Reference: http://obiee101.blogspot.com/2009/02/obiee-simulating-drill-up.html One way of simulating this behavior is using the preferred Drill path option. (One of the lesser documented features is OBIEE).Chaeck out the basic Calendar Dimension:
On the Date level add the next higher level (month) in the Preferred Drill Path:
Do the same for Month (quarter), Quarter (year). Check the result:
it's not perfect .....

Alias the table for as many dimensions that you need out of the table and use the original as the fact ... join them in the physical layer appropriately and set up your business model as well.
Physicl aliases are ot necessary, you can have only one table in physical layer. In logical layer, select the fact, duplicate it, then rename and use as dimension. |

You can have only one table in physical layer.
In logical layer, select the fact, duplicate it, then rename and use as dimension. Option2:Alias the table for as many dimensions that you need out of the table and use the original as the fact ... join them in the physical layer appropriately and set up your business model as well
Subject Area:
You can build a subject area with a single physical table. Create two
logical tables (fact and dimension) and map the single table into both. Aggregatable columns become measures in the logical fact table. Create a logical join between the two. You will need to create a logical key for your dimension table, but whether this is defined as a key in the database or not doesn't matter. You can expose columns from one or both logical tables in your presentation layer.

Is it better to cache a fact table or dimension table or both in the BI Server level? Why? (Forget other caches from above question) 56. You recently changed the columns of your presentation catalog as your manager wants to enforce naming standards for all customer facing apps. What happens to all the dashboard requests written prior ot this change? Do they function properly or do they appear broken?

How do you resolve a M:M relationship other than using a bridge table? 62. Lets say that you have three tables joined to each other which have been set to be cacheable at physical layer with Table 1 set at cache persistence time 45 min, Table 2 with 60 min and Table 3 with 30 min. You ran your answers request at 9 AM and again at 9:15 AM and again at 9:45 AM. Is the result set the same for all these 3 runs at different times? If so, Why? If Not, why not? There are transactions going on and data is being updated in these tables almost every 10 min. 63. Lets say you are on your local box with a rpd and want to make sure that it can be edited only in offline mode. How can you accomplish this? Is this possible? What settings would you change? 64. Assume there is no MUDE in your environment. Three developers have been working on three seperate projects and they have developed their rpds. As a Server Admin, you were asked to promote these three rpds. What are the next steps for you as an admin to take care of to move them to QA and production? Are there any OBIEE tools that can be handy with this situation? 65. How do you get this type of interaction in your dashboard report? When clicked on a report column, I want multiple options for drill down. Remember that I did not create any hierarchies in my rpd.
66. Lets say that you want to include a prompt to your dashboard with Start Date, End Date and some measures and dimension attributes. You want to use ‘SQL Results’ feature to automatically populate Start Date and End Date with Start Date as trunc(sysdate – 1) and End Date as trunc(sysdate). What would you do? Will you encounter any errors? How do you rectify this problem? 67. How many business models can a presentation catalog refer to? How many presentation catalogues be created from a single business model? 68. How can we create nested presentation folders (nested presentation tables) in your presentation catalog? Lets say we have ‘Facts’ all lumped together in one folder and sub divide these facts as Facts – Logical and Facts – Strategic folders? How would you create this nested structure in presentation catalog? 69. What are logical keys? Why would you need to create them? Does the physical key gets automatically converted to logical key when the table is moved from physical layer to business model? 70. Lets say you have a report with 4 dimensional attributes and 2 fact measures in the report. Whats the default sort behavior of OBIEE when you try to run the report? On what column/columns does it sort? How do you know this? 71. In the above scenario, Is it better to have atleast one column defined in your criteria manually or just leave it without any sort criteria mentioned? Whats the difference in performance?

