strain on the java (IT) team and allows end-users to drive reporting with the relatively occasional support by IT.
Yes, OBIEE does have limitations, but always keep in mind that a) It's an ad-hoc Dashboard framework and not an ad-hoc java framework which has much greater flexibility but requires much more technical expertise b) There is a major release of OBIEE (11g) just around the corner that is about to change the game in terms of how OBIEE can be used. You should have your client stay on board until they can at least see the new features.
Good luck and if you found this post useful, please award points!
Best regards,

Black Block of text in java based report

I am accessing some graphical reports from a labaoratory instrument. The reports are generated by Java. The reports look fine on scree, but the issue come when I attempt to print them. When I use a PC that has IE 6 and JRE 1.5, the reports print fine. When I use an updated PC with either IE 7 or IE 8 and JRE 6.20 or 6.21, the reports just get large black blocks over the text. I can provide a screen shot, it needed.
The instrument vendor cannot recreate the issue, so they will not help.
Does anyone have any ides what might be causing this?

Guy,
You only need to include a profile if you need to convert to another CMYK space when the PDF is outputa typical case for including profiles would be one where you don't really know what the print destination is and your CMYK values might need to be reconverted at output. If you don't want additional CMYK conversions (you know the correct destination is US Sheefed) then export as PDFX/1-a, that preset includes an intent but not a profile and your black will not get converted.
Unwanted color conversions indicate that there are conflicting profiles somewhere.

OBIEE SSO enabling and role based reporting

Hi,
I had installed SOA10.1.3.1.0 and OBIEE10.1.3.4.0 already on my WINDOWS. I understand that I need to install 10.1.4 infrastructure to enable SSO in OBIEE, can you please tell me what is 10.1.4 infrastructure? is it equivelent to Oracle Identity Management Infrastructure and Oracle Identity Federation 10.1.4? I tried to download this from OTN since last night, but the page is always unaccessible. Where can I download 10.1.4 infrastructure except otn?
I have another question regarding to the role based reporting with SSO. We want users to see different reports based on their roles once they login. What options do we have to implement this? From my understanding, we need to maintain a user role mapping table in our database, create groups in OBIEE and map the user role with the group in OBIEE? Is it true? Are there other options? Is there a existing product we can use to implement this?
Thanks,
Meng

Installing Java based Scenarios will effect old 3.0B reports in NW2004s ?

Hi,
Can anybody tell me whether Installing Java based Scenarios will effect old reports running in 3.0B.? or we will be just able to use the new features available after installing Java based scenarios and old queries/ web reports will remain same?
Here I should mention that we are upgrading our BW environment from 3.0B to NW2004s.
Please help me.

Jeet

Hi Prakash,
Thank you very much for your fast reply.I read the blog and it is a lot of very useful information. I have a couple of questions though:
1. <u>Option 3 - Publishing Strategy within SAP NetWeaver 2004s BI</u> - is definately what we need:
"End User Accesses
&#56256;&#56452; Users will be assigned to Groups which have Roles in them
&#56256;&#56452; Therefore, all users will see a tab in the portal navigation for their reports
&#56256;&#56452; KM Navigation iView will be used to link KM Folder with Portal Role per Application Area
&#56256;&#56452; Users will only have 1 access point: Portal Roles"
So If I understood you correctly 1)I need to create Roles in Portal.
2)Assign users to the Roles.
3)Users will have only those roles assigned to them(for ex: sales manager role, AE role and so on)
4)Publish my web quires to PCD and then role.
So this part is clear.
What I still don't understand is how to make the tree menu display in the Role that I will create? And with in the Role to have different folders (in a tree display view) that would have names (links) to differnet web reports (iviews that i will store and publish)? Is there an example with step by step for this?
Is there an example of how to implement the Option 3?
2. <b>Bookmarks</b> - as I understood by "I recommend using the shared BEx Portfolio KM Bookmarks instead of traditional bookmarks" you reffering to 'Save As' button on the run time of the report that lets you save to favorites, Myportfolio... I have no problem of using it but is there a way:
1) bypass the selection screen when executing the saved KMbookmark? I tried saving it under the my favorites and when executing it brings me to the selection screen first (I could use variants for selection screen, so what is the use??!!)
2)how can i send this saved bookmark by e-mail to a collegue? Is there a way? If not may be there are a new concept that we don't understand?
Thank you very much again.

Bad performance of Java Web Report in BI 7

We are experiencing poor performance with Java web application(EP)
comparing to that with ABAP web.
We migrated our BI reports from the ABAP web interface to the Java web
interface due to our upgrade to Netweaver2004 environment.
The problem is that it takes much longer time to load the BI reports in
Java web than in ABAP web.
It is the same situation in RSRT. Java web needs more time to execute
the same query.
there is no EP logon performance delay, so I think the EP is configured good.
But the response time of BI Java Web Report is delayed average of 4~5
seconds in every Query compared in that of ABAP Web report.
Anyone experience this situation?

Hi,
I am facing similar problem. How did you solve it?

Extremely slow performance in comparison to RDC-based report

Today our application uses the Crystal Reports RDC. In the last
ten years we have made good experience with Crystal Reports.
In the next few months we want to migrate our application to
JAVA.
Because the reports offer a great reuse-potential, we would like
to implement them via CR4E.
But during the first benchmark tests we made a very bad experience.
Running (Printing) in CR4E the reports needed from 20 up to 480 percent
more time in comparison to the RDC-based reports.
When using POJOs need from 25 up to 570 percent more time.
When printing the reports from within the CR2008 designer there is
no performance difference.
The reports have from 4 to 82 pages.
We didn´t expect such a huge performance difference.
Is CR4E in general slower than the RDC-based Crystal Reports?
Or are there any parameters in CR4E in addition to the RDC-based
solution for tuning the reports?
Edited by: Rainer Graedtke on Nov 9, 2009 2:44 PM

Hi Ted,
thanks for the fast response.
Is there another "datasource option" with better performance than POJO?
In the upcoming JAVA-version of our application we would like to "feed"
our reports from memory, not from the underlying database.
One more statement concerning our performance problem:
In our reports we make extensive use of subreports.
Each report has the minimum of two subreports, one for the pageheader,
one for the pagefooter.
This is necessary because we have changing headers and footers
depending on the contents of the details.
The report with the largest performance loss contains 29 subreports!
RDC-based it prints in 10 seconds, Java-based we need over 50 seconds.
Is there any suggestion how to improve the performance of our reports in
JAVA/CR4E other than reducing the number of subreports?
Another question concerning the keycode-problem:
We have designed the reports in the CR2008 Designer and we want to run
them under CR4E. Is this a valid approach?
Sincerely Rainer

Browser performance issue when Calling BI Publisher report from OBIEE dashb

Hi Techies,
We installed OBIEE 10.1.3.3 on SunOS 5.9 unix box.This is PROD env.We are calling BIPublisher report from OBIEE dashboard by clicking the BIP reports link on OBIEE dashboard.After clikcing the link BIPublisher report is opening in another browser window.But is it taking time.
Plz tell me how can we reduce the time taken to open BIPublisher report window when we cilck on the report name in OBIEE dashboard
Thanks,

Suresh
There is no out of the box method to get the EBS report to OBIEE. You could look into moving the EBS report to a mountable web server directory after it completes and then show it in OBIEE via a link or html object. You will need to rename the report of course, every time you run it its going to change names.
In an after report trigger you could call a small java class to move and rename the file for you.
Alternatively, recreate the report in the standalone version. Be aware that you are going to have to set orgs yourself, BIP is not aware of orgs outside of EBS

BI Publisher report in OBIEE Dashboard

Hi,
I have a BI Publisher report that consists of:
-SQL Based Report
-Has 2 date parameters
This report is independent of any data source OBIEE, ie there is no repository for the data shown in the BI Publisher report.
I need to show this report in OBIEE dashboard with parameters. The report should get a parameter from a prompt / dynamic var.
I have understood according, there are two methods for achieving this:
1. Create a BI Publisher Report using BI Answers report as the data source wherein the BI Answers report would have one of the column’s filter clause as “is prompted”.
2. Create a BI Publisher Report using BI Answers/Database as data source. Create a parameter for the BI Publisher report and then match this parameter name while assigning the presentation variable for the dashboard prompt.
But I can not implement this, because my BI Publisher report is independent of any data source OBIEE.
There a way to solve this?
Thanks in advance!

When you create the parameter in Report, and embed that in BIPublisher report section, it will display the parameter in the embedded content itself.
see, if you can make use of this.

How to apply filters for union all report in OBIEE 11g

Hi All
Can we apply saved filters to union reports in obiee 11g?
I am able to apply saved filters for normal reports but not for union reports.
The catalog pane is blank, when i click on result columns or each criteria.
The only option i see is to manually create the filters for each criteria, dont i have any choice to use a saved filter for union report?
Is this a bug or something i am unaware. Please guide me
Thanks

Hi manu,
Filter is created based on subject area.we can't use save filter in any other subject areas.
now we can use new filter for union reports.
if Helps please mark as correct.. :)

How to build a Analysis report in OBIEE 11g

Hi All,
I have a query regarding 'How to' to build an analysis report in OBIEE 11g.
The data model is a financial data model, where information such as Actual, Plan, Forecast, What - if etc for current AND prior year need to be displayed in a dashboard.
I created two analysis reports one for current year Rep1 and second for prior year Rep2 each with filter criteria as current year and prior year respectively based on years column. and then in the dashboard I created prompt based on scenario column (radio button) for Actual, plan, Forecast, and wht if.
I am able to show the current vs prior year data in the same dashboard for Actual or Plan or forecast or what if (depending on data availability in the database).
I want to achieve the same information in a single analysis report instead of two separate analysis reports. I do not want to create separate physical report for current and prior year data.
I need one analysis report which I can use in dashboard and depending on selection for scenario (actual , plan, forecast or wht if) I want to show the current AND prior year data the way I achieved in with two seperate reports embedded in their respective sections as explained above.
Does any one have idea how to achive this by building single analysis report?
If you need any more clarificaiton or have any queries, please let me know.
Thanks and Regards
Santosh