To disable OBIEE 11g Server cache follow below steps...
Navigate to the Capacity Management > Performance tab.
Disable or Enable using Checkbox available there.
If it is grayed out. Do "lock and edit the session first, which serialises access to these settings and stops another administrator changing things at the same time.
Press Apply, then then press Activate Changes. This copies the new parameter value into the nqsconfig.ini file,
Restart the BI Server system component to enable the change.

To turn off the Presentation Services Catalog Attribute Cache in OBIEE 11g. We need to set the following tags in the instanceconfig.xml file: <ps:Cache xmlns:ps=”oracle.bi.presentation.services/config/v1.1″> <ps:CatalogAttributes> <ps:Enabled>false</ps:Enabled> </ps:CatalogAttributes> </ps:Cache>

Sometimes evern if you remove
i) removed Distinct in advance tab in report.
2. In rpd unchecked the distinct supported.
Still u can't see duplicate records.. then rownum comes to rescue
Create an logical column with expression : Evaluate('ROWNUM' as INTEGER)
and use this column in report and hide it. Check if RSUM can be help - Use RSUM(1)
else RCOUNT
In your answer request criteria add any column then edit formula (fx button) then enter RCOUNT(1). If you click the "function..." button you can select it from the running aggregate functions - "This function takes a set of records as input and counts the number of records encountered so far." |

This ensures that the filter used in the request is not lost or overwritten by another filter or dashboard prompt that may supersede the request. To apply it on the filter in the Answers Request, select Filter Options button > Protect Filter. See below :
Nice example by debashish on his blog
Let's start with a simple report against the SH repository:
 Put in a basic OR filter Have a look a the result: Make a basic prompt: Put it all on a dashboard:  Select the year 2000: You will see that you loose the "OR" function.
Now go back to your report on the first filter part check the Protect Filter option:  Save your report and go back to the dashboard. Select the year 1999 and press go.  You will see that the "OR" part stays intact.
Now go back to your report on the second filter part check the Protect Filter option:
 Save the report and go back to your dashboard. Whatever year you select the result will not change. |

The GUI of OBIEE 10g answer is already able to report against multiple subject area with the “Combine with similar request”.
This functionallity support only the following set sql clause:
but not all other standard set sql clause such as joins. Even if the GUI of answer can do it, BI Server is able to read and to serve this kind of clause because the logical sql is ANSI SQL 92 compliant. This article show you with a little bit of advanced logical sql how to report against Multiple Subject area with the most use join clause statement in this case: the FULL OUTER JOIN. While writing an advanced logical sql, it's good to keep in mind that:
You can't perform a join condition between table of a subject area but between two subject areas. To develop your Logical SQL, you can use an ODBC client such as the Issue SQL module of BI Presentation Service. This step by step guide is made with the help of the SH sample schema. Articles RelatedDesign of the repositoryFor the purpose of the demonstration, a second fact table will be:
Creation of the second Fact tableSQL> CREATE TABLE FactWithCustomerDim AS SELECT amount_sold - 1 "amount", cust_id FROM sales; TABLE created. Repository DesignSimple picture to see the different repository steps:
Creation of the reportsAgainst the first Subject AreaJust create a simple report such as below:
You can then see in the advanced tab of answer the following logical Sql: SELECT Customers."Cust Id" saw_0, Customers."Cust Last Name" saw_1, "Sales Facts"."Amount Sold" saw_2 FROM SH WHERE Customers."Cust Id" < 10 ORDER BY saw_0, saw_1 Against the second Subject AreaJust create a second simple report such as below:
You can then see in the advanced tab of answer the following logical Sql: SELECT Customers."Cust Id" saw_0, Customers."Cust Last Name" saw_1, "FactWithCustomerDim"."Amount" saw_2 FROM SH2 WHERE Customers."Cust Id" < 9 ORDER BY saw_0, saw_1, saw_2 Against two Subject Areas (Multiple Subject Area)In the 10g version, the GUI of Answer is not able to provide a wizard to create a SQL (answer) against multiple subject with the JOIN clause, you have to create it manually and past it in the advanced tab. To develop your Logical SQL, you can use an ODBC client such as the Issue SQL module of BI Presentation Service. Steps:
SELECT SubjectArea1.saw_0 saw_0, SubjectArea1.saw_1 saw_1, SubjectArea1.saw_2 saw_2, SubjectArea2.saw_2 saw_3 FROM ( SELECT Customers."Cust Id" saw_0, Customers."Cust Last Name" saw_1, "Sales Facts"."Amount Sold" saw_2 FROM SH WHERE Customers."Cust Id" < 10 ) SubjectArea1 FULL OUTER JOIN ( SELECT Customers."Cust Id" saw_0, Customers."Cust Last Name" saw_1, "FactWithCustomerDim"."Amount" saw_2 FROM SH2 WHERE Customers."Cust Id" < 9 ) SubjectArea2 ON SubjectArea1."Cust Id" = SubjectArea2.saw_0 ORDER BY saw_0, saw_1