As per I understand your requirement,
In your Dashboard create a Presentation variable which receives the value of year you select.
Now in your analysis, select the year column along with all the measures you want (Actual, plan, Forecast, and what-if, etc).
Create a filter on Year column and convert it into SQL. Put the condition as:
"Year" BETWEEN @{Presentaion_Variable} - 1 AND @{Presentation_Variable}
You will get the result for selected year and the previous year.
Hope it helps..

Union report in obiee 11g problem

HI,
    I build union report in obiee 11g.In that report i have one column i.e Financial month.I have excluded Financial month column in table view.
    Now my requirement is I have to show results based Financial month at dashboard.For example if i select particular month in dashboard prompt,that month data has to reflect on dashboard.
    For getting results I created one dashboard prompt i.e Financial month and kept 'is prompted' at report level.But am not getting results means if i select any value from Financial month prompt then the report on         dashboard will not reflect.Please help me how to get data based on Financial month.
Regards,
Kumar.

Hi,
you said about writing query in DB.......whether U meant of trying checking the query in toad..or something else..........
Since im giving only one join from dim to fact in the physical diagram........
But more than one join exist between those dim and fact, but im giving only one join mainly the primary key column of the dimension table to the fact table....Whether i need to give all the joins that exist(even if it has 2 or 3 joins between those fact and dim) tables....
If i give count distinct means it is giving count for every nation as 1....like i mentioned below
NATIONALITY<----------------------------------------------------->NATION COUNT
INDIA---------------------------------------------------------------------1
AUS------------------------------------------------------------------------1
CAN------------------------------------------------------------------------1
Since you said to check about depts of the particular column....i couldn't able to understand about "depts" that you meant????
Whether i made any logical mistake...........
thanks,
Harry...

SAP R/3 and JAVA based data base

hi,
I have two data base one is SAp r/3 and another is JAVA based.
i need to link one table from Sap r/3 and one from JAVA based data base.
using crystal reports how can i do this????
thanks

hi,
in Crystal reports go to data base expert in the pop up link JAVA based data base using JDBC and connect SAp r/3 using SAP.
You will be able to get SAp menue only if you are using crystal reports version 2008 or version 12.
Once the connection is established select the tables you require and rest remains same.
Thanks.

Calculationg current and past year for a Analysis report in obiee 11.5

Dear All,
Need some help here.
I am a beginner in OBIEE and need some help to build a report in obiee 11.5 as described below;
I need to create a PnL report such that I show current years profit and loss AND prior year profit and loss figures in a report side by side for comparitive analysis for user.
My data is an essbase database, and have a years dimension with values 'current year' , 'F08', and 'Prior Year'. and other measurs such as revenue, % revenue, gross profit, cost of sales, operating expenses etc. (I am using 107 from oracle downloads) for obiee 11.5
There is another dimesion called time period with members as Q1, Q2, Q3, and Q4, and each having respective months (e.g. Jan, Feb, Mar for Q1 etc)
I also have a scenario dimension with members as Actual, plan, Forecast, Wht -if..
Now I need to create a this report.
I created this report based on approch no 1 below;
Appraoch 1
- Create two analysis reports with all the above columns.
- specify filter for year column equal to current year for first report
- specify filter for year column equal to prior year for second report
- create a dashboard with a promt (radio button) based on column scenario
- create two sections placed side by side below the promt and place above two reports in those two sections so that they appear side by side
Nw when I run this dashboard, it works fine, and shows me the current and prior data for actual, plan etc...
BUT....
I need to create the same reports using a single analysis report instead of two separate reports with hardcoded values for year filter.
Now I tried use AGO funtions on but , it requires a column with numerical value so that it can calculate the past year, but in my case year is a column hving text value and hence i cant use it.
I would like to know how to build such a report using any other variable or function or any rpd level modifitions.
If I had a year dimesion with numeric values, then how would I use to calculate the past year once u select current year .?
Let say values are 2012, 2011, 2010 etc. so If I select 2012 as current year, I should get data for 2012, and 2011, if I select 2011, then I should get data for 2011 ,and 2010.
Please help me to build logic either at analysis level or at repository level
Thanks and Regards
Santosh

Hi,
As per I understand your requirement,
In Pivot table, place 'Year' in pivot columns instead of rows.
Create an SQL filter on Year and put the condition as:
*"Year" BETWEEN @{Presentation_Variable} - 1 AND @{Presentation_Variable}*
You will get the result for selected year and the previous year.
Hope it helps..

A.K.