Step 1:
Login to the EM administration screen using the url http://localhost:7001/em (Replace the hostname and portnumber based on your setup)
Goto the weblogic EM console:
A. RPD and Webcat selection Expand 'Business Intelligence' node on the left and choose Coreapplication.
Now click on the Deployment tab on the right. Next, go to the Repository tab.
Select the RPD you want to use:
Enter ther RPD passwords and press update:
Webcat selection 9. You need to update the path at the bottom of the same EM screen, with the location looking like this. $ORACLE_INSTANCE/bifoundation/OracleBIPresentationServicesComponent/$COMPONENT_NAME/catalog/XXXXXX. Change the path from XXXXXX to SampleApp so the location looks like this - $ORACLE_INSTANCE/bifoundation/OracleBIPresentationServicesComponent/$COMPONENT_NAME/catalog/Name_of_your_Catalog B. Apply changes 10. Click on Apply (top right corner of screen). 11. Click on ‘Activate Changes. C. Start OBIEE services 12. Login to the EM administration screen using the url http://localhost:7001/em (Replace the hostname and port number based on your setup). Use the login you created in BIEE installation to log in. 13. Expand ‘Business Intelligence’ node on the left and choose Coreapplication. 14. Click on the Overview Tab. 15. Click on blue button “Restart” (or green button “Start”) under the Manage System category, middle of screen. 16. Click yes on dialog box to confirm the move. Wait for message that confirms successful restart.

Nice blog on Purging BI Server Cache in OBIEE 11g
To purge BI server cache in OBIEE 11g we need to go through the below process:
Create a text file with a name e.g: say purgecache.txt with below code in it Call SAPurgeAllCache() and save the file in /<MW_HOME>/Oracle_BI1/bifoundation/server/bin directory. Before running nqcmd, you must first run bi-init.cmd (or bi-init.sh on UNIX) to launch a command prompt or shell window that is initialized to your Oracle instance. You can find this utility in: <MW_HOME>/ORACLE_INSTANCE/bifoundation/OracleBIApplication/coreapplication/setup Then, run nqcmd from the resulting shell window with the desired options. For example: nqcmd –d my_dsn –u my_username [-p my_password] –s sql_input_file –o my_result_file You can pass a text file with SQL statements to the utility (script mode), or you can enter SQL at the command line (interactive mode). Queries are run against the default subject area, unless the object names used in the query are fully qualified. For example to purge BI Server cache run below command In windows: nqcmd -d AnalyticsWeb -u <weblogic_admin user> -p <weblogic_admin password>-s purgecache.txt In Unix: ./nqcmd -d AnalyticsWeb -u <weblogic_admin user> -p <weblogic_admin password>-s purgecache.txt

Hi all,
Now it is possible to use all types of variables in the title.It has been acknowledged as a defect with bug no.:6019292.The effective solution they have provided is as follows: For session variables: @{biServer.variables['NQ_SESSION.variablename' ]} Reference:
http://siebel.ittoolbox.com/groups/technical-functional/siebel-analytics-l/want-to-include-a-dynamic-variable-in-title-in-obiee-1569322 For repository variables: @{biServer.variables['variablename']} |

A good tutorial on .CSS can be found here: |
|
Right click "Stop OC4J" shortcut, available at Start>All Programs>Oracle Business Intelligence>Stop OC4J, properties. Now under "Shortcut" tab find "Target" text box, in which lies your password.
look for the word oc4jadmin in "Target" Text box and the word next to it is your password.... |

Recently we have got new bussiness requirement for implementing master-details request..
OBIEE 11g has come up with new feature for Master-Detail linking..
On googling blog on same was found ...
Master-detail linking of views allows us to establish a relationship between two or more views such that one view, called the master view, will drive data changes in the other (connected) views, called detail views. For e.g., let’s assume that we have two views, one a table that shows dollars by region, the other a graph that shows dollars by brand with region on a section slider. Using the master detail linkage, we could connect the two in such a manner that on clicking a particular region, the region in the section slider of the graph as well as the data in the graph will change.

I have been working on a client assignment to implement OBIEE and design and develop dashboards and get them up and running.
One particular requirement was to bring a BI Publisher report into a dashboard. The BI Publisher Report was developed much before the OBIEE came into limelight. The BI Publisher Report is scheduled to run everyday and email the report to certain group of users. Since we have been playing around to set the BI Dashboard and have one dashboard up and running for a specific business area, and so decided to extend this for other areas as well. For one such area where we have the BI Publisher Report has been developed, rather than re-developing the report we have decided to bring the BI Publisher report into the dashboard. The BI Publisher report is -SQL Based Report -Has 2 date parameters. More at:

Aggregate fact tables contain same measure data like in the lowest granularity fact table but summarized on certain level. Aggregates in obiee can be created using aggregate persistence wizard or manually. For the first option: http://www.oracle.com/technology/obe/obe_bi/bi_ee_1013/aggpersist/aggpersist.htm http://www.rittmanmead.com/2007/10/26/using-the-obiee-aggregate-persistence-wizard http://obiee101.blogspot.com/2008/11/obiee-aggregate-persistence-wizard.html Advanced option is using materialized views, dimensions and query rewrite. I'll show the second option (manually). Creating database objects For this example we'll create database objects, higher level dimension tables, aggregates, indexes, ect. Something about higher dimension tables, it depends how you understand normalized and denormalized structure in business intelligence term. Dimension tables are always denormalized, each level is placed inside it. If you for example query sh.products table you'll see that the lowest level has information about high levels. If you are using dimension operator in OWB to load data into, the result is dimension table with addition that all levels are separately loaded with each with its own ID, primary key. So other aggregation fact tables can reference high level dimension ID from the same dimension. The very similar way is how olap dimension works, see global.channel_dimview. Anyway, we'll create higher dimension level tables for this example purpose. create table months as select distinct calendar_month_id, calendar_month_desc, calendar_year_id, calendar_year from times alter table months add constraint months_pk primary key (calendar_month_id); create table categories as select distinct prod_category_id, prod_category from products alter table categories add constraint categories_pk primary key (prod_category_id) create table years as select distinct calendar_year_id, calendar_year from times alter table years add constraint years_pk primary key (calendar_year_id) create table sales_months as select t.calendar_month_id, sum(s.amount_sold) as amount_sold, sum(s.quantity_sold) as quantity_sold from sales s, times t where s.time_id=t.time_id group by t.calendar_month_id; alter table sales_months add constraint sm_months_fk foreign key (calendar_month_id) references months (calendar_month_id) create bitmap index sm_months_idx on sales_months (calendar_month_id); create table sales_year_cat as select t.calendar_year_id, p.prod_category_id, sum(s.quantity_sold) as quantity_sold, sum(s.amount_sold) as amount_sold from sales s, products p, times t where s.prod_id=p.prod_id and s.time_id=t.time_id group by t.calendar_year_id, p.prod_category_id; alter table sales_year_cat add constraint syc_years_fk foreign key (calendar_year_id) references years (calendar_year_id) create bitmap index syc_years_idx on sales_year_cat (calendar_year_id); alter table sales_year_cat add constraint syc_categories_fk foreign key (prod_category_id) references categories (prod_category_id) create bitmap index syc_categories_idx on sales_year_cat (prod_category_id); create table sales_months_cat_ch as select t.calendar_month_id, p.prod_category_id, c.channel_id, sum(s.quantity_sold) as quantity_sold, sum(s.amount_sold) as amount_sold from sales s, products p, times t, channels c where s.prod_id=p.prod_id and s.time_id=t.time_id and s.channel_id=c.channel_id group by t.calendar_month_id, p.prod_category_id, c.channel_id; alter table sales_months_cat_ch add constraint smcc_months_fk foreign key (calendar_month_id) references months (calendar_month_id) create bitmap index smcc_months_idx on sales_months_cat_ch (calendar_month_id); alter table sales_months_cat_ch add constraint smcc_channels_fk foreign key (channel_id) references channels (channel_id) create bitmap index smcc_channels_idx on sales_months_cat_ch (channel_id); alter table sales_months_cat_ch add constraint smcc_categories_fk foreign key (prod_category_id) references categories (prod_category_id) create bitmap index smcc_categories_idx on sales_months_cat_ch (prod_category_id); The focus is on how to implement this in obiee, not how these tables are refreshed with data or recreated as a part of the job of ETL process. Implementation in obiee Physical layer:  Foreign keys: SALES.PRODUCT_ID >- PRODUCTS.PRODUCT_ID SALES.TIME_ID >- TIMES.TIME_ID SALES.CHANNEL_ID >- PRODUCTS.CHANNEL_ID SALES_MONTHS_CAT_CH.CHANNEL_ID >- CHANNELS.CHANNEL_ID SALES_MONTHS_CAT_CH.PROD_CATEGORY_ID >- CATEGORIES.PROD_CATEGORY_ID SALES_MONTHS_CAT_CH.CALENDAR_MONTH_ID >- MONTHS.CALENDAR_MONTH_ID SALES_YEAR_CAT.PROD_CATEGORY_ID >- CATEGORIES.PROD_CATEGORY_ID SALES_YEAR_CAT.CALENDAR_YEAR_ID >- YEARS.CALENDAR_YEAR_ID SALES_MONTHS.CALENDAR_MONTH_ID >- MONTHS.CALENDAR_MONTH_ID BMM: Drag and drop attributes from the physical layer to BMM, for example CALENDAR_YEAR_ID and CALENDAR_YEAR from YEARS physical table to TIMES logical table to create additional logical table sources. We repeat this step for other higher level dimension tables on the physical layer as weel as for SALES_MONTHS, SALES_YEAR_CAT and SALES_MONTHS_CAT_CH aggregate fact tables that contains measures AMOUNT_SOLD and QUANTITY_SOLD.   Dimensions:  On each logical fact table source on the logical fact table SALES we need to set aggregation levels and this is mandatory step for obiee to redirect SQL query on aggregate tables. Aggregate sources are activated on certain levels of dimension.    Test If we add CALENDAR_MONTH_DESC, instead of going to SALES (TIME_ID lowest level) and summarize it on the month level, the SQL query is redirected to SALES_MONTHS:  NQQuery-log:  In case of CALENDAR_YEAR the SQL query is also redirected to SALES_MONTHS:  Some other cases: CALENDAR_MONTH_DESC, PROD_CATEGORY and CHANNEL_DESC:  NQQuery-log:  CALENDAR_YEAR and PROD_CATEGORY:   NQQuery.log:  |
